Dual fluidized bed steam gasification system is a successful system that has been researched and commercially developed for more than 20 years. Presently, a 3.8 MWth DFB steam gasifier plant for electricity production has been installed in Nongbua district, Nakhonsawan province in Thailand. This is the only commercial dual fluidized bed system in Thailand at present time. To optimize the operation conditions of the DFB gasifier system, bed materials and their catalytic activity were investigated as it affects the steam gasification reactions and thus the system performance. The unused and used bed materials were preliminary analyzed using scanning electron microscopy and energy dispersive spectroscopy. The results showed better gasifier performance were achieved when calcium was presented on the olivine, which was re-activated in the DFB gasifier after certain period of time.

Biodiesel is a renewable, with high combustion efficiency but low emission as a replacement of limited reserves of petrodiesel. On the other hand, biodiesel as a fuel has a problem caused by its instability against oxidative degradation. This reaction might decrease the quality of biodiesel as the product of the reaction potentially harm the diesel engine during combustion. Therefore, antioxidant additive should be added to biodiesel to prevent the oxidative degradation. Among several phenolic antioxidants, pyrogallol has been known/mentioned as one of the best antioxidant additive for biodiesel. However, the solubility of pyrogallol in biodiesel is relatively low. In the previous study, the addition of alkyl group to pyrogallol’s benzene ring has been done in order to increase the solubility of pyrogallol in biodiesel. Pyrogallol was reacted with methyl linoleate through oxidative coupling reaction using 2,2-diphenyl-1-picryhidazyl (DPPH) resulting a new synthesized product. Unfortunately, the reaction resulted a mixture of products containing unreacted pyrogallol, DPPH, dimer of pyrogallol, and low concentration of the synthesized product. The synthesized product was separated from the mixture to get the higher concentration. The difference in molecular size led to the separation of synthesized product from the mixture through molecular sieve zeolites. Zeolites has been widely used as molecular sieve to separate the mixture based on molecular size. In this research, the product mixture was separated based on the molecular size through adsorption using 3 types of zeolites which has different pore sizes: SAPO34 (4Å), Na-Y (7Å) and 13X(10Å). The result confirmed that different pore size of zeolites could successfully separate the synthesized product from other components in the mixture.

Indonesia has a huge number of backlog, it is estimated at around 11.4 million unit in 2015. It has been sugested that vertical housing becomes one of the solution at fulfilling the housing need in the urban area in Indonesia. World Green Building Council reports that buildings contribute to 33% of carbon dioxide emission, 17% of water consumption, 25% of wood consumption, 30–40% of raw materials consumption, and 40–50% energy consumption in its construction and operation. Based on those facts, therefore, an environmentally sound development should consider building energy consumption. Green Building concept is being trusted as a way to solve this issue, but the local authority of Indonesia lacks of green criteria assessment for vertical housing. Through this study, it is expected to obtain some simple categories about green building concept for vertical housing. The methodology of this study, uses qulitative analysis by collecting perception from some respondents thhrough various ages and professions. The data is collected through online quetionnaire. The data determines to some key words and categories to see the distribution and corespondence on each answer. The result shows that respondents considered the Indoor comfortability and outdoor management being the important criteria that must be noticed on implementing green building design concept in vertical housing. It is caused by a half of respondents’occupants are not related to green building. This study is expected to be developed or considered for next study about green building assessment criteria for vertical housing in Indonesia.

In the present work thermal performance of Direct Absorption Solar Collector (DASC) with TiO2-water (nanofluid) as working fluid was investigated experimentally. DASC utilizes the principle of volumetric absorption i.e. solar energy absorbed by a thin film of working fluid flowing over the collector plate. The experimental study was carried out in four phases; in first phase flow rate was kept 2 lpm and volume fraction of nanofluid was changed from 0.001% to 0.007%, in second and third phase same procedure was followed for 2.5 lpm and 1.5 lpm flow rates respectively. In fourth phase the experiment was carried out with water for 1.5 lpm, 2 lpm and 2.5 lpm and the performance of collector was analyzed. Results obtained suggest that for water as a working fluid, thermal performance of the DASC at 2 lpm was better. Secondly, when nanofluid was used as a working fluid, thermal performance of the collector was found better for 0.005% volume concentration.

Biodiesel waste (glycerol) valorization has been gaining interest currently due to the unique structural characteristic of the compound to be processed into many valuable commodities. The current study is focused on the catalytic hydrogenolysis of glycerol to 1,2-propanediol over Ru supported on NaY-Zeolite catalyst via a sustainable route. The catalysts with variable Ru loading (1-5wt%) synthesized by wetness impregnation method were tested for the selective hydrogenolysis of glycerol in a continuous fixed bed reactor at atmospheric pressure and moderate temperatures (160-240 °C). The physicochemical properties of the catalytic materials have been characterized by FTIR, XRD and SEM-EDX techniques. It was observed that the synthesized catalyst remained stable and retained the high crystallinity upon increasing Ru loading and the stretching vibrations of the silica-alumina structure exhibited no difference before and after metal impregnation. Reaction parametric studies performed to compare the effect of calcination and reaction temperature on the catalytic performance during glycerol hydrogenolysis suggested that calcined catalyst has better activity towards glycerol conversion as compared to that of the uncalcined catalyst. Optimization of other reaction parameters such as metal loading, catalyst weight, glycerol concentration, glycerol flow rate as well as hydrogen flow rate is expected to elevate the selectivity towards 1,2-propanediol to a greater extent.

Supercapacitor is an environmentally friendly energy storage device, which fills the gap between traditional capacitors and batteries, and its energy density and power density are higher than the battery [1]. Moreover, the supercapacitor has the characteristics of high charging and discharging efficiency and long cycle life. This makes it used in the electric vehicles, high powered weapons, standby power in electronic equipment, flash of industrial equipment and ignition device [2]. So it has great significance for the basic research, the development of electronic industry and the electric vehicle to carry out the supercapacitor electrode materials [3]. Here, we firstly prepared the activated carbon materials by carbonizing, activating the biological material, then prepared the nickel hydroxide/activated carbon composites by direct precipitation method, and studied the electrochemical properties of composite materials with different nickel hydroxide (Ni(OH)2) contents (the mass fraction). The results of cyclic voltammetry and constant current charge-discharge are that a small amount of Ni(OH)2 are mixed in the carbon surface and pores, the composite material has a good specific capacitance, stability, charging and discharging performance compared with the activated carbon. When the mass fraction of Ni(OH)2 is 12%, the supercapacitor exhibits the excellent electrochemical properties, its capacitance is up to 400.78F/g which improved 75.21% compared with the activated carbon’s capacitance (228.74F/g). 6mol/L potassium hydroxide (KOH) is used as an electrolyte, the capacitance is only reduced to 94.42% after conducting 1000 times cycle life tests. This means that the supercapacitor shows a good stability.

Green Building, also known as green construction or sustainable building, is the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building’s life-cycle: from siting to design, construction, operation, maintenance, renovation, and deconstruction. It often emphasizes taking advantage of renewable resources, e.g., using sunlight through passive solar, active solar, and photovoltaic techniques and using plants and trees through green roofs, rain gardens, and for reduction of rainwater run-off. This paper deals with the studies of glazed windows which are capable of transmitting maximum day light with minimum heat radiation. Two criteria had been considered in case of glazings ie light transmittance and heat gain; however one factor have to be compromised for the other. An experimental setup has been developed to study the light and heat transmission characteristics of glazing. Experimental study shows that the double glazed window is good in terms of visibility and mitigation of thermal transmittance.

Real time monitoring systems in photovoltaic (PV) power generation are very important and urgent in some cases. This paper proposes a real time monitoring system for solar panel using the Atmega 2560 arduino which is connected with voltage sensor, current sensor and temperature sensor. The Arduino ATMega 2560 also connects with the Wifi module as a connection to the smartphone to display the measurements of current, voltage and power of solar panel and ambient temperatures through the Blynk app. This system is tested for seven days starting at 08.00 am to 04.00 pm. The designed monitoring system has a good degree of accuracy with an average error rate of monitoring results of solar panel output value below 10%. Monitoring the performance of solar panels using a smartphone-based microcontroller can be done in real time. The monitoring system can be developed for the larger PV systems.
