Hydrogen production from biomass-derived glycerol can be conducted by different reforming pathways. Thermodynamics analysis in this work presented that aqueous phase reforming (APR) is prior to steam reforming (STR) process with regard to CO level, and methanation should be limited kinetically in APR process to maximize hydrogen generation. Experimental work demonstrated that methanation could be suppressed by careful selection of catalyst, and a platinum catalyst was seen to behave better than a nickel catalyst. In addition, the distribution of gas products was much closer to the thermodynamic calculations (without methanation) over platinum-catalyst than that over nickel-catalyst.

The modified sepiolite clay catalyst cleaned by nitric acid, impregnated copper nitrate, drying and then calcinations, combined with non-thermal plasma produced by dielectric barrier discharge reactor to remove NO. With XRD analyzed pattern of original and modified sepiolite, the Mg element and others were effectively removed from the original sepiolite by cleaning with nitric acid; the stable phase CuO was formed in the surface of catalyst after immersion and calcinations; the structure of sepiolite almost did not changed after modification so the sepiolite has a good ability to act as catalyst carrier. SEM micrograph of the sepiolite catalyst indicated the number of micro hole were improved and the surface area was increased by treatment, the active point of CuO was uniformly distributed in the surface without stack mess. The results show the acid concentration, cleaning time has an effect on NO removal ratio. Catalyst activity increased and then decreased with increasing of the acid cleaning time. The ratio increased with the increasing of input voltage. The modified sepiolite catalyst has a good ability to adsorb and store NO and take on Barrier Dielectric for Discharge. The order NO removal ratio is as follows: (plasma+ catalyst with acid cleaning, copper nitrate immersed and calcinations) > (catalyst with acid cleaning, copper nitrate immersed and calcinations) > (plasma+ sepiolite catalyst without acid cleaning, but copper nitrate immersed and calcinations) > (plasma+ original sepiolite) > only plasma. When the input voltage was 35kV, the nitric acid concentration of 1.5mol/L used to immerse original sepiolite for 48h, 8% CuO was loaded in the sepiolite surface and the catalyst was calcinated at 500°C for 5h, the maximum ratio value may reach 71%. The This research has been supported by the National Natural Science Foundation of China (No.21076002) investigation proved that the modified sepiolite catalyst combined with non-thermal plasma had a good ability to remove NO.

Flow behavior and heat transfer performance of gas and particles in a vertical tube are modeled by means of the combination of large eddy simulations for both gas and solid phase, and the kinetic theory of granular flow for particle collisions. The subgrid-scale viscosity model and subgrid-scale thermal conductivity model for gas phase and solid phase are based on the Smagorinsky form. The predicted average convective heat transfer coefficients are compared to experimental results measured by Depew et al., and show similar trends between simulations and experiments.

The surface plasmon polariton (SPP) is a novel approach for light trapping in solar cells. SPP enhanced nanocrystalline silicon thin film solar cells were studied in this work. Based on Mie's theory, the optical properties of Ag, Al, Cu, and Au nanoparticles were investigated approximately. The results show that the normalized scattering efficiency, scattering fraction and resonance frequency of SPP can be tuned effectively by dielectric environment, particle size and metal material. The bandgap of nanocrystalline silicon thin film were calculated based on the quantum confinement effect. To enhance the light absorption of solar cells, the resonance wavelength should be on the edge of the bandgap of absorbers, according to which the optimized matches of SPP mode and silicon grain size were discussed. As an example, 20nm Cu particles can be used in nanocrystalline silicon solar cells which contain 5.7nm silicon grains.

The AVS, SEM, SEM-AVS and their distributions were analyzed. The result shows: AVS in the surface sediment of the sea area was between 0.152 and 1.847µmol/g (dry weight), with mean value being 0.935µmol/g (dry weight); SEM in the surface sediment of the sea area was between 0.899 and 1.863µmol/g (dry weight), with mean value being 1.327µmol/g (dry weight);The SEM-AVS in the surface sediment of the sea area was between - 0.594 and 1.365µmol/g (dry weight), with mean value being 0.392µmol/g (dry weight); The metals (SEM) in the surface sediment of the Yellow River mouth probably had some toxicity to the life; the metals (SEM) in the surface sediment of the east and north of the sea areas are safe; the toxicity of metals (SEM) in the surface sediment of the Laizhou bay gradually diminishes.

Global warming is one of the important environmental issues which the world must be faced. The greenhouse effect is a major cause of global warming, while carbon dioxide is the effect of greenhouse gas. Therefore, to solve the environmental problems of global warming, we must restrict carbon dioxide emissions. Carbon emissions trading have proven to be the most effective emissions reduction system which is also bound to the Low Carbon Economy mode of China. Therefore, to explore the development of China's carbon emissions trading and improvement has important theoretical and practical significance.

Modification of diatomite and adsorption of phosphorus from Eutrophication water by modified diatomite have been researched. It was found that the characteristic of diatomite has been change after modified, especially the surface area, number and size of micropores were increased obviously, the surface area of modified diatomite had increased 23 times. Phosphorus sorption was affected by the temperature and pH value, if temperature was higher, the adsorption balance time is shorter; adsorption capacity was decreased when pH value was increase between 4 to 11. Pseudo-second reaction kinetics equation could describe characteristics of phosphorus sorption well, phosphorus sorption behavior of modified diatomite can be simulated by Freundlich adsorption isotherm model.
