Abstract

Abstract The simulation modelling of air-CO2 and air-steam-CO2 gasification of the aggressive weed, Parthenium hysterophorous is performed using an ASPEN Plus simulator and the outcomes are compared with an existing gasification study taken from the literature. The effect of temperature on the biomass gasification process, and the generation of the gases carbon monoxide (CO), carbon dioxide (CO2), hydrogen (H2), and methane (CH4) are estimated in the temperature range of 300 – 1000 °C. The objectives of this study are to identify the important processes within the operating variables of elemental parameters with the gasifying agents (air-CO2 and air-steam-CO2) and to understand how temperature impacts the yield of syngas. Research findings from the gasification of biomass by air-CO2 and air-steam-CO2 are also used for comparison. The syngas yield appears to be significantly impacted by temperature variation. Due to the introduction of CO2, the studies of the gas evolution in this gasification process demonstrate a substantial increase in the output % of H2 and CO due to the introduction of CO2.

ASPEN加模型的空气-二氧化碳和空气-蒸汽-二氧化碳气化的Parthenium hysterophous富氢和一氧化碳合成气生产

利用ASPEN Plus模拟器对侵略性杂草Parthenium hysterophorous的空气- co2和空气-蒸汽- co2气化进行了模拟建模，并将结果与现有文献中的气化研究结果进行了比较。温度对生物质气化过程的影响，以及一氧化碳(CO)、二氧化碳(CO2)、氢气(H2)和甲烷(CH4)气体的产生在300 - 1000℃的温度范围内进行了估计。本研究的目的是在气化剂(空气-二氧化碳和空气-蒸汽-二氧化碳)的基本参数操作变量范围内确定重要过程，并了解温度如何影响合成气的产量。本文还比较了空气- co2和空气-蒸汽- co2气化生物质的研究成果。合成气产率明显受温度变化的影响。由于CO2的引入，对气化过程中气体演化的研究表明，由于CO2的引入，H2和CO的产量百分比大幅增加。

期刊介绍： Current energy systems need a vast transformation to meet the key demands of the 21st century: reduced environmental impact, economic viability and efficiency. An essential part of this energy revolution is bioenergy. The movement towards widespread implementation of first generation biofuels is still in its infancy, requiring continued evaluation and improvement to be fully realised. Problems with current bioenergy strategies, for example competition over land use for food crops, do not yet have satisfactory solutions. The second generation of biofuels, based around cellulosic ethanol, are now in development and are opening up new possibilities for future energy generation. Recent advances in genetics have pioneered research into designer fuels and sources such as algae have been revealed as untapped bioenergy resources. As global energy requirements change and grow, it is crucial that all aspects of the bioenergy production process are streamlined and improved, from the design of more efficient biorefineries to research into biohydrogen as an energy carrier. Current energy infrastructures need to be adapted and changed to fulfil the promises of biomass for power generation. Biofuels provides a forum for all stakeholders in the bioenergy sector, featuring review articles, original research, commentaries, news, research and development spotlights, interviews with key opinion leaders and much more, with a view to establishing an international community of bioenergy communication. As biofuel research continues at an unprecedented rate, the development of new feedstocks and improvements in bioenergy production processes provide the key to the transformation of biomass into a global energy resource. With the twin threats of climate change and depleted fossil fuel reserves looming, it is vitally important that research communities are mobilized to fully realize the potential of bioenergy.
