Advancement in the field of biomass and bioenergy has pulled in researchers to produce biofuels derived from naturally accessible feedstock by adopting diverse innovative approaches in biomass pretreatment. In this study, pyrolysis of micro algae with downstream processing of biomass from the resonator cavity under atmospheric pressure was conducted and hydrogen production produced under different microwave power was analyzed. With the increase in microwave power, the hydrogen gas yield accounted to be as twice as that at lower power, where the concentration of produced hydrogen accounts for about 30.80%, 33.20%, and 37.58% at microwave power levels of 800, 900 and 1000 W. It was also observed that no methane was produced in this study since most of the methane produced from microwave plasma conversion has reacted with CO2 and produced CO and H2, hence dropped in the concentration of CO2 with decline in power intensity.

在大气压下辅助微波等离子体反应器中下游螺旋藻干藻生产氢气

生物质和生物能源领域的进步吸引了研究人员通过在生物质预处理中采用多种创新方法来生产从自然可得的原料中提取的生物燃料。在这项研究中,在大气压下进行了微藻的热解和谐振腔内生物质的下游处理,并分析了在不同微波功率下产生的氢气。随着微波功率的增加,氢气产量是低功率氢气产量的两倍,在微波功率水平为800、900和1000时,氢气产生的浓度分别约为30.80%,33.20%和37.58%。 W.还观察到在这项研究中没有产生甲烷,因为微波等离子体转化产生的大部分甲烷已经与CO 2反应并且产生CO和H 2,因此随着功率强度的降低,CO 2的浓度下降。
