Supercritical fluids technology for clean biofuel production

Biofuels are liquid or gaseous fuels that are predominantly produced from biomass for transport sector applications.As biofuels are renewable,sustainable,carbon neutral and environmentally benign,they have been proposed as promising alternative fuels for gasoline and diesel engines.This paper reviews state-of-the-art application of the supercritical fluid(SCF)technique in biofuels production that includes biodiesel from vegetable oils via the transesterification process,bio-hydrogen from the gasification and bio-oil from the lique-faction of biomass,with biodiesel production as the main focus. The global biofuel situation and biofuel economics are also reviewed.The SCF has been shown to be a promising technique for future large-scale biofuel production,especially for biodiesel production from waster oil and fat.Compared with conventional biofuel production methods,the SCF technology possesses a number of advantages that includes fast inetics,high fuel production rate,ease of continuous operation and elimination of the necessity of catalysts.The harsh operation environment,i.e. the high temperature and high pressure,and its request on the materials and associated cost are the main concerns for its wide application.     

燃料对高磷鲕状赤铁矿气化脱磷的影响

以酒泉烟煤、阳泉无烟煤、焦煤混合物和木炭作为燃料,在900℃下模拟烧结预热层进行焙烧,研究燃料种类和用量对气化脱磷的影响。结果表明：由于不同煤和木炭的挥发分不同,对于气化脱磷的影响不同,在配碳量为4％时,挥发分最高的烟煤脱磷效果最好。
