美国爱达荷国家实验室(Idaho National Laboratory)于2010年6月3日宣布,可将超临界/固体催化剂(SSC)应用于从废弃的脂肪、油类和油脂生产生物柴油。该SSC催化剂可以处理含100%游离脂肪酸(FFA)、含水30%以上和高含杂质如硫、磷、钙等的废弃油脂。SSC催化剂与超临界流体溶剂和醇类在特定温度和压力下与脂肪或油的原料混合,可在一个单一的超临界步骤中完全溶解这些物料。这种方法克服了一个关键的障碍:传
Idaho National Laboratory announced on June 3, 2010 that supercritical / solid catalyst (SSC) can be used to produce biodiesel from discarded fats, oils and fats. The SSC catalyst can treat waste oil containing 100% free fatty acid (FFA), containing more than 30% water, and high impurities such as sulfur, phosphorus, calcium and the like. The SSC catalyst is mixed with the supercritical fluid solvent and alcohol at a specific temperature and pressure with the fat or oil feedstock to completely dissolve the material in a single supercritical step. This method overcomes a key obstacle: Biography
