棕色油脂是在下水道系统和污水处理厂中积累的油性固体和半固体的总称。之前已经表明，棕色油脂经历热解以形成7至17个碳原子之间的烷烃和1-烯烃的同系系列，以及少量的高达约30个碳原子的高级烃和酮。初始研究以批量模式进行，规模为至多50克起始物料。然而，对于燃料和商品化学品的大规模生产，连续工艺通常更有效。这项工作描述了一个连续过程的研究和开发。第一步是确定所需的反应器温度。棕色油脂主要由饱和和不饱和脂肪酸组成，它们以不同的速率反应，产生不同的产物和中间体。中间体包括酮、醇和醛，并且Fe（III）离子催化至少一些反应。通过监控Pyrol...
Brown grease is a generic term for the oily solids and semi-solids that accumulate in the sewer system and in sewage treatment plants. It has previously been shown that brown grease undergoes pyrolysis to form a homologous series of alkanes and 1-alkenes between 7 and 17 carbon atoms, with smaller amounts of higher hydrocarbons and ketones up to about 30 carbon atoms. The initial study was performed in batch mode on a scale of up to 50 grams of starting material. However, continuous processes are usually more efficient for large scale production of fuels and commodity chemicals. This work describes the research and development of a continuous process. The first step was to determine the required reactor temperature. Brown grease consists largely of saturated and unsaturated fatty acids, and they react at different rates, and produce different products and intermediates. Intermediates include ketones, alcohols, and aldehydes, and Fe(III) ion catalyzes at least some of the reactions. By monitoring the pyrol...
