✦ Synopsis
are based on an effective composite extractant, sulfuric acid and water (SA-H20), which has high efficiencies for extraction and recovery of sulfides from light petroleum fraction as well as FCC and RFCC gasoline. The sulfides and part of thiophenes in gasoline are separated and identified with the help of GC/FPD and GC/MS analysis, the contents of individual sulfides and thiophenes in FCC and RFCC gasoline were determined. Cheo, J. et al. Huagong Xuebao, 2003, 54, (4), 516-523. (In Chinese) A review of the development of key techniques in Fischer-Tropsch synthesis, namely catalysis, kinetics and reactor engineering. Firstly, catalysis is discussed with respect to catalyst formulation, preparation and nature of active sites. The catalyst formulation is consists of four components, which are reviewed in detail. Preparation methods such as impregnation, proportion and sol-gel are compared. A proposal of active sites is also presented. The new trends in kinetics study are discussed. A general rule for choice of reactor is given and several topics in slurry bed reactor are highlighted.
