Abstract
Reports results of a study of a series of metal hydrides (M = Zr, Hf, Ta, W) supported on silica–alumina in hydrogenolysis of light alkanes in a continuous flow reactor. Researchers obserbed a difference in the reaction mechanism between d0 metal hydrides of group 4 and d0 ↔ d2 metal hydrides of group 5 and group 6.
In addition, they demonstrated the potential application of the catalysts by the transformation of Fischer–Tropsch wax in a reactive distillation set-up into typical gasoline and diesel molecules in high selectivity.
