| 摘要 |
An H-Coal Process hydrogenation operation and catalyst life is substantially improved when using colloidal particles of catalyst comprising a colloidal matrix of silica, alumina, titania and combinations thereof coated with hydrogenating components selected from cobalt, molybdenum, nickel, tungsten and combinations thereof. The colloidal catalyst activity may be altered by alkaline promoters, other metals and acidic promoters.
