Conversion of hydrocarbon gases to liquid in the fluidized bed retort | 1987-06-12 | | A free radical steady-state mechanism has been developed to explain qualitative and quantitative aspects of the generation of hydrocarbon gases in the solid-recycle fluidized bed retort. The mechanism relies on what is known about butane cracking. The 1- and 2-butyl free radicals have been studied a... |
