High temperature shift reactor design
WebSlurry-bed FT reactors offer better temperature control and higher conversion. Slurry-bed FT reactors are also being developed by other Fischer-Tropsch technology vendors, namely Exxon and Shell. Fluidized-bed FT reactors were developed for high temperature FT synthesis to produce low molecular gaseous hydrocarbons and gasoline. WebAbstract. Water-Gas Shift Reaction (WGSR) has become one of the well-known pathways for H 2 production in industries. The issue with WGSR is that it is kinetically favored at high …
