Abstract:
1. A method of producing liquid fuels with zero carbon dioxide emission and zero usage of water during the production process, the method comprising: providing a synthesis gas (syngas) by the gasification of coal or coal and biomass; subjecting said syngas to Fischer-Tropsch synthesis (FTS) to produce a hydrocarbon product stream; separating said hydrocarbon product stream into gaseous hydrocarbons that have from one to four C atoms (methane, ethane, propane, butane, etc.), which are commonly referred to as (C1-C4) hydrocarbons, and C5+ hydrocarbons used for the production of as liquid fuels; providing an enhanced catalytic dehydrogenation (CDH) process by the injection of a stream of methane gas; subjecting said (C1-C4) hydrocarbon stream to said enhanced catalytic dehydrogenation process to produce hydrogen (H mixing said H
