A METHOD AND A SYSTEM FOR SYNTHETIC LIQUID FUEL PRODUCTION BY INDIRECT GASIFICATION.

摘要

A novel approach is proposed for applying external renewable energy in the form of high temperature geothermal steam, hydro-electricity, and/or heat derived from nuclear reactors to carbon containing feedstock (for example biomass waste paper or coal) in a large scale well insulated Fischer-Tropsch process to produce liquid fuels of high energy content, and by-products for industrial production of e.g. gypsum or cement and combustion of tail gas in the gasifier to produce additional heat. A nuclear reactor is employed to superheat steam up to temperatures above 2.500°C, at which H2 and O2 are separated and then directed to the gasifier in the proportion required for the conversion of said syngas components into liquid fuels by the Fischer-Tropsch synthesis. The heat is recycled wherever possible and thus maximum energy efficiency and maximum material utilization from the feedstock and the geothermal steam are simultaneously achieved. Energy from high temperature steam is recycled in the form of electricity by a generator to electrical heating elements and/or district heating. A system for performing the process is also provided.
