Process of co-producing high clean fuel by adding hydrogen to coal gasifying, power plant or other industrial waste gas

Abstract

The present invention relates to process of coal gasifying and compounding CO2 from industrial waste gas with H2 to produce clean fuel. Normally, coal gas contains CO in about 65 % and H2 in about 30 %. Industrial waste CO2 is used in producing O2 and CO or compounding H2 to produce clean fuel for generating electricity or producing chemical products, etc. The present invention can save coal resource and reach zero exhaust of harmful gas. Or, coke oven gas may be used in preparing high H2 and low CO gas, and blast furnace gas may be used in preparing high CO and low H2 gas via compounding with H2. The gas materials entering the Linda low temperature synthesis tower or other tower has the proportion computer controlled in producing clean fuel.

Description

technical field [0001] The invention relates to coal gasification and the mixing of carbon dioxide from industrial waste gas into hydrogen to produce clean fuel in a high cycle, which can save 50% of coal resources. In addition, no matter whether this clean fuel is used for clean power generation, to produce high-clean vehicle fuel, or for residential and industrial use, or for the production of chemical products, etc., it can achieve zero emission of harmful gases. Background technique [0002] 1. Traditional coal power generation technology in various countries in the world [0003] The traditional coal direct combustion power generation technology in various countries in the world has a utilization efficiency of only about 30% per ton of coal, and the remaining 70% is mixed with oxygen to produce about 2 tons of carbon dioxide, sulfur dioxide and nitrogen oxides. Our country uses the traditional process of coal to directly burn power generation, smelt coke, smelt steel, ...

AI Technical Summary

Problems solved by technology

Only a small part of the 100 billion cubic meters of coke oven gas emitted in my country every year is simply utilized, and the utilization efficiency is very low

Since the coke oven gas itself contains H 2 About 60%, containing about 17% of CO, so simple utilization still wastes about 26% of H 2
