A polygeneration system of coal or biomass gasification and methane cracking

Abstract

A polygeneration system for coal or biomass gasification and methane cracking, including a material bin, a gasifier, a steam generator, a first gas separator, a methane cracking furnace and a second gas separator, wherein the material bin and The entrance of the gasifier is connected, the outlet of the gasifier is connected to the steam generator and the methane cracking furnace respectively, the steam generator is connected to the first gas separator, and the material bin is also connected to the second gas separator; coal or biomass gasification is used The reaction process conditions are used to achieve the preparation of the catalyst, and at the same time, the industrial chain is extended with the help of "catalyst preparation-catalyst use", thereby constructing coal or biomass gasification (preparation of porous carbon-supported metal catalysts) and methane cracking The series or polygeneration of technological processes (using porous carbon-supported metal catalysts) can help achieve large-scale production and save costs. The invention has simple design, low investment cost and is convenient for industrial application.

Description

technical field [0001] The invention belongs to the field of energy and chemical industry, and in particular relates to a polygeneration system of coal or biomass gasification and methane cracking. Background technique [0002] my country's energy situation of "rich in coal, poor in oil, and low in gas" determines that my country will continue to use coal as the main body of energy consumption for a long time in the future. Among them, the coal gasification process is one of the main ways to produce synthesis gas products. It converts solid coal into gaseous synthesis gas through the gasification process. Syngas can be further converted into advanced fuels or chemicals by Fischer-Tropsch synthesis. Therefore, the coal gasification process is often combined with synthetic ammonia, synthetic methanol and other processes to achieve polygeneration and large-scale economic benefits. [0003] Biomass is an important renewable energy source, which is widely distributed and has a ...
