Process for making combustable gas by external high temperature CO2 and biomass reducing reaction

Abstract

The reduction reaction process of exogenic high temperature CO2 and biomass for preparing combustible gas includes setting biomass into furnace, and spraying high temperature CO2 and combustion promoting water vapor from external burner so as to gasify ligonocellulose and similar biomass into combustible gas with CO and H2 as main components. The said process can produce combustible gas of high heat value and capable of being used as civil fuel and industrial fuel in high gas producing rate, high carbon converting rate and adjustable gas components.

Description

technical field [0001] The invention belongs to exogenous high temperature CO 2 The technical field of producing combustible gas by reduction reaction with biomass. Background technique [0002] At high temperature, the thermochemical process of converting biomass, such as wood or other carbon-containing solid materials, into combustible gases using gasification agents is called gasification, that is, the thermochemical process of converting solid or liquid fuels into gaseous fuels. process. In the gasification unit, free or bound oxygen chemically reacts with the carbon in the fuel to produce combustible gases. Using gasification to convert woody raw materials, crop stalks or organic industrial waste into gaseous fuels is not only of great significance in saving energy, but also in protecting the environment and preventing pollution. [0003] Biomass gasification is the process of using oxygen or oxygen-containing substances in the air as ...

AI Technical Summary

Problems solved by technology

The common problem of self-heating biomass gasifiers is that it is difficult to establish a balance mechanism of oxidation and reduction reactions to maintain stable reaction conditions and reaction beds, and it is also difficult to adjust the gasification rate by reasonably controlling the amount of air entering the gasifier. furnace load
