Gasification-reforming transformation reformer of carbonic materials and method of preparing hydrogen-rich syngas

Abstract

The invention discloses a gasification-reforming transformation reformer of carbonic materials. The gasification-reforming transformation reformer is characterized by comprising a gasification reaction chamber, reforming equipment, a transformation reaction chamber and a syngas output pipeline, wherein the gasification reaction chamber is provided with at least one nozzle; the reforming equipment is arranged at the output end of the gasification reaction chamber; the transformation reaction chamber is arranged at the output end of the reforming equipment; and the syngas output pipeline is connected with the output end of the transformation reaction chamber. The invention further discloses a method of preparing hydrogen-rich syngas. The method comprises the following steps: generating a gasification reaction (first reaction) on a carbonic material and an oxidant in the gasification reaction chamber to generate a syngas containing main ingredients of carbon monoxide and hydrogen under a high-temperature high-pressure environment, reforming the gasified syngas to proper temperature and ingredients through a reforming agent, generating a transformation reaction (second reaction) on the syngas in the transformation reaction chamber to fully generate carbon monoxide transformation reaction so as to improve the transformation rate of the carbon monoxide, thereby greatly reducing the carbon monoxide content in the syngas and increasing the hydrogen content to prepare hydrogen-rich syngas.

Description

technical field [0001] The invention relates to a carbon-containing material gasification-reforming conversion converter and a method for preparing hydrogen-rich synthesis gas. Background technique [0002] The gasification technology of carbonaceous materials such as coal, biomass, and petroleum coke is the basis for the development of process industries such as coal chemicals, liquid fuels, combined cycle power generation, polygeneration, and hydrogen production, and is the key technology, common technology, and leader of these industries technology. [0003] The carbonaceous material gasification process can be divided into three types: moving bed, fluidized bed and entrained bed according to the movement state of the material in the reaction chamber. Compared with the other two processes, the entrained flow bed has the advantages of large processing capacity of single furnace gasification reaction chamber, wide adaptability of coal types, and high carbon conversion rate...
