Abstract

The invention relates to a coke for gasification and a preparation method thereof, for solving the problems of a low tar yield, a low crude benzene yield and a low coal gas yield of the existing coal gasification. The coke for gasification disclosed by the invention is mainly composed of combustible volatiles, ash, M40 and water; the preparation method comprises the following steps: 1, crushing and mixing; and 2, coking. The coke for gasification and the preparation method thereof disclosed by the invention are used for coal gas production adopting a manner of coke gasification.

Description

technical field [0001] The invention relates to a coke for gasification and a preparation method thereof. Background technique [0002] Coke is produced from a variety of coals through high-temperature coking. It is mainly used in blast furnace ironmaking and blast furnace smelting of non-ferrous metals such as copper, lead, and zinc. It acts as a reducing agent, heating agent, and material column skeleton. Coke reactivity refers to the ability of coke to chemically react with carbon dioxide, oxygen and water vapor. The unit mass of sample with CO in unit time 2 The mass loss of carbon after the reaction is a quantitative concept of coke reactivity. Gasification coke requires low ash content, high ash melting point, appropriate and uniform agglomeration, but although the existing metallurgical coke can be used as gasification coke, due to the limitation of coking coal resources and prices, metallurgical coke is generally not used for gas production.
