Abstract

The present invention is characterized by that it adopts the high temperature produced by adding proper quantity of industrial pure oxygen and small quantity of hot gas into uncooled hot gas to make them produce reaction to make the tar, naphthalene, benzene, organic sulfur and ammonia, etc. being in gas be cracked and converted into CO, H2, N2 and H2S, and can remove H2S at normal temperature. Said method can be used for purifying coke oven gas and non-anthracite gas, can make coke oven gas be raised by about 10%-25%.

Description

Technical field:

[0001] The invention belongs to the field of gas purification in chemical engineering, in particular to a method for purifying pitch, tar, naphthalene, benzene, benzene, cyanide and the like in coal gas produced from coal coking and non-anthracite. Background technique:

[0002] The uncooled coke oven gas produced during the coal coking process is usually called raw coal gas. The current purification method is to spray and circulate ammonia water to condense the high-temperature tar mist in the raw coal gas into liquid tar when the raw coal gas enters the gas collection pipe. , coke oven gas is separated with circulating ammonia water, and low temperature tar and naphthalene, benzene, ammonia, hydrogen sulfide, cyanide, etc. are separated from coke oven gas by physical or chemical absorption at room temperature. Due to the complex composition of coke oven gas in the traditional coke oven gas purification process, in order to recover as many chemical products...
