半焦催化裂解煤热解焦油的研究
Study on the catalytic cracking of coal pyrolysis tar over char
摘要
Abstract
In order to improve the quality of tar,with the usage of a fix-bed reactor, the catalytic cracking effects of coal pyrolysis products in Fugu, Shaanxi are researched under two different modes of action(the mixed pyrolysis and the two-stage catalytic cracking).The results show that after catalytic cracking of coal pyrolysis products the tar yield decreases, while the gas yield increases, especially in the two-stage reactor.When the used catalytic char amount is certain, the highest tar yield is gained at 600 ℃ for the mixed pyrolysis, while the tar yield decreases as the pyrolysis temperature increases for the two-stage catalytic cracking, but the difference becomes smaller with the rise of react tempture.The effect is best when the reaction temperature is 600 ℃ and the char as catalyst is of 20% coal mass for mixed pyrolysis, resulting in the increase of the content of light components in the obtained tar from 52% to 65.5%, and the light tar yield increases from 4.5% to 5.3%, namely by 17.8%.关键词
