炭化温度对红柳林煤温和液化-炭化耦合转化产物的影响
Effects of carbonization temperature on the products from integrated mild-liquefaction and carbonization process of Hongliulin coal
摘要
Abstract
The integrated mild-liquefaction and carbonization experiments of Hongliulin coal were conducted at 430-600℃, and distributions and physico-chemical properties of the obtained products were investigated. The results show that the yields of semi-cokes, organic liquid products and n-hexane soluble organic products were up to 40. 64%-53. 02%, 30. 89%-36. 98% and 29. 74%-33. 28%, respectively. The increasing carbonization temperature in the relatively low temperature range was favorable for the elevated yield of n-hexane soluble organic products, while at relatively high temperature presenting an opposite one. The semi-cokes obtained at 430℃ presented a strong caking property, while those at 550℃ showed no caking property, and the content of their volatile matters decreased to about 10%. It is suggested that the produced semi-coke could be directionally utilized as blending coal in coking or smokeless fuel by adjusting carbonization temperature.关键词
