- Abstract
In order to study the effect of pretreatment on non-caking coal blending and coking,a small coke oven was used in coal blending and coking test. The differences between non-caking coal and pretreatment non-caking coal were studied,which included metamorphic degree and bonding properties of blending coal,coke strength and coke optical tissue. The results indicated that the vitrinite maximum reflectance increased from 0. 46% to 1. 20% because of the decrease of oxygen-containing functional groups. The pretreatment didn't make the non-caking coal more sticky and the caking property of blending coal fell slightly. The small coke oven test showed that,the barrate strength of coke prepared from pretreatment non-caking coal increased by 0. 5%,the post-reaction strength decreased by 1%. The barrate strength and post-reaction strength of coke prepared from non-caking coal decreased by 1% and 4% respectively. The pretreatment increased the medium grain mosaic structure and the anisotropic index increased by 7. 7% to 15. 8%.
