不同金属化合物催化呼和浩特煤加氢气化实验研究
Experimental study on Hohhot coal hydrogasification catalysed by different metal compounds
摘要
Abstract
The catalysis of K2CO3, Na2CO3, Ca(OH)2 and Ni(NO3)2on the hydrogasification of Hohhot coal was studied in a pressurized fixed-bed reactor, in which the effects of temperature were investigated. The experimental results show that different kinds of metal have a significant difference in the catalysis to the hydrogasification reaction, and the order of catalytic activity is as follows: K > Na> Ni > Ca. Compared with the non-catalytic coal hydrogasification, the temperature of hydrogasification catalysed by K2CO3 is dropped by more than 150 under the same carbon conversion at the same time and reduced about 150 ℃ by Na2CO3 and more than 50 ℃ by Ni(NO3)2. However, the adding of Ca(OH)2 even decreases the observed carbon conversion due to the sorption of Ca( OH)2 for CO2 produced. The SEM and BET results show that coal samples loaded with different metal compounds catalysts have different surface morphologies and pore structures as well.关键词
