摘要
Abstract
K2CO3 catalytic gasification of Neimeng brown coal was studied in a fixed bed reactor. The effects of catalyst loading, temperature, gasification agents, such as H2O and H2, and partial pressure of H2O on the carbon conversion and reaction rate were investigated. The results showed that K2CO3 could accelerated the rate of coal-steam gasification obviously, and the carbon conversion reached 70% with the addition of only 10% K2CO3 by mass at 700℃, while H2 inhibited the coal-steam gasification seriously. A kinetic reaction equation was proposed based on an n order and Langmuir-Hinshewood expression by evaluating the carbon conversion behavior. The gasification activity significantly increased with steam partial pressure. In the n order expression, the order nwas 0.87 and the activation energy was 169.2kJ/mol, and, in the L-H expression, the activation energy was 121.9kJ/mol.关键词
