Effect of iron-based catalysts on hydropyrolysis behavior of coal

Abstract

This work determines the effect of hydropyrolysis of coal through a stabilizing reaction by impregnation method using catalysts such as Fe(NO3)3, FeCl3, FeSO4·(NH4)2SO4·6H2O. If you add three kinds of catalyst the hydropyrolysis change degree are increases. Adding semi-iron ammonium sulfate of 5 % the tar yield increased from 14.3 % without catalysts to 17.9 %. The preservation of ammonium radical gives the possibility to increase the formation of coal tar and degree of coal pyrolysis.
