Function of metal oxide and complex oxide catalysts for hydrocracking of coal

摘要: Abstract The catalytic activity and selectivity of metal oxides complex for the liquefaction bituminous coal lignite are reviewed first discussed in connection with surface properties catalysts. However, it has been realized that functions catalysts not fully understood. Thus, present work, hydrocracking diphenylmethane, diphenyl ether, benzyl phenyl ether as model compounds coal, dehydration 2-propanol a test reaction cracking ability (acidity) catalyst, hydrogenation naphthalene catalyst were studied by employing various oxide It concluded acidic property plays an important role CC bond cleavage, while is CO cleavage. This conclusion was found to be agreement results Akabira (carbon content: 83.0%) Big Brown 72.3%).
