文摘

Co promoted Mo/β catalyst has showed superior catalytic performance in hydrocracking of model compounds as well as crude pyrolysis fuel oil into BTX. Catalysts and reaction parameters optimization in hydrocracking of tetralin helps to conduct the efficient hydrocracking of PFO into BTX. Surface and morphological properties in CoMo/β catalyst was observed to be varied with the loading of Co, and it could strongly affect their catalytic activity. Along with the superior catalytic activity, CoMo/β catalyst provided long term stability in continuous flow reaction without any significant deactivation.
