At present, tar generated in most of coal pyrolysis processes has the shortcoming of having high yield of heavy components. Due to the heavy components in the tar, the grade and the value of a tar product are reduced and a series of problems of dust entrainment, pipeline blockage, difficulty in high-temperature air-solid separation, high subsequent treatment cost and the like can be caused in the pyrolysis process due to high viscosity of the heavy components. Pyrolysis tar can be lightened by adopting a process in which the direct catalyzing and conditioning are carried out on high-temperature pyrolysis gas. The tar lightening can be remarkably facilitated by an Al-Mg-Ni-O catalyst provided by the invention. The catalyst comprises the following components by weight percent: 1%-10% of NiO, 10%-20% of MgO and the balance being a gamma-Al2O3 carrier. After the high-temperature pyrolysis coal gas is catalyzed and reformed by the catalyst, the contents of the heavy components in the tar product are reduced and the yields of BTX (benzene toluene xylene) and PCX (phenol cresol xylenol) are greatly increased. Meanwhile, the catalyst has the advantages of low price, good heat stability, carbon deposition resistance and the like.
