摘要（英）：
The invention discloses a microwave pyrolysis catalyst and a method for preparing the same. The microwave pyrolysis catalyst comprises, by total weight, 5%-10% of catalysis components and 90%-95% of wave absorbing component. The catalysis components are AB type metal mixtures, and the wave absorbing component is activated semi-coke powder. The particle sizes of the catalysis components rangefrom 0.2 micrometer to 0.5 micrometer, and the particle sizes of the wave absorbing component are smaller than 76 micrometers. The A in the catalysis components represents a type or a plurality of types of iron, copper, cobalt, nickel and molybdenum, and the B in the catalysis components represents a type or two types of oxygen and sulfur. The microwave pyrolysis catalyst and the method have theadvantages that activated semi-coke is used as a carrier, metal compounds with functions of increasing the yield of tar and improving the quality of the tar are loaded by the aid of ultrasonic impregnation processes, accordingly, the inexpensive microwave pyrolysis catalyst can be prepared, the yield of the tar can be effectively increased, the quality of the tar can be effectively improved, the cost of the microwave pyrolysis catalyst can be reduced to a great extent, and introduction of excessive impurities can be prevented; utilization ways for the semi-coke powder can be expanded, and accordingly the microwave pyrolysis catalyst and the method have important significance in technical progress of the semi-coke industry in China and classified, efficient and clean utilization of existingcoal resources.
