Abstract In the pyrolysis process, the removal and transformation of tar is the key technology to realize the solid waste resources and energy utilization. ICatalytic cracking is an effective way to remove tar, which can transform tar into high-value gas products. In this paper, solid waste rice husk is taken as the research object and raw material, the rice hull char-based catalyst materials were prepared by wet impregnation method, and used the materials in the pyrolytic-cracking experiment of rice husk to improve the quality of produced gas. The physical and chemical properties of the materials were detected by scanning electron microscopy ( SEM),X-ray energy spectrum ( EDS), X-ray diffraction ( XRD ) and Brunauer-Emmett-Teller ( BET) to analyze the properties of single metal and bimetal materials. In the pyrolytic-cracking reaction of rice husk, the influence of reaction temperature on tar conversion and gas yield was analyzed, the generated gas composition and content were detected, and the influence of the mass ratio of raw material and catalyst material on the generated gas was explored. Meanwhile, the reuse of catalyst materials was tested and analyzed. The results showed that, the addition of rice husk char-based material had a significant improvement on the composition of generated gas during pyrolysis. In the generated gas, the content of hydrogen and carbon monoxide increased, while the content of carbon dioxide decreased, and the molar ratio of syngas in the gas could reach 80%. An appropriate increase in the amount of catalysts can improve the gas yield in the pyrolytic-cracking reaction. When the mass ratio of raw materials and catalysts is approximately 1 :1, the gas yield basically reaches an equlibrium state. In this paper, the prepared rice husk char-based materials showed good performance in removing tar and improving the quality of gas products , the one-step pyrolytic-cracking reaction effectively improved the quality of generated gas by pyrolysis,which provided basic data and new materials for the study on the preparation of high-quality gas by pyrolysis.
