摘　　要：在500℃下将不同比例的稻壳与轮胎混合物在SBA-15,Mo/SBA-15和Co/SBA-15三种催化剂下共热解,研究了不同催化剂及不同比例稻壳与轮胎的混合物对热解油产率、热值和比重等的影响,并对热解油元素组成进行分析.结果表明,随着轮胎比例的增大,热解油比重和粘度有所降低;当稻壳与轮胎比例为75:25时,Co/SBA-15对油中氧含量的降低和氢含量的提高表现出较好的效果.The mixtures of rice husk and tyre with different weight ratios were co-pyrolyzed with different catalysts （SBA-15, Mo/SBA-15 and Co/SBA-15） at 500℃. The influence of catalysts and different weight ratios of rice husk to tyre on pyrolytic oil yield, high heating value （HHV） and density was investigated; and the elementary composition of oil is analyzed. The results show that, there is a decrease in the pyrolytic oil density and viscosity with increase of tyre proportion in the mixtures. The effect of Co/SBA-15 is better in decreasing the percent of oxygen and increasing the percent of hydrogen than those of the other two catalysts when the ratio of rice husk to tyre is 75： 25.
