Thermo-catalytic pyrolysis of refuse derived fuels with different catalysts had been conducted in a two stages process due to its important potential value as fuel. The first stage was a pure thermal pyrolysis in a horizontal tubular reactor with feed rate of 0.5kg hourly. The second stage was a semi-batch process in the presence of catalysts. Results showed that the tested catalysts significantly have affected the quantity of products. E.g. gas yield could be increased with 350% related to the catalyst free case using ZSM-5, while that of pyrolytic oil was 115% over Y-zeolite. Gases consisted of mainly CO and CO(2) obtained from the tubular reactor, while dominantly hydrocarbons from the second stage. Ni-Mo-catalyst and Co-Mo-catalyst had shown activity in pyrolytic oil upgrading via in-situ hydrogenation-dehydrogenation reactions. Sulphur, nitrogen and chlorine level in pyrolytic oils could be significantly declined by using of catalysts.
由于废燃料作为燃料具有重要的潜在价值，因此对其进行了不同催化剂的热催化热解。第一阶段是在水平管式反应器中以 0.5kg/小时的进料速率进行纯热解。第二阶段是在催化剂存在下的半分批过程。结果表明，测试的催化剂对产品的数量有显著影响。例如，使用 ZSM-5 可使气体产率增加 350%，与无催化剂的情况相比，而使用 Y-沸石可使热解油增加 115%。从管式反应器中得到的气体主要由 CO 和 CO(2)组成，而第二阶段主要由碳氢化合物组成。Ni-Mo 催化剂和 Co-Mo 催化剂通过原位加氢-脱氢反应显示出在热解油升级中的活性。通过使用催化剂，可以显著降低热解油中的硫、氮和氯水平。
