为了提高热解过程中油的回收率，在管式炉反应器中采用分子筛和含铁分子筛催化剂对含油污泥进行了反应。采用水热法制备了催化剂，并用各种表征方法对催化剂进行了表征。试验样品的结果表明，延长时间可以显著提高出油率。在初始阶段，随着催化剂用量的增加，采收率增加，而在后期阶段，采收率降低。此外，温度越高产油量越高，同时分子筛催化与污泥的最佳配比为0.035。研究表明，含油回收率可达85.52%。催化作用对含油污泥样品中油收率的影响表现为分子筛和含铁分子筛的降序。
To raise the recovery of oil during pyrolysis, reactions were performed on oily sludge using catalysts such as a molecular sieve and an Fe-containing molecular sieve catalyst in a tubular furnace reactor. The catalysts were prepared through hydrothermal method and characterized by various characterization methods. The results of the sample for the test have shown that more time could significantly increase the oil yield. The rate of oil recovery was increased with the increase of the catalytic in the initial phase and decreased at the back of the stage. In addition, higher temperature contributed to higher oil production, and at the same time the optimal ratio of molecular sieve catalytic to sludge was found to be 0.035. Research has revealed that the content of oil recovery rate could reach up to 85.52%. The effects of catalytic on the recovery improve rate of oil in oily sludge samples presented the following decreasing order of the molecular sieve and the Fe-containing molecular sieve.
