地沟油催化裂解产物的分析

摘要：地沟油中 S、N 元素含量很低，可作为一种可再生的清洁能源。我国石油消费对外依存度高达 60%，为缓减乃至摆脱我国对国外石油资源的依赖，研究发展以地沟油油为原料生产生物燃料新工艺，其社会价值和效益与环境效益都是巨大的。本课题以地沟油为原料考察其催化裂解产物的组成和分布情况。实验装置为自制微型固定床反应器，通过改变各种工艺操作参数实现对其的影响，再通过减压蒸馏与质谱分析检测分析产物的分布和组成。实验结果表明，使用清江石化 2014 年的三旋催化剂，以新制 Al（OH)3 为粘合剂，制得氧化铝质量分数为 10%的纯催化剂在反应温度为 520℃，流速为 1 ml/min，汽、柴油的收率最大。催化反应温度越高，气相收率越高。气相中，乙烷、丙烯和丙烷占总气相的 95%左右，其中乙烷 75%-85%。75436

Abstract ： The waste oil is a kind of clean and renewable resources which contains little the elements of S and N。 The crude oil consumption external dependence is as high as 60% in China。 It is necessary to research and develop a new technology for producing bio-fuel by using waste oil as raw material，in order to reduce and even get rid of our country's dependence on foreign oil

resources。 Both societal and environmental benefit would be notable。

In this paper, the composition and distribution of catalytic pyrolysis products were investigated by using waste oil as raw materials。The experimental device is a self made micro fixed bed reactor, and the influence of various process parameters was changed, then the distribution and composition of the products were analyzed by vacuum distillation and mass spectrometry。 The results of experiments showed that the use of Qingjiang petrochemical in 2014

three spin catalyst, the new system Al(OH)3 as binder, the alumina quality score of 10% of the pure catalyst reaction temperature of 520 ℃, the flow rate of 1 ml/min, gasoline, diesel oil was the most yield。The higher the catalytic reaction temperature,the higher the gas phase yield。

Ethane,propylene and propane accounted for about 95% of the total gas phase in which ethane accounted for 75%-85% in the gas phase。
