低温煤焦油加氢制备清洁燃料油品中试试验研究
Pilot-scale study of upgrading a low temperature coal tar distillate for the production of clean fuels
摘要
Abstract
The hydrogenation of low temperature coal tar(LTCT)was carried out in a four-stage fixed bed reactor with various catalysts combination on a pilot scale over 400h to produce clean liquid fuel. Meanwhile,the impacts of temperature,pressure and liquid hourly space velocity(LHSV)on light oil yield,heteroatomic removal were determined combined with the catalyst characterization results. And the properties and chemical composition of intermediate and final products,gasoline and diesel were investigated. Moreover,the stability of the catalyst and mass balance were analyzed. The results showed that the yield of gasoline and diesel can reach 33.5% and 64.2%,respectively,and capable of removing sulfur and nitrogen to less than 10μg/g though decreasing LHSV and increasing the temperature; the product oil was gradually cleaned,and after hydrotreating,decalins,tetralin and indenes and alkyl-cycloalkanes(CA)were the main hydrogenated products; in addition to RON (Research Octane Number),other indicators of gasoline products are in line with national specifications,diesel fraction meet the national specifications. Furthermore,the catalyst used throughout the reaction system has a uniform and good stability,and there is an acceptable error of about 1.32% between the inlet and the outlet.关键词
