摘要
Abstract
The industrial application of the BHAT-01 catalyst for the transalkylation of benzene and heavy aromatics in the disproportionation unit of the aromatics complex unit in PetroChina Liaoyang Petrochemical Corporation Branch was introduced. The application indicated that the catalyst had high performances in producing toluene and C8 aromatics from benzene and heavy aromatics. Under the following conditions of reaction temperature 360℃,pressure of high pressure separator 2.7 MPa, WHSV 1.8 h-1 and mole ratio of H2to liquid feedstock 7.5,the benzene conversion,heavy aromatics conversion,and total yield of toluene and C8 aromatics were 35.99%,74.26% and 96.34%, respectively. The catalyst can also be used in the existing toluene disproportionation and transalkylation process,and its performances are even better than those of the existing catalyst. Under the following conditions of reaction temperature 355℃,pressure of high pressure separator 2.7 MPa,WHSV 2.0 h-1 and mole ratio of H2to liquid feedstock 5.7, the total conversion of toluene and heavy aromatics, and the total yield of benzene and C8 aromatics were 47.22% and 94.98%,respectively.关键词
