Process for aromatic type semi regeneration catalytic reforming of coal derived naphtha
摘要
Abstract
The experimental studies of single factor on the semi regenerative catalytic reforming of coal derived naphtha has been made in an adiabatic fixed bed device using new industrial platinum rhenium reforming catalyst(Pt-Re/γ-Al2O3). The process parameters were optimized and analyzed by response surface methodology. Finally,experimental product analyses at optimized process conditions were made.The results show that WA I T(weighted average inlet temperature),P(reaction pressure), and LHSV(liquid hourly space velocity)had a strong influence on the product quality,aromatic yield, and C5+liquid yield of the aromatic type semi regeneration catalytic reforming of coal derived naphtha. The appropriate process parameters intervals were:WAIT 500—520℃,P 1.2—1.6MPa,LHSV 2.0—3.0h–1.The optimal process conditions were determined as follows:WAIT at 516℃,P at 1.4MPa,LHSV at 2.3h–1. Under the optimized process conditions,the yield of aromatics reached 79.81%. In the operating condition intervals of response surface experiments,the order of magnitude of WA I T,P and LHSV on the yield of aromatics was:P>LHSV>WAIT. Compared to petroleum derived naphtha reforming,coal derived naphtha reforming can obtain higher pure hydrogen yield,hydrogen purity,and BTX (benzene-toluene-xylene) yield. The ratios of benzene yield to toluene yield and to xylene yield are approximately 1/3 and 1/2,respectively.关键词
