A STUDY OF CATALYST FOR n-PENTANE ISOMERIZATION

Ming Lu

Abstract

Effects of contents of Na, Pt and Zr, and preparation of PtZrO2/HM catalyst on npentane isomerization reaction were investigated in a continuous microreactorchromatographic unit A mathematical orthogonal experimental method was used to obtain an optimum reaction conditions: t=275?℃, p=15?MPa, WHSV=125?h-1, H2/C05=20 (mole ratio) At the optimum conditions, PtZrO2/HM catalyst achieved that npentane conversion is 6988w%, isopentane yield is 6768w%, isopentane selectivity is 9685w%, yield of liquid product is 9780w%
