摘　　要：比较了环境友好催化剂HY和Hβ分子筛催化萘与长链烯烃(C11、C12混合烯烃)烷基化反应的催化性能,研究结果表明,HY分子筛具有较高的催化活性和烷基化选择性。考察了反应温度、压力、萘与C11/C12烯烃摩尔比、进料空速、催化剂粒度等反应条件对烯烃转化率的影响,在适宜的反应条件(萘与C11/C12混合烯烃摩尔比4/1、反应温度130℃、催化剂粒度20～40目、进料空速10ml/(h·g)、压力1 0MPa)下,长链烯烃的转化率可达85%,单烷基萘的选择性为100%。该催化剂易于再生,可循环使用。The liquid-phase alkylation reactions of naphthalene with long chain olefins (C 11 /C 12 ) on two different molecular sieve catalysts,HY and Hβ were investigated.Molecular sieve HY showed higher activity and mono-alkylnaphthalene selectivity than Hβ Effect of reaction temperature,reaction pressure,naphthalene/olefin/cyclohexane mole ratio,the LHSV and the particle size of HY Molecular sieve catalyst had been studied.Conversion of olefins was over 85%.Mono-alkylnaphthalene selectivity was 100% at typical reaction conditions (naphthalene/olefin/cyclohexane mole ratio,6/1/60;temperature,130 ℃;pressure,1 MPa;LHSV,10 ml/ (h·g); time,6 h).HY molecular sieve catalyst could be easily regenerated,and showed similar rate of olefin conversion as the fresh.
