摘要 在全面考察与研究了WO_3/SiO_2丙烯歧化催化剂的催化及物化特性之后,本文考察了在丙烷-丙烯混合原料中丙烷对丙烯歧化催化剂转化率、选择性等的影响,分析了其原因。其结果为丙烷-丙烯混合气作为歧化原料,提供了可靠依据。 Upon the successful development and study of the heterogeneous catalyst WO_3/ SiO_2 for pure propylene disproportionation, this paper studied the influence of propane on the disproportionatioB reaction when C_3~=-C_3~0 mixture was used as feedstock instead of pure propylene. The experimental results show that at low pressure range and identical reaction conditions for feedstocks with different C_3~0 contents the reaction conversion decreases and selectivity increases with increasing C_3~0 content. This is confirmed by the Rideal model, which is based on the hypothesis of the interaction betweem the adsorbed molecule and a gas-phase molecule. A satisfactory explanation is presented.
