摘 要: | 以有机氟化物三氟一氯甲烷对现用国产工业丝光沸石催化剂进行改性处理。在微反中,以非临氢与临氢条件对甲苯歧化与甲苯-C_9芳烃烷基转移反应中的四个主反应进行考察,并在100克放大装置上考察了甲苯歧化反应效果。用IR和TPD考察了改性前后催化剂的酸性条件。改性后的丝光沸石催化剂可较大幅度提高C_8芳烃收率,而且催化剂的热稳定性提高。

Study of Organofluoride Modified Industrial Mordenite Catalyst for Toluene Disproportionation and Transalkylation |
| |
Abstract: | A local industrial mordenite catalyst is modified by organofluoride.The effect on the four major reactions of toluene disproportionation and toluene-C_9 aromatic transalkylation is investigated in a microreactor with or without addition of hydrogen gas. Toluene disproportionation is also observed in a scale-up reactor with 100g catalyst. The acidity change in the catalyst after modification is measured by IR and TPD. Modified catalysts are more stable, and can greatly increase the yield of C_8 aromatics. |
