摘要：In this work, a trifluoromethanesulfonic acid (TFOH) modified clay (TFOH-Clay) was developed for the removal of trace olefins in heavy naphtha. 5%TFOH-Clay can effectively improve the reaction activity, which can increase the conversion rate from 61.12 to 87.82%. Through the results of elemental analysis, it can be found that TFOH can be loaded on the clay, the actual load capacity of 5%TFOH- Clay is 4.55%. As a result of acid analysis, the Bronsted acid of the catalyst continuously increases with the increase of TFOH, which is beneficial to improve the reaction activity. The BET results show that loading TFOH will reduce the specific surface area of the catalyst, which is negative to the progress of the reaction. In order to balance the mutual influence of the both, the optimal load of TFOH is 5%.
