A macroporous sulfonic acid resin is a very important class of solid acid catalyst, having a non-corrosive , and the advantages of no environmental pollution , many reactions catalyzed olefin , such as etherification, alkylation , etc. , and a macroporous sulfonic acid resin in the olefin have good catalytic activity in the alkylation reaction with the thiophene sulfides . This paper examines four different manufacturers macroporous sulfonic acid resin : NKC- 9 , CT -175 , D005 - II and LSI - 600 , thiophenes sulfides and olefin alkylation reaction in the catalytic properties . Using the batch-type reactor, the material agent than by changing the reaction temperature , reaction time and raw material composition and other conditions , the activity of the four resins were evaluated . Experimental results indicate that the reaction temperature of less than 90oC , the catalytic activity of the four resins are enhanced as the temperature increases , but drawn NKC-9 is superior to the catalytic activity of the other three resin . While optimizing a suitable alkylation reaction conditions : atmospheric pressure , 90oC, material agent volume ratio of 15:1 . Under the reaction conditions , the total 92.32% of the sulfide sulfur can occur the alkylated sulfur transfer reaction , and also has a good role in the transfer of four resin the low boiling mercaptan FCC gasoline , mainly because macroporous sulfonic resin existing alkylation catalytic performance , have a good adsorption effect . While using the GC-MS method investigated NKC-9 selectivity found NKC-9 is mainly suitable for catalytic thiophenes sulfides and C4 , C5 olefin alkylation reaction . Further, use of the analysis method such as XPS , the chemical method is the inactivation of the four resins were studied , and found the FCC gasoline in the alkaline nitride affect macroporous sulfonic acid resin main reason of deactivation , so the raw material for adsorption four stability of the resin is very good when the pretreatment is necessary ; as raw material for the alkylation reaction and adsorption after pretreatment of FCC gasoline . In addition , the use of the reactor of the FCC gasoline sulfide conversion rate study . The results showed that under the reaction conditions of atmospheric pressure , 90oC, coat agent volume ratio of 15:1 , the alkylation of the various sulfides and thiophenes olefin reactive sequence is: 2 - methyl - thiophene- GT ; 3 - methylthiophene the gt; 3,4 - dimethyl- thiophene GT ; 2,3 - dimethyl- thiophene gt ; 2,4 - two methyl thiophene gt ; thiophene GT ; 2 or 3 - ethylthiophene GT ; 2,3,4 - trimethyl- thiophene.
