It was found that chromium decreases the specific surface area but increases the acidity, turning MCM-41 into an active and selective catalyst for ethylbenzene and toluene production. The coke produced on the catalyst is hydrogenated and mainly located outside the pores and thus can be easily removed. The catalyst is more active and selective than mordenite, a commercial catalyst, and thus more promising for commercial applications.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-12-12T12:52:44Z No. of bitstreams: 1 23034.pdf: 276220 bytes, checksum: 727c2d2f46d69ff7be8405058563ef97 (MD5)Made available in DSpace on 2011-12-12T12:52:44Z (GMT).
