Influence of coke on the aromatization of 3-carene in the vapour phase over zeolites

, 2001
264-269Conversions of 3-carene to cymenes over Na13X, NaY and NaZSM-5 are less than over NaH13X (29% proton exchange), NaHY (33% proton exchange) and NaHZSM-5 (35% proton exchange).

Alkylation of toluene with n-propanol over modified zeolites

, 1998
69-73The reaction of alkylation of toluene with n-propanol has been carried out over HY, LaY, CeY, CrY, LaKY, HZSM-5 and LaZSM-5 zeolites. The yields of cymenes obtained are 35-68 wt% with high selectivity.

Reaction Mechanisms of the Zeolite-Catalyzed Transformations of C9 Alkylaromatics

, 2017
DoctorTransformations of alkylaromatic hydrocarbons are the “heart” of the industrial petrochemistry using zeolite catalysts as the most important large-scale catalysts. For example, m-xylene isomerization and transalkylation of 1,2,4-trimethylbenzene (1,

Study of the process of production of biofuels through pirolysis of tire waste

, 2019
In this study, the pyrolysis process of waste tires was analyzed in the laboratory and pilot scales. In the lower scale, the temperature variation, the type of catalyst commercially obtained (CaCO3, Na2CO3 and Ca(OH)2), the type of catalyst synthesized /
