Abstract
Provided herein are catalyst supports, catalyst systems, and methods for making catalyst supports, catalyst systems, and performing chemical reactions with the catalyst systems. The catalyst supports include a zeolite and a binder including non-sodium counterions, such as ammonium counterions and/or potassium counterions. The catalyst systems include the catalyst supports and a catalytic material. The catalyst systems may be used to perform chemical reactions, including reactions of one or more hydrocarbons.
Claims19
A process for making a catalyst system, the process comprising:
- contacting a zeolite and a binder to form a mixture, wherein the zeolite comprises a non-zeolitic molecular sieve with intermediate or large pores, and wherein the binder comprises a colloidal silica including potassium counterions, ammonium counterions, or a combination thereof, and substantially no sodium counterions;
- extruding and/or shaping the mixture to form a dimensioned mixture;
- drying the dimensioned mixture to form a substantially dried dimensioned mixture;
- calcining the substantially dried dimensioned mixture to produce a catalyst support;
- adding one or more Group VIII metals and one or more halides to the catalyst support to form a metalized and halided catalyst support;
- and
- drying and calcining the metalized and halided catalyst support to form the catalyst system.
