Abstract
Disclosed is a method for preparing a catalyst for a gasoline reaction of dimethyl ether that includes reacting a silica source, an aluminum source, and a structural derivative to synthesize a zeolite sol, mixing an alcohol with an organic template to form an emulsion phase, and adding a zeolite sol to the emulsion phase to perform a reaction.
Claims7
A method for preparing a catalyst comprising a zeolite for a gasoline reaction of dimethyl ether, comprising:
- reacting a silica source, an aluminum source, and a structural derivative to synthesize a zeolite sol;
- mixing an alcohol with an organic template to form an emulsion phase;
- and
- adding a zeolite sol to the emulsion phase to perform a zeolite synthesis reaction to synthesize a zeolite;
- wherein the structural derivative is a nitrogen-containing heterocyclic compound including pyrrolidine, piperidine, or a combination thereof;
- wherein the organic template comprises cetrimonium bromide (CTAB), sodium dodecyl sulfate, ammonium lauryl sulfate, or a combination thereof;
- and
- wherein the zeolite comprises a ferrierite (FER) structure and a ZSM-5 structure.
