Abstract
Catalysts and method of preparing the catalysts are disclosed. One of the catalysts includes a zeolite support, a Group VIII metal on the zeolite support, and at least two halides bound to the zeolite support, to the Group VIII metal, or to both, and can have an average crush strength greater than 11.25 lb based on at least two samples of pellets of the catalyst measured in accordance with ASTM D4179.
Claims20
A catalyst comprising:
- a zeolite support,
- wherein the zeolite support comprises a KL-zeolite bound with silica and a first amount of fluorine;
- platinum supported by the zeolite support;
- chlorine supported by the zeolite support;
- and
- a second amount of fluorine supported by the zeolite support,
- wherein an average crush strength of the catalyst is greater than 12 lb based on at least two samples of pellets of the catalyst measured in accordance with ASTM D4179.
4 more elements
A catalyst prepared by a process comprising:
- calcining an extruded base to form a calcined extruded base, wherein the extruded base comprises a KL-zeolite and silica binder;
- contacting the calcined extruded base with a first fluorine-containing compound to form a fluorinated calcined extruded base;
- washing the fluorinated calcined extruded base to form a washed fluorinated calcined extruded base;
- drying the washed fluorinated calcined extruded base to form a dried washed fluorinated calcined extruded base;
- calcining the dried washed fluorinated calcined extruded base to form a bound zeolite support;
- and
- contacting the bound zeolite support with platinum-containing compound, a chlorine-containing compound, and a second fluorine-containing compound,
- wherein the first fluorine-containing compound and the second fluorine-containing compound may be the same or different, and
- wherein an average crush strength of the catalyst is greater than 12 lb based on at least two samples of pellets of the catalyst measured in accordance with ASTM D4179.
