Abstract
In an embodiment, a method of forming a catalyst can comprises: treating a detemplated pentasil zeolite material with a phosphorus-containing compound to form a phosphorus treated zeolite; combining a hydrogenating material, the phosphorus treated zeolite, and a binder material to form a mixture; forming the mixture into a shaped body, wherein the mixture is formed into the shaped body without the mixture being heat-treated; and calcining the shaped body to form the catalyst. Combining the hydrogenating material with the phosphorus treated zeolite and the binder material occurs prior to forming of the shaped body.
Claims16
A method of forming a catalyst for use in aromatic alkylation, comprising:
- treating a detemplated ZSM-5 zeolite material with a phosphorus-containing compound to form a phosphorus treated zeolite;
- combining a hydrogenating material, the phosphorus treated zeolite, and a binder material to form a mixture;
- forming the mixture into a shaped body, wherein the mixture is formed into the shaped body without the mixture being heat-treated;
- and
- calcining the shaped body to form the catalyst.
A catalyst formed by the method comprising:
- treating a detemplated ZSM-5 zeolite material with a phosphorus-containing compound to form a phosphorus treated zeolite;
- combining a hydrogenating material, the phosphorus treated zeolite, and a binder material to form a mixture;
- forming the mixture into a shaped body, wherein the mixture is formed into the shaped body without the mixture being heat-treated;
- and
- calcining the shaped body to form the catalyst.
A method of aromatic alkylation, comprising:
- contacting a stream containing an aromatic and a catalyst, wherein the catalyst is formed by the method comprising
- treating a detemplated ZSM-5 zeolite material with a phosphorus-containing compound to form a phosphorus treated zeolite;
- combining a hydrogenating material, the phosphorus treated zeolite, and a binder material to form a mixture;
- forming the mixture into a shaped body, wherein the mixture is formed into the shaped body without the mixture being heat-treated;
- and
- calcining the shaped body to form the catalyst;
- and wherein the aromatic comprises toluene and
- alkylating toluene to form para-xylene.
A method of forming a catalyst, comprising:
- combining a hydrogenating material, an active catalyst material comprising a ZSM-5 zeolite, and a binder material to form a mixture;
- forming the mixture into a shaped body, wherein the mixture is formed into the shaped body without the mixture being heat-treated;
- and
- calcining the shaped body to form the catalyst.
