Abstract
A hydrogenolysis bimetallic supported catalyst comprising a first metal, a second metal, and a zeolitic support; wherein the first metal and the second metal are different; and wherein the first metal and the second metal can each independently be selected from the group consisting of iridium (Ir), platinum (Pt), rhodium (Rh), ruthenium (Ru), palladium (Pd), molybdenum (Mo), tungsten (W), nickel (Ni), and cobalt (Co).
Claims20
A hydrogenolysis bimetallic supported catalyst comprising a first metal, a second metal, and a zeolitic support;
- wherein the first metal and the second metal are different;
- wherein the first metal and the second metal are present in a total amount of from about 4 wt. % to about 0.8 wt. %, based on the total weight of the hydrogenolysis bimetallic supported catalyst;
- wherein the first metal comprises platinum (Pt), wherein Pt is present in a total amount of from about 0.2 wt. % to about 0.4 wt. %, based on the total weight of the hydrogenolysis bimetallic supported catalyst, wherein the second metal comprises Ir, wherein Ir is present in a total amount of from about 0.2 wt. % to about 0.4 wt. % based on the total weight of the hydrogenolysis bimetallic supported catalyst;
- wherein Pt and Ir are present in a weight ratio of Pt to Ir of from about 0.8:1 to about 1.2:1;
- wherein the zeolite support comprises ZSM-5;
- and wherein the zeolitic support is characterized by a weight ratio of silica to alumina (SiO2/Al2O3) of from about 250 to about 300.
