Abstract
A catalyst for producing a liquefied petroleum gas according to the present invention comprises a Pd- and/or Pt-based catalyst component and a USY-type zeolite. By using the catalyst, a hydrocarbon containing propane or butane as a main component, i.e. a liquefied petroleum gas, can be produced with high activity, high selectivity and high yield from at least one of methanol and dimethyl ether.
Claims10
A process for producing a liquefied petroleum gas, comprising a step of:
- reacting at least one reactant selected from the group consisting of methanol and dimethyl ether with hydrogen in the presence of a catalyst, whereby producing a liquefied petroleum gas containing propane or butane as a main component,
- wherein the catalyst comprises a Pd- and/or Pt-based catalyst component in which Pd and/or Pt is supported on a support and a USY-type zeolite.
