A method for producing a bio-jet fuel includes a reaction step of hydrogenating, isomerizing, and decomposing a crude oil obtained by a deoxygenation treatment of a raw oil containing a triglyceride and/or a free fatty acid, by using a hydrogenation catalyst and an isomerization catalyst in a hydrogen atmosphere under conditions of a reaction temperature of 180&#xb0; C. to 350&#xb0; C. and a pressure of 0.1 MPa to 30 MPa.

To provide a method for catalytically cracking waste plastics wherein the efficiency in decomposition is high; even polyethylene composed of linear chain molecules difficult in decomposition is decomposable at a low temperature and decomposed residue is hardly produced; the process is simple since dechlorination can be achieved at the same time with catalytically cracking waste plastics in one reaction vessel; and oil fractions can be recovered at 50% or more on a net yield basis. The method for catalytically cracking waste plastics of the present invention has a constitution in which waste plastics are loaded as a raw material into a granular FCC catalyst heated to a temperature range from 350&#xb0; C. to 500&#xb0; C. inside a reaction vessel, thereby decomposing and gasifying the waste plastics in contact with the FCC catalyst.

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.

Catalyst and process for producing liquefied petroleum gas

A synthesis gas is produced from a carbon-containing starting material such as a coal; a CO-containing gas is separated from the resultant synthesis gas, whereby obtaining a gas containing carbon monoxide and hydrogen; a methanol- and/or dimethyl ether-containing gas is produced from the resultant gas containing carbon monoxide and hydrogen; meanwhile, a H-containing gas is produced from the CO-containing gas and the HO-containing gas separated from the lower-paraffin-containing gas by a shift reaction; a lower-paraffin-containing gas containing propane or butane as a main component of hydrocarbons contained therein is produced from the methanol- and/or dimethyl ether-containing gas and the H-containing gas; and a HO-containing gas is separated from the resultant lower-paraffin-containing gas, whereby obtaining a liquefied petroleum gas.

Process for producing liquefied petroleum gas

At least one selected from the group consisting of methanol and dimethyl ether, and hydrogen are reacted in the presence of a catalyst for producing a liquefied petroleum gas in which an olefin-hydrogenation catalyst component is supported on a zeolite, to produce a hydrocarbon containing propane or butane as a main component, i.e., a liquefied petroleum gas.
