ResumoDirect synthesis of liquefied petroleum gas (LPG) from a low-cost syngas derived from partial oxidation of methane with air (air-POM) was investigated over a hybrid catalyst consisting of methanol synthesis catalyst and Pd-modified Y-zeolite. The hybrid catalyst demonstrated a high activity and more than 73% selectivity for LPG fraction. BET, NH3-TPD and TPO-MS were carried out to study the properties of Pd–Y before and after reaction. The results indicated that coke deposition on Pd–Y was the main contribution to the slow deactivation of hybrid catalyst.
