A process for the production of an ester product from a mixture of at least two different ester compounds includes the steps of mixing together at least two different starting ester compounds to form a first ester mixture; and contacting the first ester mixture with a catalyst including from 30-60% of calcium oxide and at least one second metal oxide at a temperature of at least 180° C., for a duration of at least one hour, with mixing, to form a second ester mixture having a melting point which is lower than the melting point of the first ester mixture.

The invention relates to a composition containing an oxide supported oxidative coupling of methane catalyst having an excellent balance of catalytic activity and selectivity while retaining desired levels mechanical stability suitable for commercial reactor application. Particularly, the inventive catalyst is an oxide supported catalyst with the oxide catalyst support having a spherical diameter of less than 2 mm and a surface area of less than less than 9.5 m.sup.2/g while retaining a water sorption volume of at least 0.2 cc/g. The invention further provides a method for preparing such a composition containing an oxide supported catalyst, using a combination of thermal treatment of the oxide catalyst support, active component impregnation and followed up by calcination. Additionally, the invention also describes a process for producing C.sub.2+ hydrocarbons, using such a catalyst composition.
