A catalyst with a mixed zinc and aluminum oxide base having a spinel structure surstoichiometric in zinc, in which part of the Zn atoms are in the octahedral position, a process for preparation of the same and use of the same in a process for preparation of a compound of linear monocarboxylic acid alcohol esters with 6-26 carbon atoms from a vegetable or animal oil, neutral or acid, virgin or recycled, with monoalcohols of 1-18 carbon atoms allowing an ester that can be used as a motor fuel or a heating fuel and a pure glycerine to be obtained directly in one or more steps.

Heterogeneous catalyst of the zinc aluminate spinel type surstoichiometric in zinc and use thereof in a process for preparation of alcohol esters from triglycerides and alcohols

A process for preparing a composition of alcoholic esters of straight chain monocarboxylic acids containing 6 to 26 carbon atoms and glycerin, starting from a vegetable or animal oil, neutral or acidic, virgin or recycled with mono-alcohols containing 1 to 18 atoms, in the presence of a zinc aluminate catalyst and in the presence of a controlled quantity of water, can directly produce, in one or more steps, an ester which can be used as a propellant or fuel along with glycerin having improved purity containing a reduced quantity of ethers by using a partially dried catalyst.
