| 1. A process for producing at least one fatty acid ester and glycerin with a high degree of purity, comprising reacting a
vegetable or animal oil with an aliphatic monoalcohol containing 1 to 18 carbon atoms in the presence of at least one catalyst
comprising:
mixtures of zirconium oxide and alumina having formula:
(ZrOx)y(Al2O3)1-y
where x has the value 1.5 to 2.2 and y has a value of 0.005 to 0.995;
or mixtures of antimony oxide and alumina having formula:
(SbOx)y(Al2O3)1-y
where x has the value 1.6 to 2.2 and y has a value of 0.005 to 0.995.
