<p>This invention belongs to the field of catalysts for the transesterification of triglycerides, for the production of fatty acid glycerin and esters. This invention describes preparatory methods using solid catalysts and the formulation of these catalysts for the production of fatty acid esters, glycerin, and specifically, biodiesel through the heterogeneous transesterification reaction of triglycerides present in vegetable oils and fats, like soy, cotton seed, canola, castor, peanut oils and animal fat. The solid catalysts of this invention are sufficiently magnetic to use in the production of biodiesel from vegetable oils and fats, not only because they work in a similar fashion as state of the art catalysts, but also because of the low cost of the raw materials used in its production. The invention even describes the composition obtained by using the catalysts, in which the purity of the products, such as biodiesel and glycerin is greater than 96.5%.</p> |
