SYNTHESIS OF METHYL AND ETHYL ESTERS (BIODIESEL) OR HIGH ALCOHOLS OF FATTY ACIDS VIA REACTION OF TRANSIATERIFICATION OF TRIACYLGLYCEROS, PROMOTED BY BIOHESE GEOSHEMATOSES PHASE

摘要

"synthesis of methyl or ethyl esters (biodiesel), or higher alcohol, fatty acids via triacylglycerol transesterification reaction in bio-oils or bio-fats, promoted by heterogeneous catalysts based on magnetic phosphate mining tailings." The present invention relates to the process for biodiesel production by transesterification of triacylglycerols using heterogeneous catalysts derived from magnetite rich magnetic waste (fe304), material hereinafter referred to as "magnetite" from the mining of apatite mineral deposits. Specifically, the present invention relates to a process for producing biodiesel by transesterification of triacylglycerols of bio-oils or bio-fats with methyl alcohol, ethyl alcohol, or any other similar formation of higher alcohol esters using the different heterogeneous catalyst. of those traditionally found in the state of the art. the catalyst claimed herein consists of magnetite material (fe304) from phosphate mining waste mixed with calcium oxide; The mixture is calcined at a temperature between 100 ° C and 1000 ° C.
