Abstract

PROCESSO PARA TRANSESTERIFICAçãO DE óLEOS VEGETAIS E GORDURAS ANIMAIS, CATALISADO POR BASE FORTE MODIFICADA PARA PRODUçãO DE éSTERES ALQUìLICOS A presente invenção compreende a produção de ésteres alquílicos, tal como o Biodiesel, a partir de quaisquer óleos vegetais ou gordura animal, nas rotas metílicas ou etílicas, catalisada por base forte modificada, tanto na fase homogênea, onde se obtém um elevado rendimento, na reação de transesterificação, promovendo a decantação espontânea da glicerina. Após retirada do álcool em excesso do meio reacional, a neutralização do catalisador e sua purificação, obtém-se os ésteres (biodiesel) com pureza superior a 99%. Os catalisadores da presente invenção permitem tanto o processo em batelada, quanto contínuo, onde se pode utilizar toda a engenharia das plantas industriais que já operam com Metanol para operar na rota etílica. Os catalisadores na fase heterogênea, simplificam o processo, pois não contaminam os produtos, não necessitando as etapas de neutralização e purificação dos ésteres alquílicos, e não são consumidos durante o processo de transesterificação.PROCESS FOR TRANSESTERIFICATION OF VEGETABLE OILS AND ANIMAL FATS, MODIFIED BASED CATHYLIZED FOR PRODUCTION OF ALKYL ESTERS The present invention comprises the production of alkyl esters such as Biodiesel from any vegetable oils or animal fat in the methyl or ethyl routes. , catalyzed by a strong modified base, both in the homogeneous phase, where a high yield is obtained, in the transesterification reaction, promoting the spontaneous decantation of glycerin. After removal of excess alcohol from the reaction medium, catalyst neutralization and purification, the esters (biodiesel) of greater than 99% purity are obtained. The catalysts of the present invention allow both batch and continuous processes where all the engineering of industrial plants already operating with methanol can be used to operate on the ethyl route. The catalysts in the heterogeneous phase simplify the process as they do not contaminate the products, do not require the neutralization and purification steps of the alkyl esters, and are not consumed during the transesterification process.
