Title
(PT) "processo para preparação de biodiesel a partir de gordura renovável com lipase comocatalisador e desidratação em linha"
Abstract
(PT)
processo para preparação de biodiesel a partir de óleo e gordura renováveis catalisado por lípase com desidratação em linha. é mostrado um processo para preparação de biodiesel a partir de óleo e gordura renováveis catalisado por lípese com desidratação em linha. o processo usa um ácool de cadeia curta roh como um receptoracila, e utiliza uma lípase como o catalisador para catalisar transesterificação de estoque de alimentação de óleo e gordura com o dito álcool de cadeia curta, de modo a sintetizar biodiesel; e desidratação em linha com uma membrana ou peneira molecular é realizada durante todo o processo ou parte do processo de reação. tal processo de desidratação em linha simplifica grandemente o procedimento de operação, e prevê bons benefícios econõmicos e ambientais.
