生物柴油是一种绿色可再生能源,目前主要采用固体碱催化酯交换反应进行制备。以金属氧化物为载体的固体碱是催化酯交换反应的一种环境友好型催化剂。本文综述了以金属氧化物为载体的固体碱研究状况,并对用于制备生物柴油的该类催化剂发展方向提出了建议。
Biodiesel is a green and renewable energy, and at present its most effective preparation method is to use the catalyzed ester transesterification of the solid alkali. The solid alkali with the metal oxide as the carrier, which is used to catalyze transesterification, is a kind of environment friendly catalyst. In this paper the research situations of the solid alkali with the metal oxide as the carrier are summarized. Some suggestions on the developing direction of the catalysts for the biodiesel are presented.
