Abstract
A recyclable esterification or transesterification catalyst and methods for making and using the same are provided herein. The catalyst can be used to prepare biodiesel or methyl soyate from various feedstocks, including vegetable oils and animal fats. The catalyst can both esterify free fatty acids and transesterify mono-, di-, and triglycerides. The catalyst can also be combined with a metal oxide, and optionally calcined, prior to carrying out a catalytic reaction.
