Abstract:
1. A method of forming a product by heterogeneous catalysis, the method comprising: contacting a feedstock comprising a triglyceride and a free fatty acid with an alcohol in the presence of a heterogeneous catalyst, the catalyst comprising a mixture of zinc oxide nanocrystals and lanthanum oxide, the zinc oxide nanocrystals having a mean grain size between about 20 and 80 nanometers with at least one of the nanocrystals including a mesopore having a diameter of about 5 to 15 nanometers; wherein both the catalyzed transesterification of the triglyceride and the catalyzed esterification of the free fatty acid occur to form the respective corresponding alcoholic esters of the triglyceride and the free fatty acid.
