In the third workshop of catalysis and sustainability (CATSUS 3). Book of Abstracts. Lisboa, Portugal: FCUNL, 2017, p. 23.http://hdl.handle.net/10400.21/7517Nowadays, around 90% of biodiesel is produced by the transesterification reaction of triglycerides with low molecular weight alcohols using acid/basic catalysts. Homogeneous catalytic transesterification is still major industrial biodiesel production process using alkali hydroxides and methoxides. However, they have disadvantages such as reusability, renderability and separability. Lately, researchers have been focusing on heterogeneously catalysed process.engWasteCatalystsconference object
