Grosmann, Mikkel T.; Andrade, Thalles A.; Bitonto, Luigi di; Pastore, Carlo; Corazza, Marcos L.; Tronci, Stefania; Errico, Massimiliano published the artcile< Hydrated metal salt pretreatment and alkali catalyzed reactive distillation: A two-step production of waste cooking oil biodiesel>, Related Products of 112-63-0, the main research area is potassium hydroxide biodiesel waste cooking oil kinetic reactive distillation.
In this work, a novel method was proposed for the conversion of waste cooking oil into biodiesel. A two-step approach based on a pretreatment with AlCl3•6H2O to convert FFA into the relevant Me esters, followed by the complete transesterification of glycerides, under KOH catalysis in a reactive distillation column, was considered. The pretreatment with AlCl3•6H2O allowed to obtain two different phases: an oily phase, rich in FAME and triacylglycerols and with a very limited content of water (100 ppm), and residual FFA (1 mgKOH /goil), and a methanol phase, in which most of the catalyst, water and monoacylglycerols were dissolved in. The esterified stream was characterized by its composition and used to obtain new kinetic parameters to be used in the setting of the reactive distillation The reactive distillation column was proved to be efficient in obtaining a biodiesel stream with a purity requirement conform to the EN14214 standards The transesterification step was characterized by a sp. heating requirement of 701.3 kJ per kg of biodiesel produced.
Chemical Engineering and Processing published new progress about Biodiesel fuel. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Related Products of 112-63-0.
