The effect of operating parameters of hydrodynamic cavitation - assisted alkaline catalyzed transesterification of sunflower oil with methanol on the degree of triglyceride conversion
INTERNATIONAL JOURNAL OF CHEMICAL REACTOR ENGINEERING(2022)
Abstract
The effect of operating parameters such as reaction mixture inlet pressure p (1) (101.3-1013.2 kPa), methanol to oil molar ratio M (1) (3-12), the concentration of catalyst C ( c ) (0.0-1.0 wt%), temperature T (25-50 degrees C) and the number of passes of the reaction mixture through the venturi type hydrodynamic cavitation reactor n (1-12) on alkali-catalyzed transesterification of sunflower oil with methanol assisted by hydrodynamic cavitation (ACTC) on the value of the degree of triglyceride conversion (DTC) was investigated. ACTC was performed by the venturi-type hydrodynamic cavitation reactor (VCR) of our construction. It was found that the values of DTC increase with the increase in p (1), M (1), C ( c,) and n, and decrease with the increase in T. Cavitation yield (CY) values were calculated. The ACTC was proved to be the simplest, fastest, and most highly energy-efficient current technology for the production of biodiesel.
