Influence of esterification of waste fats process parameters on agricultural biofuel production facilities

The paper presents the influence of esterification process parameters in waste fats on their level of reaction. Raw materials contained: frying rapeseed oil, animal lard, methyl alcohol and potassium hydroxide as a catalyst, necessary for reaction in non-pressure conditions. Esterification was carried out at 35-40 °C and 60-65 °C in two separate esterificators differing from one another with mixing systems. It has been established that in terms of contents of non-reactants allowed the obtained product meets the European EN 14214 standard, determining the quality of biodiesel.
