Obtención de biodiésel a partir de aceites usados de cocina, utilizando un catalizador de ceniza de cacao ccn-51.

Abstract

The production of biofuels has gained increasing interest among industrial companies worldwide as a sustainable and environmentally friendly alternative to fossil fuels. Biodiesel, a renewable energy source, offers the opportunity to improve production economics and generate employment. To achieve high production efficiency, it is important to use a suitable heterogeneous catalyst that can reduce activation energy and accelerate the conversion process. Cocoa shell, a little-used waste from cocoa bean processing, can be utilized as a catalyst for biodiesel production from waste cooking oil. In this study, cocoa husks were crushed and sieved to obtain an average particle size of 0.8 mm, then incinerated at 700 °C for 4 hours until they turned into ash. The potassium carbonate crystals were extracted by washing 250 g of ash with 1 liter of distilled water and constant stirring for 1 hour. The filtering process was carried out, and the ash was evaporated to obtain potassium carbonate crystals, which were used as the catalyst.
