Abstract
This work presents a model for hydrotreating of palm oil components to produce green diesel. The main reactions of triglycerides and fat acids in the presence of a NiMo/γAl2O3 catalyst are shown, especially cracking of triglycerides, hydrogenation, decarboxylation, decarbonylation and fat acid reduction. These reactions were modelled using Aspen Plus® 7.3 software, where an equilibrium reactor was used to predict the reaction behavior. The influence of reactor pressure, temperature and H2/oil molar ratio was analyzed. The results showed that the optimized conditions are obtained at average pressure from 30â¯bar to 60â¯bar, temperature between 300â¯Â°C and 400â¯Â°C, and H2/oil molar ratio of 20.1. In the separation system the operating conditions adopted were 40â¯bar, 200â¯Â°C in the first plate and 1.013â¯bar, 60â¯Â°C in the second plate, resulting in green diesel purity of 97%. High levels of n-C18 and n-C16 production were attained, compared with other methods.
