Abstract

Along with the development of the era, the need for fuel oil is increasing. The development of research and the use of diesel motors in industry will not stop just because of the depletion of fossil fuels. The search for alternative fuels as a substitute for diesel continues to be carried out in addition to dealing with the problems of the global energy and environmental crisis as well as helping to develop automotive technology as a work of human culture. Methyl ester is a biofuel that can be used to power diesel engines. The availability of fuel oil derived from petroleum is running low and the price is increasing so that alternative fuel sources are needed. One of the substitutes for conventional fuels from petroleum is vegetable oil. Methyl ester is produced using a transesterification reaction by changing the triglycerides which are reacted with one of the alcohol compounds, namely methanol to become methyl ester, and a production capacity of 250,000 tons / year is obtained. The main design tool is the CSTR (Continuous Flow Stirred-Tank Reactor) reactor which is used as a place for the transesterification reaction between triglycerides and methanol to produce methyl ester (main product) and glycerol (by-product). The operating temperature used is 333.15K. Based on the calculation results, the reactor volume is 57.28 m3, the reactor diameter (OD) is 168 in m with torispherical flanged and dished head and skirt support. Keywords: Methyl ester, reactor, transesterification, triglycerides.

Abstract

The decline in fossil fuel sources has prompted research into finding renewable fuels. One of environmentally friendly energy sources with high efficiency is by producing liquid oil from palm oil empty fruit bunch (EFB) and coal. Pre-treatment of empty fruit bunches using NaOH and various concentrations of H2O2, various ratios of EFB/coal, the ratio of CaO catalyst, chemical and physical characteristics were studied to produce the better liquid oil yield. The H2O2 concentrations are 0%, 1%, 2%, and 3%. The ratios of EFB/coal (R) are 0/100, 25/75, 50/50, and 75/25. The ratios of catalyst CaO/raw material are 0%, 3%, 6%, and 9%. It ran at 400 °C with 100 mL/min nitrogen gas flowing during one hour. The results showed that adding sodium hydroxide and hydrogen peroxide in the EFB pre-treatment increased the liquid oil yield. With an increase in the EFB/coal ratio, the liquid oil yield increased. Co-pyrolysis treated EFB and Coal with a ratio of 75:25 produced 32% liquid oil yield, but the liquid oil yield decreased to 19% with the addition of 9% CaO catalyst. However, the addition of CaO catalyst reduces the acidity and increases the calorific value of the liquid oil.
