Abstract

Indonesia has abundance of biomass that underutilized, including oil palm biomass in such as empty fruit bunches and palm fronds. The biomass can be converted into biohydrocarbons through a pyrolysis process that produces bio-oil and followed by an up-grading process to improve its quality. Upgrading Bio-oil into biohydrocarbons can be conducted through various production processes, including hydrothermal processes. Bio-oil has different chacateristic compared to diesel fuel. Bio-oil has a high water content (11-50%), high acidity, and high viscosity (> 40 cP). Based on these characteristics, the hydrothermal process has the advantage of being able to operate with raw materials that have a high water content. The operating conditions of the hydrothermal process are 300 – 400 oC, 150 – 200 bar. For this reason, a bio-oil upgrading reactor was designed using a hydrothermal process to operate at a temperature of 420 oC and a pressure of up to 220 bar.

Abstract

Biodiesel has become favorable fuel for diesel fuel substitute to overcome the limited fossil fuel resources while facing the increasing of energy consumption. However, the use of FAME biodiesel is currently limited to mixing up to 30%. Therefore, it is necessary to consider other fuels as an alternative to diesel oil. One of them is by developing second generation biodiesel, which produced from the upgrading process of bio-oil as a result of pyrolysis. Bio-oil can be upgraded to fuel with range naphtha through two main processes that consisted of hydro-processing and catalytic cracking. Techno-economic studies on bio-oil production from oil palm biomass have been studied but the techno-economic studies up to upgraded bio-oil have not included. Before a techno-economic study was carried out, it was necessary to select the process technology route of upgrading bio-oil. Therefore, it is required to conduct a study of industry and the comparison of second generation biodiesel production technology from the upgrading of oil palm-based bio-oil to obtain an optimum process flow diagram. Process simulations were conducted using ChemCad software so that the mass balance and ratio of energy consumption was obtained. This work estimated the biofuel produced from palm residues collected from 19 units of a 60 tons/hour palm oil mill. The bio-oil input is 70.35 tons/hours with upgrading oil yield of 32.21%. The energy yield of this model is 35.7% while required 76.5 MMJ/hour of the energy. The energy required for this process can be provided by an integrated fuel upgrading facilities that connected with the palm bio-oil production plant could provide self-sustainable production facilities.
