Abstract

Nyamplung (Calophyllum inophyllum L.) has a high survival potency in wide variety environment, fruitingall year round and easy regeneration. Nyamplung oil is the most suitable raw material as feedstock of biofuelbecause of its high yield of the seeds and in utilization not compete with food interests. Utilization nyamplungoil for Green Diesel through two basic stages, processing into Pure Plant Oil (PPO) and PPO upgradinginto Green Diesel. PPO upgrading with target Green Diesel further divided into two stages:Hydrodeoxygenation (HDO) and isomerization. In this preliminary study, PPO upgrading is only carried outby HDO only using NiMo catalyst. HDO is done in batch processes to identify the characteristics of theprocess at a temperature of 300oC, bar and the 5% catalyst. Meanwhile, to increase the nyamplung oilconversion into diesel, then the multi-stage Hydrogen (H2) was done in the process. Stage number of H2inserting is the major parameter in this HDO process. In the multi-stage H2: 1 times, 2 times and 4 times intothe reactor. Multi-stage H2 is done by replacing the H2 gas into the reactor, after a process gas frompreviously discarded. Carboxilation and carbonilation occurs in HDO process. By multi-stage H2, it showedan increasing yield of diesel conversion. From 1x stage H2 inserting to 2x and 4x stages of H2, it improve theyield from 0.32% to 0.76% and to 1.3%. This shows that the yield HDO is determined largely by theeffectiveness of H2 and PPO contact with the catalyst therein. Unfortunately, this condition is very difficult tobe achieved at a high pressure batch reactor. Further testing is doing HDO in a continuous reactor andobtained the conversion reached a yield of 50.48%.

Abstract

Production of biodiesel has been conducted through several processes such as esterification andtransesterification by homogeneous catalyst in which use either acidic or alkaline substances.Homogeneous catalysts have some negative impacts to the environment, because technically itrequires further treatment process such as washing. Therefore, the use of heterogeneouscatalysts is proposed to be best way to overcome this problem. The advantages of heterogeneouscatalysts are not only for its ease in recovery but also for its reusability. Moreover, it isenvironmentally friendly and cheap which only undergo a single process of transesterification.Calcium oxide is well-known as one of heterogeneous catalysts. It were activated by pretreatmentwith methanol and then it was continued by transesterification reaction. The optimal reactiono conditions were obtained at temperature 60 C, atmospheric pressure, and 4 h reaction time.Calcium oxides shows good activity in transesterification reaction using either palm or jatropha oil.The highest conversion of palm oil is approximately 62,51% within catalyst 3% by weight oil,whereas jatropha oil is approximately 53.10 % within catalyst 10% by weight oil. The regeneratedcatalyst shows low catalytic activity which is indicated by small presence of methyl ester in theproduct.Key words : biodiesel, heterogen catalyst, calcium oxide, palm oil, jatropha oil

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.
