Abstract

Petroleum oil still serves as a primary source of energy and national fuel. Oil reserves in Indonesia are depleting so substitution of fuel that derived from petroleum have to be sought. Recent years, a lot of research has done, whose purpose to find a fuel that can be an alternative source one of that is biodiesel. Raw material for making biodiesel can be from animal fat or vegetable oil. One type of vegetable oil that can be used as a raw material source of energy is kapok wood. This research is aimed to make biodiesel from cotton oil, to study factors which influences production, such as acid-based activated catalyst, the regeneration catalyst, and to determine the physical and chemical properties of biodiesel. The transesterification process was done on a mole ratio of oil: methanol 1: 9, oil mass 50 grams, the weight of the catalyst 1%-wt, temperature of 60°C during 90 minutes, the activation of clay catalysts are in acids and bases, and then recycle and regeneration of catalyst. This study given the biodiesel result having the largest yield of alkaline activation of the catalyst as much as 93.1%. Characterization of physical properties of biodiesel have a density 871 kg/m3, kinematic viscosity 3.5 mm2/s, acid number 0.37 mg KOH/g sample, and the flash point 210oC respectively. The catalyst regeneration cannot restore 100% reactivity of catalyst.Keywords: biodiesel, clay, recycle, regeneration, transesterification

Abstract

Basicly peat water is belong to surface water which is found in the wet land, like Riau Province. The characteristic of peat water are high color intensites (yellow or brown red), high organic content and low pH values about 2-5. For use as water source for domestic purposes, it was a process to change peat water toward clean water. One of the process was adsorption way. In this research is required by kaolin based geopolymers as adsorbent.The variable that used in this research is the mass of the adsorbent (1; 1,5; 2; and 2,5 gram, and stirring (time between 30,60 and 90 seconds) then tested of organic content. The best result from this research is that the adsorbent mass of 1 gram and the stirring time of 30s while adsorbent can increase from 51,192 mg/l to 0,63 mg/l on organics content.

Abstract

Biodiesel is a product of transesterification reaction fat/oil and methanol with the aid of catalyst. Catalysts is commonly used in the production of biodiesel is strong base catalysts such as NaOH and KOH which is difficult to separate from the product of the reaction because it has the same phase as the reactant. Therefore, it is necessary to develop catalyst technology in order to get the production process becomes more economical, applicable and environmentally friendly, one of the catalyst is geopolymer. Geopolymers are synthesized by reacting sodium silicate, metakaolin, and bottom ash. Geopolymers is used in transesterification reaction. The process variables are weight of oil 50 grams, stirring rate 400 rpm, reaction time 120 minutes, and temperature of 65 oC, with catalyst 2% (w/w) and mole ratio of methanol:oil 1:12.

Abstract

Off-grade oil is a raw material for biodiesel that has ALB levels> 2% so that the production of biodiesel made by two stage reaction, the esterification and transesterification. In general, biodiesel is produced using homogeneous catalysts. Homogeneous catalysts can be replaced by a heterogeneous catalyst. CaO catalyst has a high alkalinity but has shortcomings in the process of separation of the reaction products. Waste iron powder can be used as a support and to provide a catalyst Ca2Fe2O5 metal forming properties. This study aims to create a catalyst that has a high alkalinity and metallic, and study the performance of the catalyst in the transesterification reaction of palm oil off-grade. Esterification process were reacted at 60°C with a mole ratio of oil: methanol of 1:12 and 1% H2SO4 catalyst -b. The esterification reaction can reduce levels of ALB from 12.47% to 0.36%. Transesterification is done by varying the mole ratio of oil: methanol in a row is 1: 6, 1: 8 and 1:10, the amount of catalyst modification 1% -b, -b 2%, 3% -b, a reaction temperature of 50°C, 60°C, 70°C, and the reaction time 2 hours. Processing data using Response Surface Area (RSM), the amount of attack using Central Composite Design (CCD). The resulting yield ranging from 23.19% to 52.34%. The highest yield obtained at 70°C with a mole ratio of oil: methanol of 1:10 and the amount of catalyst Ca2Fe2O5 1%-b. Biodiesel characteristics such as density, kinematic viscosity, acid number and flash point are in accordance with the standards of Indonesian biodiesel. The most significant process conditions to yield biodiesel is the ratio of the mole ratio of oil: methanol and the amount of catalyst.Keywords : Biodiesel, Catalyst, Off-grade Palm Oi, Transesterification, Wasted Iron
