Biodiesel can be produced from various vegetable oils and animal fat. Abundant sources of vegetable oil in Indonesia, such as Calophyllum inophyllum, Ricinus communis, palm oil, and waste cooking oil, were used as raw materials. Multi-feedstock biodiesel was used to increase the flexibility operation of biodiesel production. This study was conducted to determine the effect of a combination of vegetable oils on biodiesel characteristics. Degumming and two steps of esterification were applied for high free fatty acid feedstock before trans-esterification in combination with other vegetable oils. Potassium hydroxide was used as a homogenous catalyst and methanol as another raw material. The acid value of C. inophyllum decreased from 54 mg KOH/gr oil to 2.15 mg KOH/gr oil after two steps of esterification. Biodiesel yield from multi-feedstock was 87.926% with a methanol-to-oil molar ratio of 6:1, temperature of 60 ℃, and catalyst of 1%wt. ©2020. CBIORE-IJRED. All rights reserved

Initial Stage

The production costs of biodiesel based on vegetable oil is not economical, so it is difficult for biodiesel to compete with petrodiesel. Waste cooking oil can be used as a source of raw materials for biodiesel production. This research aims to produce biodiesel from waste cooking oil. The initial stage is to pretreatment of waste cooking oil. At this step, the waste cooking oil is filtered to separate impurities from the raw material. After that, it is heated to 100 oC to remove the water content. The second stage is transesterification. At this stage, the reaction time remains for one hour at a temperature of 65 oC. the product is centrifuged to separate the catalyst. The highest yield was obtained in the 12: 1 molar ratio variable and the amount of catalyst 3%, which was 0.922. Yield obtained ranged from 0.853-0.922. An increase in the molar ratio is significant enough to increase the amount of yield. However, increasing the amount of catalyst especially from 2% to 3% is not significant enough to increase biodiesel yield. The characteristics of biodiesel produced are in accordance with SNI Biodiesel, density 870 Kg / cm3, viscosity 4.25 cSt, flash point 170, and acid number 0.4 mg-KOH/g biodiesel.

Biodiesel, as an alternative auto fuel for conventional fossil fuel, has drawn wide attention in recent years. In this research, a two-step process for biodiesel production using waste cooking oil as feedstock was studied in a pilot plant with a treatment capacity of 3 ton/d. The results show that: the process exihibited a good conversion ratio and the biodiesel displayed suitable physical-chemical properties in comparison with diesel fuel, such as flash point of 137°C, viscosity of 4.49 mm2/s, acid value of 0.44 mg KOH/g etc. The quality of biodiesel meets the agreement with the European specification defined by EN 14214. Afterwards, the mixture of biodiesel and diesel were test in the engine with a ratio of 50/50（v/v）, 20/80（v/v）, and 0/100（v/v）. It indicates the mixed fuel has a reasonable fuel consumption rates without diesel engine modification, when the biodiesel blended with 0# diesel as fuel. The present results demonstrated that the industrial scale plant would achieve promising objective with waste cooking oils and animal fats as raw material. Also, this biodiesel-based diesel fuel could be applied in Tianjin local public transportation system that improves its sustainable development.

Productive Potential

Macauba is an oleaginous palm tree widely found in Brazil. Its productive potential can reach 6000 kg of oil per hectare. In this study, crude vegetable oil was mechanically extracted from the mesocarp (pulp) of fresh Macauba fruit and subjected to physical-chemical determinations to analyse the following parameters: acid value, moisture content and kinematic viscosity. The results strongly indicate that Macauba palm oil is an alternative source of raw material for biodiesel production. Furthermore, concerning fatty acid composition, a predominance of unsaturated compounds was noted (75.92%) of which 63.21% are oleic acid, and 9.21% are linoleic acid. In this context, to produce ethyl esters, Macauba palm oil was subjected to alkaline transesterification by homogeneous catalysis, with microwave irradiation being applied to the heating step. The results indicated a conversion rate of 96.6%, for a molar ratio ethanol/oil of 12:1, a catalyst concentration equal to 1.0 wt% (KOH) and a reaction time equal to 60 seconds.

Cooking Oil

Biodiesel production is the reaction of raw oils with mixing and heating within catalyst and methanol. The raw oils usually come from vegetable oils and animal fats. Vegetable oils are a promising feedstock for biodiesel production since they are renewable in nature. Nevertheless, the physical properties of biodiesel pose some acute problems when used in an unmodified engine. It is important to diesel and biodiesels because it impacts components such as the fuel pump. Therefore, this paper intends to investigate the properties of biodiesel samples in terms of viscosity, density, flash point and acid values at different bio lipids and different mixing time. The evaluation is carried out on the three types of biodiesels: crude oil, crude palm oil, corn oil, and waste cooking oil. Methanol was chosen over the others for the transesterification process because it was cheaper. The esterification process, which reduces the amount of free fatty acids in the crude oil, will be performed with the help of an acid catalyst. Alkaline catalysts, in contrast, are used for the transesterification process. The comparison of all the samples shows that CPO is the better biodiesel than the other due to the physical properties of kinematic viscosity, density and flashpoint.

Global Agenda

The continued using of petroleum energy as a sourced for fuel is widely recognized as unsustainable because of the decreasing of supplies while increasing of the demand. Therefore, it becomes a global agenda to develop a renewable, sustainable and alternative fuel to meets with all the demand. Thus, biodiesel seems to be one of the best choices. In Malaysia, the biodiesel used is from edible vegetable oil sources; palm oil. The uses of palm oil as biodiesel production source have been concern because of the competition with food materials. In this study, various types of biodiesel feedstock are being studied and compared with diesel. The purpose of this comparison is to obtain the optimum engine performance of these different types of biodiesel (edible, non-edible, waste cooking oil) on which are more suitable to be used as alternative fuel. The optimum engine performance effect can be obtains by considering the Brake Power (BP), Specific Fuel Consumption (SFC), Exhaust Gas Temperature (EGT) and Brake Thermal Efficiency (BTE).

Due to the high cost of feedstock and catalyst in biodiesel production, the viability of the biodiesel industry has been dependent on government subsidies or tax incentives. In order to reduce the cost of production, food wastes including eggshells and oyster shells have been used to prepare calcium oxide (CaO) catalysts for the transesterification reaction of biodiesel synthesis. The shells were calcined at 1000 °C for 4 hours to obtain CaO powders which were investigated as catalysts for the transesterification of waste cooking oil. The catalysts were characterized by Fourier Transform infrared (FTIR) spectroscopy, thermogravimetric analysis (TGA), X-ray powder diffraction (XRD), and X-ray fluorescence (XRF) spectroscopy. Reaction parameters such as methanol-to-oil molar ratio, CaO catalyst concentration, and reaction time were evaluated and optimized for the percentage conversion of cooking oil to biodiesel esters. The oyster-based CaO showed better catalytic activity when compared to the eggshell-based CaO under the same set of reaction conditions.

This work has investigated the reusability of silica-titania in various temperatures (50 – 70°C) of biodiesel production from waste cooking oil. The reused silica-titania catalyst collected from silica-titania catalyst waste produced from the process of separating the catalyst from biodiesel products from palm oil and used cooking oil at various temperatures. The 1st and 2nd reused SiO2-TiO2 were characterized by DR UV-Vis and the spectra were deconvoluted for calculate the fraction of titanium in tetrahedral coordination. In addition the biodiesel products were characterized using FTIR, and several properties of biodiesel such as density, flow rate and acid value were analyzed in order to get the information about catalytic activity reused SiO2-TiO2. The results show the titanium tetrahedral fraction in reused catalyst (1st) and (2nd) are found to be 24,98% and 24.65%, respectively. The FTIR characterization of biodiesel products and waste cooking oil are almost similar. The analysis of waste cooking oil converted to biodiesel shows an optimum temperature of 50oC that at this temperature the lowest density or highest flow rate gave highest conversion of 47.82% using BCR1 and 39.13% using BCR2.
