The goal of this research was to test barium chloride (BaCl2) impregnated calcined razor clam shell as a solid catalyst for transesterification of rubber seed oil (RSO) in a packed bed reactor (PBR). The waste razor clam shells were crushed, ground, and calcined at 900 °C in a furnace for 2 h to derive calcium oxide (CaO) particles. Subsequently, the calcined shells were impregnated with BaCl2 by wet impregnation method and recalcined at 300 °C for 2 h. The synthesized catalyst was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectrometer (EDS),  Brunauer-Emmett-Teller (BET) surface area, and basic strength measurements. The effects of various parameters such as residence time, reaction temperature, methanol/oil molar ratio, and catalyst bed length on the yield of fatty acid methyl ester (FAME) were determined. The BaCl2/CaO catalyst exhibited much higher catalytic activity and stability than CaO catalyst influenced by the basicity of the doped catalyst. The maximum fatty acid methyl ester yield was 98.7 % under optimum conditions (residence time 2.0 h, reaction temperature 60 °C, methanol/oil molar ratio 12:1, and catalyst bed length 200 mm). After 6 consecutive reactions without any treatment, fatty acid methyl ester yield reduced to 83.1 %. The option of using waste razor clam shell for the production of transesterification catalysts could have economic benefits to the aquaculture and food industries. Copyright © 2018 BCREC Group.

Isolation of rubber seed (Hevea brasiliensis) oil have carried out by using soxhlet extraction with n-hexane as solvent. This research have been determined of fatty acid composition of rubber seed oil. Separation of free fatty acid from triglyceride done by ethanol 96 %. The oil phase was analysed by gas chromatography - mass spectrophotometer. It was resulted five chromatogram peaks of fatty acid methyl ester, there are methylester from palmitic acid (9.12%), linoleic acid (44.69 %), elaidic acid (44.69 %), stearic acid (8.89 %>) and 11,14-eicosadienoic acid (5.30 %) respectively.

In this study, different characteristics of sustainable renewable biodiesels (those have a high potential of their production worldwide and in India) were compared with the characteristics of neat diesel to determine optimistic biodiesel for the diesel engine at 250 bar spray pressure. Optimistic fuel gives a comparatively lower level of emissions and better performance than other selected fuels in the study. Rubber seed oil methyl ester was investigated as an optimistic fuel among the other selected fuels such as sunflower oil methyl ester, neem seed oil methyl ester, and neat diesel. To enhance the performance characteristics and to further decrease the level of emission characteristics of fuel ROME, further experiments were conducted at higher spray (injection) pressures of 500 bar, 625 bar, and 750 bar with varying ignition delay period via varying its spray timings such as 8°, 13°, 18°, 23°, 28°, and 33° before top dead center. Spray pressure 250 bar at 23° before top dead center was investigated as an optimistic operating condition where fuel rubber seed oil methyl ester gives negligible hydrocarbon emissions (0.019 g/kW h) while its nitrogen oxide (NOX) emissions were about 70% lesser than those observed with neat diesel, respectively.

The CaO heterogeneous catalysts can be prepared by CaCO3 calcination process, with one source of CaCO3 being a crab shell from seafood waste. The preparation of the heterogeneous catalyst was successfully carried out by modification with KOH using a wet impregnation method at 800oC for 5 hours. The purpose of this research is to determine the physical and chemical characteristics of heterogeneous catalyst of K2O-modified crab shell and to examine the heterogeneous catalyst of K2O-modified shells in converting rubber seed oil into biodiesel. The results showed that the lowest basic alkalinity possessed without modified catalyst (1.0428 mmol g-1) and the highest alkali possessed potassium-modified catalyst (1.8314 mmol g-1). Characterization of specific surface area of ??crab shells without and with modified K2O were relatively the same. The surface morphology of the catalyst without and K2O modified was uniform. The catalyst examination results for conversion of rubber seed oil (Hevea brasiliensis) to biodiesel, the optimum catalyst concentration of 3% and the molar ratio of oil:methanol of 1:9 capable converting to biodiesel with the yield of 91.05%. The content of biodiesel were stearic methyl ester, linoleic methyl ester, linolenic methyl ester, and palmitic methyl ester.

Thermal energy is used in the process of heating, cooling and product design purpose. In this work, two non-edible oils are considered and their thermal conductivity, specific heat and thermal degradation are experimentally determined as a function of temperature using, guarded hot plate method, differential scanning calorimetry (DSC) and thermogravtic analyser (TGA). Miniature difference between the obtained and actual thermal conductivity values are influenced by the fatty acid composition. In the present work Pongamia Honge Oil Methyl Ester (HOME) and Rubber Seed Oil Methyl Ester (ROME) are studied and their properties are determined experimentally for a temperature range of 25 to 80C. It has been observed that thermal conductivity of HOME decreases from 0.168 to 0.124 W/mK and for ROME thermal conductivity decreases from 0.143 to 0.113 W/mK. Thermal degradation and specific heat were studied using TGA and DSC. Specific heat was studied in the range from 35 to 120 C. For HOME, the specific heat varies from 2.345 to 2.64 kJ/kgK. For ROME, the specific heat varies from 1.572 to 1.992 kJ/kgK.
