Abstract

Availability of fossil fuels are depleting resulted in higher mining costs and selling prices to the public. In addition, the results of its combustion also releases GHG to the environment. One way to reduce the use of fossil fuels is produce bio-oil through pyrolysis technology. Ketapang rod is a huge potential used as feedstock for bio-oil production because its high cellulose content (41.80%). Synthesis of bio-oil from Ketapang stem begins with the process of size reduction of biomass and natural zeolite to -100+200 mesh size. Then, into the natural zeolite impregnated Ni and Mo to form the bimetallic catalyst NiMo/NZA. The catalyst is then activated through the stages of calcination, oxidation, and reduction. Pyrolysis process is done by varying the weight percentage of catalyst to biomass, ie: 1.5%, 2%, 2.5%, and 3% w/w. In addition, the catalytic pyrolysis process is carried 3% NZA only  and 3% NiMo/NZA were activated by calcination process alone. The highest yield was obtained on the use of catalysts NiMo/NZA perfect activated which amounted to 91.05%. From physics analysis performed on the bio-oil obtained: density of 0.91 g/ml, viscosity 10.839 cSt, acid number 46.954 mg NaOH/g sample, flash point 52oC, and the heating value 42.66 MJ/Kg. The figures are included in the range of physical characteristics of diesel-oil. Five (5) the dominant compound results of chemical analysis by GC-MS of the bio-oil from Ketapang rod by using a catalyst NiMo/NZA 3% by weight are: 3,4,4-trimethyl-2-nonene (10.29%), isobutylene (8.84%), 2,2-dimethyl-butane (8.05%), 3,4,4-trimethyl-2-pentene (5.76%), and 2-methyl-1-heptene (5.26%).  Keywords: Bio-oil, Pyrolysis, and Catalyst NiMo/NZA

Abstract

Transesterification reaction is a reaction between the oil (triglyceride) with alcohol to produce methyl esters. One of commercial product is biodiesel. The production of biodieselfrom vegetable oils, especially seed oil saga is still very limited, it is necessary to develop a vegetable oil-based biodiesel. In this research, the manufacture of biodiesel bytransesterification reaction using natural zeolite catalysts are activated to H-Zeolite, with a variation of the molar ratio of reactants (1: 3, 1: 6 and 1: 9) and the number of H-zeolitecatalyst (6%, 8% and 10%) with a fixed variable is the reaction temperature 60 ° C, the reaction time of 200 minutes and the stirring speed of 200 rpm. From the test results showthat the molar ratio transesterification and the amount of catalyst affects the reaction rate toachieve equilibrium of the reaction. The best operating conditions obtained in this study isthe molar ratio of 1: 9 and the amount of catalyst 8% which resulted in a conversion reaction of 86.44%. Characteristics of biodiesel produced in this study meets the standards of commercial biodiesel with kinematic viscosity of 5.15 cp, specific gravity (40 ° C) 0.853 and saponification numbers were 0.49 mg KOH / g sample.Keywords : Biodiesel, H-zeolite, Oil, Transesterification.
