Abstract

Biodiesel producted by transesterifiation reaction which on energy source. Biodiesel was developed in Indonesia as an anticipatis of energy crisis problem suppported by goverment national energy policy. This research is aimed to make biodiesel from cotton seed oil, studying the effect of agitation speed to the amount of biodiesel produced and determined the best catalyst activated by acid or base, and determined the characteristics of biodiesel produced. The transesterification process was occured at a temperature of 60oC, on weight of oil 100 grams, reaction time 1,5 hours, mole ratio of oil to methanol 1 : 9, catalyst concentration 0,5% -weight of oil for varions of agitation rate 400, 500 and 600 rpm, and variations of catalyst acid 0,47, 0,62 and 0,78% and alkaline activated with a concentration of 0,33, 0,44 and 0,66%. From the result was obtained the highest biodiesel yield of 95,45% for alkaline activated 0,66% for agitation speed of 400 rpm. Characterization of physical properties of biodiesel obtained here density of 878 kg/m3, 3,03 mm2/s kinematic viscosity, acid number 0.34 mg KOH/g sample, and the flash point 195oC.Keywords: biodiesel, clay catalysts, activation of acids and bases, transesterification

Abstract

Research on production biodiesel from kapok seed oil (ceiba pentandra) using an activated clay catalyst has been performed. It aimed to determine the effect of an activated clay catalyst on producing biodiesel, its quality and to study the effect of reaction time. Clay catalyst was activated by H2SO4 0.47%, 0.62%, 0.78% and NaOH with a concentration of 0.33%, 0.44%, 0.66%. Esterification with methanol in the ratio 1:12 with the addition of H2SO4 as much as 1% of the weight of oil. The next transesterification reaction, the kapok seed oil is reacted with methanol in the ratio of 1: 9 with the acids and bases activated clay catalyst. The reaction temperature of 60 °C, various of reaction time 1 hour, 1.5 hours and 2 hours. The results showed that the use of an activated clay catalyst H2SO4 0.78%, the reaction time of 1.5 hours to produce the highest yield 92.18%. Physical characteristics of biodiesel were obtained density 869 kg/m3, kinematic viscosity of 2.67 cSt, the acid number of 0.45 mg KOH/g sample and the flash point of 209oC. From the results was obtained biodiesel produced in compliance with the SNI 7182: 2015.Keywords: activation, biodiesel, clay, kapok seed oil, transesterification

Abstract

Heterogeneous solid base catalyst by modificated Eggshells through calcination, hydration, dehydration methods with iron powder through impregnation method to load calcium oxide with eggshells as precursor. The catalyst with the highest activity is obtained when the calcination temperature of 900°C and the calcination time of 3 hours under transesterification reaction conditions of a molar ratio of methanol/oil 6:1, catalyst dosage of 6% by weight, temperature of 70 °C for 2 hours with yield biodiesel results reached 86.20%.Keyword: biodiesel, calcination, calcium oxide, catalysts, iron powder.
