Natural zeolite from Pacitan Indonesia, as catalyst support for transesterification of palm oil

Transesterification of Waste Cooking Oil for Biodiesel Production Using Modified Clinoptilolite Zeolite as a Heterogeneous Catalyst

Reduction of fossil fuels sources, increasing of pollution gases emission, and global warming effects increase the demand of renewable fuels. One of the main candidates of alternative fuels is biodiesel. Biodiesel limits greenhouse gas effects due to the closed CO2 cycle. Biodiesel has more biodegradability, lower combustion emissions such as CO, SOx, HC, PM and lower toxicity than petro diesel...

Study regarding the Transesterification of Palm Oil

In this paper the transesterification of palm oil with methanol in the presence of NaOH as a catalyst was conducted in an experimental biodiesel installation. The kinetics of base-catalyzed transesterification of palm oil based on parameters such as oil and alcohol ratio, catalyst concentration and temperature were investigated to optimize the biodiesel production rate. Although, transesterific...

Synthesis and Characterization of CaO-TiO2 for Transesterification of Vegetable Palm Oil

This study explores the potential of titanium oxide impregnated on calcium oxide (CaO-TiO2) as catalyst in transesterification of vegetable palm oil (VPO) to produce biodiesel. The biodiesel yield increased with catalyst calcination temperature and reaction time, and the usage of CaO-TiO2 led to higher biodiesel production when compared to reaction catalyzed by CaO. Biodiesel yield of 93.33% wa...

Kinetics of Palm Oil Transesterification in a Batch Reactor

Methyl esters were produced by transesterification of palm oil with methanol in the presence of a catalyst (KOH). The rate of transesterification in a batch reactor increased with temperature up to 60°C. (Higher temperatures did not reduce the time to reach maximal conversion. The conversion of triglycerides (-TG), diglycerides (-DG) and monoglycerides (-MG) appeared to be second order up to 30...
