It is imperative to develop an efficient glycerol valorization processes in minimizing the net energy requirement and intensifying the biodiesel production. In this study, base-catalyzed transesterification of glycerol with dimethyl carbonate using microwave irradiation as heating method to produce glycerol carbonate was conducted by varying grades of glycerol, i.e. 70%, 86% and 99% purity, that is obtained from biodiesel plant. Metal oxide catalysts were used with varying operating parameters including reaction time, DMC/glycerol molar ratio, catalyst weight %, temperature and stirring speed. From the study on the effect of different operating parameters it was found that the type of catalyst used has the most significant effect on the transesterification reaction. Amidst the metal oxide catalysts examined, CaO gave the best performance. This study indicates the feasib...

Aqueous solution of ethanolamine (MEA), diethanolamine (DEA), 2–amino–2–methyl–1–propanol (AMP) and piperazine anhydrous (PZ) were chosen as the absorption liquids. A microporous hollow fiber membrane made of polyvinylidene fluoride (PVDF) was used as the medium for gasliquid absorption process. In this study, the operating temperature is fixed at 30°C, while the flowrate of CO2 and alkanolamine were in the range of 1000–5000 ml/min and 50–280 ml/min respectively. The feed gas was introduced directly to the shell of the module at 1–1.5 bar and the liquid flowed through the fiber lumen side. The CO2 transfer through the membrane was found to be reaction controlled and dependent on the type of amine used. The use of piperazine as an accelerator in the mixture of the absorption liquids gives a good impact on increasing the perfor...

The experimental densities data measured at various temperatures from 15°C to 90 °C at 1 °C interval were used to train the networks. The present work, applied a three layer back propagation neural network with nine neurons in the hidden layer. The results from the network are in good agreement with the measured data and the average absolute percent deviation was 0.29, 0.35, 0.72, 0.54, 0.68 and 0.72 % for the palm oil methyl esters and the ethyl esters of palm, canola, com and ricebran oil,respectively. The results of ANNs have also been compared with the results of theoretical estimations.

Biodiesel is one of the promising sustainable energy sources that can be a serious contender for fossil fuel if the raw materials can be obtained at an economically viable level. Efforts are underway to identify such raw materials and source from waste is definitely one of the main candidates. Some waste such as waste frying oil, bleaching earth and coffee ground are examples of waste that can be used to produce biodiesel at varying technical difficulties directly. However any other waste containing C, H, Nand P sources can be also potentially used for producing biodiesel indirectly, after transformation process involving microbes. For example,algae that grows on a C,H, Nand P sources from domestic and industrial wastewater (food,rubber, palm oil industries) and CO2 (from combustion of fuel) can be a source of raw material for biodiesel production. In this work, various challenges and opportunities available for producing biodiesel from waste sources, directly and indirectly are conceptually discussed.
