Ultrasound Assisted In Situ Esterification of Rubber Seeds Oil for Biodiesel Production (RESEARCH NOTE)

Ultrasound-Assisted Biodiesel Production in microreactors

The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...

Production of Biodiesel from Sludge Palm Oil by Esterification Process

Sludge palm oil (SPO) is an attractive feedstock and a significant raw material for biodiesel production. The use of SPO can lower the cost of biodiesel production significantly. In this study biodiesel fuel was produced from SPO by esterification process using P-toluenesulfonic acid (PTSA) as acid catalyst in different dosages in presence of methanol to convert free fatty acid (FFA) to fatty a...

Development of Clay Foam Ceramic as a Support for Fungi Immobilization to Biodiesel Production (RESEARCH NOTE)

Biodiesel is an attractive alternative fuel because of its nontoxicity and biodegradability properties. Biodiesel is produced through transesterification of vegetable oils’ triglyceride. It is obtained from vegetable oils or fats either by chemical or enzyme-catalyzed transesterification with methanol or ethanol. By using whole-cell biocatalyst immobilized within biomass support particles (BSPs...

Ultrasound - assisted production of biodiesel FAME from rapeseed oil in a novel two - compartment reactor

Optimization of Biodiesel Production by Chemical Trans-esterification of Sunflower Oil

Vegetable oils and fats in comparison with diesel fuel have high viscosity, by transesterification method the viscosity of oil can be decreased. Transesterification of triglyceride with alcohol is one of the methods for production of biodiesel. In this study sunflower oil, methanol and ethanol, with molar ratio of (1:3, 1:4, 1:6, 1:8) and temperature (40, 50, 60 º C) were dependent parameters e...

تولید دیزل زیستی از دانه های گوجه فرنگی با فرآیند تبادل استری مستقیم

Abstract : In-situ process is one of the biodiesel production methods in which seeds are used directly in the reaction without oil extraction. The objective of this research is to optimize the biodiesel production conditions for the in-situ reaction using tomato seeds as a feed. The effects of reaction parameters such as molar ratio of oil to alcohol and catalyst to oil weight percent ratio on ...
