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...
متن کاملBiodiesel production from soybean oil using ionic liquid as a catalyst in a microreactor
In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content (wt. %) were optimized using Box–Behnken experimental design. In order to predict the FAME conte...

متن کاملTransesterification of Nannochloropsis oculata microalga's oil to biodiesel using calcium methoxide catalyst
Biodiesel is an environmental friendly liquid fuel similar to conventional diesel in combustion properties. It has received international attention in recent times, as that biodiesel is renewable, non-toxic and safe to store. In this study, high grade biodiesel was produced from microalgae (Nannochloropsis oculata) derived lipids via transesterification reaction with methanol in the presence of...
متن کاملConjugate Addition of Indoles to α,β-Unsaturated Ketones Using a Brønsted Acid Ionic Liquid as an Efficient Catalyst
The Brønsted acid ionic liquid [PyN(CH2)4SO3H][p-CH3PhSO3] has been reported as an efficient catalyst for the Michael addition reaction of indoles to α,βunsaturated ketones. Satisfactory results were obtained, with excellent yields and a simple experimental procedure. The catalyst could be recycled and reused up to three times without any noticeable decrease in the catalytic activity.
