Review of biodiesel composition, properties, and specifications
TL;DR: In this paper, the fatty acid (FA) profiles of 12 common biodiesel feedstocks were summarized, and it was shown that several fuel properties, including viscosity, specific gravity, cetane number, iodine value, and low temperature performance metrics are highly correlated with the average unsaturation of the FA profiles.

Biodiesel production from waste cooking oils
Anh N. Phan,Tan M. Phan +1 more
TL;DR: In this article, the effects of methanol/waste cooking oils ratio, potassium hydroxide concentration and temperature on the biodiesel conversion were investigated, and the results showed that the resulting biodiesel experienced a higher but much narrower boiling range than conventional diesel.
Journal ArticleDOI
Biodiesel production, properties, and feedstocks
TL;DR: This review covers the process by which biodiesel is prepared, the types of catalysts that may be used for the production of biodiesel, the influence of free fatty acids on biodiesel production, the use of different monohydric alcohols in the preparation of biod diesel, the effects of blending biodiesel with other fuels on fuel properties, alternative uses for biod Diesel, and value-added uses of glycerol.
Journal ArticleDOI
A review on biodiesel production, combustion, emissions and performance
TL;DR: A literature review on biodiesel production, combustion, performance and emissions is presented in this article, where a vast majority of the scientists reported that short-term engine tests using vegetable oils as fuels were very promising but the longterm test results showed higher carbon built up and lubricating oil contamination resulting in engine failure.
Journal ArticleDOI
A review on novel processes of biodiesel production from waste cooking oil
TL;DR: In this paper, the effect of novel processes such as membrane reactor, reactive distillation column, reactive absorption, ultrasonic and microwave irradiation significantly influenced the final conversion, yield and in particular, the quality of product.

Technical aspects of biodiesel production by transesterification—a review
TL;DR: In this paper, various methods of preparation of biodiesel with different combination of oil and catalysts have been described and technical tools and processes for monitoring the transesterification reactions like TLC, GC, HPLC, GPC, 1H NMR and NIR have also been summarized.
Journal ArticleDOI
Biodiesel processing and production
TL;DR: Biodiesel is an alternative diesel fuel that is produced from vegetable oils and animal fats, which consists of the monoalkyl esters formed by a catalyzed reaction of the triglycerides in the oil or fat with a simple monohydric alcohol.

Variables affecting the yields of fatty esters from transesterified vegetable oils
TL;DR: In this paper, the authors showed that the conversion to methyl, ethyl and butyl esters from cottonseed, peanut, soybean and sunflower oils can be done in 1 hr with an alkaline catalyst.

TL;DR: The main advantages of using biodiesel are its renewability, better-quality exhaust gas emissions, its biodegradability and given that all the organic carbon present is photosynthetic in origin, it does not contribute to a rise in the level of carbon dioxide in the atmosphere and consequently to the greenhouse effect as mentioned in this paper.
