Anaerobic treatment of crude glycerol from biodiesel production.
In this study, we evaluated the use of an up-flow anaerobic sludge blanket (UASB) reactor to treat crude glycerol obtained from cottonseed biodiesel production. The laboratory-scale UASB reactor (7.0 L) was operated at ambient temperature of 26.5°C with chemical oxygen demand (COD) concentrations between 0.5 and 8.0 g/L. The volatile fatty acid contents, pH, inorganic salt contents and biogas p...
متن کاملCharacterization of Crude Glycerol from Biodiesel Production from Multiple Feedstocks
Glycerol is the principal by-product of biodiesel production. For each gallon of biodiesel produced, approximately 0.3 kg of crude glycerol accompanies. Such crude glycerol possesses very low value because of the impurities contained. As the demand and production of biodiesel grow exponentially, the utilization of the glycerol becomes an urgent topic. The make-up of crude glycerol varies depend...
متن کاملMixotrophic Production of Omega-3 Fatty Acid-rich Alga Phaeodactylum tricornutum on Biodiesel-derived Crude Glycerol
Crude glycerol is the major byproduct of the biodiesel industry. There is an abundance of this byproduct and purifying it for use in industries such as food, pharmaceutical, or cosmetic is prohibitively expensive. Developing an alternative use for crude glycerol is needed. Utilizing it as a carbon source in the fermentation of algae is one potential method for using this underutilized byproduct...
متن کاملValue-added uses for crude glycerol--a byproduct of biodiesel production
Biodiesel is a promising alternative, and renewable, fuel. As its production increases, so does production of the principle co-product, crude glycerol. The effective utilization of crude glycerol will contribute to the viability of biodiesel. In this review, composition and quality factors of crude glycerol are discussed. The value-added utilization opportunities of crude glycerol are reviewed....
متن کاملL (+)-lactic acid production by pellet-form Rhizopus oryzae NRRL 395 on biodiesel crude glycerol
BACKGROUND Given its availability and low price, glycerol derived from biodiesel industry has become an ideal feedstock for the production of fuels and chemicals. A solution to reduce the negative environmental problems and the cost of biodiesel is to use crude glycerol as carbon source for microbial growth media in order to produce valuable organic chemicals. In the present paper, crude glycer...
