Mathematical Modeling of Waste Fat Pre-Treatment for Biodiesel Production
Waste fat produced by tanneries during the processes in which raw hide is transformed into leather represents a very important raw material for biodiesel production. However, the acid number of this feedstock usually exceeds 2 mg KOH/g, which makes it unsuitable for direct processing into biodiesel via alkali-catalyzed transesterification. An effective and economically viable pre-treatment meth...
متن کاملHigh temperature solid-catalized transesterification for biodiesel production
Biodiesel has become more attractive recently because of its environmental benefits and the fact that it is made from renewable resources. Biodiesel is a mixture of monoalkyl esters of long chain fatty acids derived from renewable feed stock like vegetable oils and animal fats, mainly made of fatty acid glycerides. It is produced by transesterification processes in which oil or fat are reacted ...
متن کاملEconomic Analysis of Biodiesel and Glycerol Carbonate Production Plant by Glycerolysis
Techno-economic analysis of an indirect use of carbon dioxide within the route of glycerolysis of glycerol with urea is investigated. The results show that the net present value of the biodiesel-glycerol carbonate production by glycerolysis is higher than the biodiesel-glycerol carbonate production by direct carboxylationat at the end of the 12-year operation with similar capacities. The stocha...
متن کاملDevelopment 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...
متن کاملLow algal diversity systems are a promising method for biodiesel production in wastewater fed open reactors
Planktivorous fish which limit zooplankton grazing have been predicted to increase algal biodiesel production in wastewater fed open reactors. In addition, tanks with higher algal diversity have been predicted to be more stable, more productive, and to more fully remove nutrients from wastewater. To test these predictions, we conducted a 14-week experiment in Houston, TX using twelve 2,270-L op...
