This module will acquaint you with the fuel specification that defines and sets the quality standards for biodiesel . The standard is framed as a set of property specifications measured by specific ASTM test methods. The standard for biodiesel is ASTM 6751-02. ASTM D 6751

Biodiesel production from Jatropha curcas: A review
free download

Biodiesel has attracted considerable attention during the past decade as a renewable, biodegradable and non-toxic fuel alternative to fossil fuels. Biodiesel can be obtained from vegetable oils (both edible and non-edible) and from animal fat. Jatropha curcas Linnaeus

Evaluation of glycerine from biodiesel production as a feed ingredient for broilers
free download

Glycerine from biodiesel production was used as a pure energy source in broiler diets formulated to meet typical commercial standards. In the first experiment, glycerine was added at 0, 5, and 10% of the diet while in the second experiment glycerine was added at 0

Valorization of coffee grounds for biodiesel production
free download

This work evaluates the use of spent coffee grounds (SCG) for biodiesel production . The SCG were characterized for their moisture content (12.1 wt%), total carbon (TC) and total nitrogen (TN)(52.2 and 2.1 wt% respectively), cellulose and total lignin contents (33.6 wt

Value-added utilization of crude glycerol from biodiesel production : a survey of current research activities
free download

Glycerol is a by-product from biodiesel industry. As the biodiesel production is increasing exponentially, the crude glycerol generated from the transesterification of vegetables oils has also been generated in a large quantity. Despite of the wide applications of pure

Biodiesel production from waste cooking oil using sulfuric acid and microwave irradiation processes
free download

ABSTRACT A comparative study of biodiesel production from waste cooking oil using sulfuric acid (Two-step) and microwaveassisted transesterification (One-step) was carried out. A two-step transesterification process was used to produce biodiesel (alkyl ester) from

Energy and greenhouse gas implications of biodiesel production from Jatropha curcas L
free download

Biodiesel production from Jatropha is one of the options being considered for partially substituting diesel fuel for transportation in Thailand. However, several issues such as food versus energy, energy and environmental benefits need to be addressed. Biodiesel from

In Situ Biodiesel Production from Fast-Growing and High Oil Content Chlorella pyrenoidosain Rice Straw Hydrolysate
free download

Rice straw hydrolysate was used as lignocellulose-based carbon source for Chlorella pyrenoidosa cultivation and the feasibility of in situ biodiesel production was investigated. 13.7 g/L sugar was obtained by enzymatic hydrolyzation of rice straw. Chlorella pyrenoidosa

Biodiesel production from waste sunflower cooking oil as an environmental recycling process and renewable energy
free download

Comparison of the optimum conditions of alkaline-catalyzed transesterification process for biodiesel production from pure sunflower cooking oil (PSCO) and waste sunflower cooking oil (WSCO) through transesterification process using alkaline catalysts was studied. To

Continuous production of lipase-catalyzed biodiesel in a packed-bed reactor: optimization and enzyme reuse study
free download

An optimal continuous production of biodiesel by methanolysis of soybean oil in a packed- bed reactor was developed using immobilized lipase (Novozym 435) as a catalyst in a tert- butanol solvent system. Response surface methodology (RSM) and Box-Behnken design

Getting lipids for biodiesel production from oleaginous fungi
free download

Biomass-based biofuel production represents a pivotal approach to face high energy prices and potential depletion of crude oils reservoirs, to reduce greenhouse gas emissions, and to enhance a sustainable economy (Zinoviev et al., 2010). Microbial lipids can represent a

Utilization of leather industry prefleshings in biodiesel production
free download

Fleshing wastes from tanneries create major environmental problems. Despite their considerable fat content, these wastes do not find important usage. Their disposal is also troublesome and costly. We have investigated the possible use of this fat in the production of

Key issues to consider in microalgae based biodiesel production
free download

All nations have been confronted with the energy crisis due to depletion of finite fossil fuels reserves, which results an increasing global demand of biofuels for energy security, economic stability and reduction in climate change effects, and generate the opportunity to

Biodiesel production from Spirulina-Platensis microalgae by in-situ transesterification process
free download

This research investigates the effect of reaction variables that strongly affect the cost of biodiesel production from non-edible Spirulina-Platensis microalgae lipids, and use the acid- catalyzed in situ transesterification process. Experiments were designed to determine how

Biodiesel production from algae
free download

Algae appear to be an emerging source of biomass for biodiesel that has the potential to completely displace fossil fuel. Two thirds of earths surface is covered with water, thus algae would truly be renewable option of great potential for global energy needs. This study

Recent strategy of biodiesel production from waste cooking oil and process influencing parameters: a review
free download

Cost of biodiesel produced from virgin vegetable oil through transesterification is higher than that of fossil fuel, because of high raw material cost. To minimize the biofuel cost, in recent days waste cooking oil was used as feedstock. Catalysts used in this process are usually

Production of biodiesel from waste cooking oil and factors affecting its formation: A review
free download

Growing concern regarding energy resources and the environment has increased interest in the study of alternative sources of energy. To meet increasing energy requirements, there has been growing interest in alternative fuels like biodiesel to provide a suitable diesel oil
