Perfect products for fuel consumption
In present time fuel customers get offered a row of perfect products for fuel consumption enhancement, processes of combustion, both in petrol engines for cars, and to the diesel. All additives to petroleum are harmless to the car and serve as protection against the low-quality fuel which has got to a tank and will increase saving. They will secure and will burn any petroleum and if fuel is a ...

Development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils
The development and measured performance of a batch reactor for biodiesel production from fresh and waste vegetable oils as feedstock is presented. A biodiesel batch reactor was fabricated using locally sourced materials. Three different transesterification reactions were performed on the feedstocks using the fabricated reactor. The reaction temperature and time were varied for the fresh and ...

Energy analysis and potentials of biodiesel production from Jatropha Curcas in Tunisia
Oleaginous plants such as Jatropha Curcas Linnaeus (JCL), not intended for human consumption but used for biodiesel production, could contribute to beneficial outcomes. This plant grows on poor land (arid and marginal land) and is drought resistant. Jatropha Curcas is native to South America and widely grown in South and Central America, Africa, and Asia (Achten et al., 2007; Kumar et al., 2011). ...

Microtox aquatic toxicity of petrodiesel and biodiesel blends: The role of biodiesel's autoxidation products
The authors investigated the acute Microtox toxicity of the water accommodated fraction (WAF) of six commercial soybean biodiesel/petrodiesel blends at different oil loads. We analyzed five fatty acid methyl esters (FAMEs), C10–C24 n‐alkanes, four aromatics, methanol, and total organic carbon (TOC) content. At high oil loads, the WAFs' toxicity was significantly higher for blends containing ...

Sustainability assessment of microalgal biodiesel production processes: an exergetic analysis approach with Aspen Plus
Biodiesel production growth rate keeps increasing every year with the hope of replacing fossil based liquid fuel which is near exhaustion. Energy efficiency methods coupled with environmental and economic sustainabilities would render biodiesel production attractive. Algal cultivation and oil extraction processes are found to be energy intensive hence exergy destructive. This study presents the ...

The Effect of Feedstocks on InfraRed Blend Measurements
IR can be a simple, effective way to measure biodiesel blend ratios from a variety of feedstocks BY SANDRA RINTOUL With biodiesel hitting a new production record of 823 million gallons through October and expected to reach 1.28 billion by 2013, more biodiesel will ultimately be blended into our diesel fuel. This boom in production has opened the doors to a number of potential biodiesel ...

A New way to Skim and Save – Reprinted from Biodiesel magazine - Case study
Oil and water don’t mix; efficiency and profits often do. While the oil and water adage is well known to biodiesel producers — it means feedstock is contaminated with water — it also offers an opportunity. Biodiesel plant personnel are always looking for new tools and equipment that help a facility operate more ...

Parametric study of biodiesel quality and yield using a bench-top processor
Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

Assessment of the EU target on renewable energy for transport in the framework of the European vegetable oil sector
Biofuels is currently driving the interest in bioenergy sector. The recently issued Renewable Energy Directive (2009/28/EC) confirms the 10% target, set by the EC, for energy from renewable sources in transport. The European Union is the largest producer of biodiesel in the world and biodiesel is also the most important biofuel used in the EU. The aim of this paper is to investigate the biomass ...

Performance analysis of a single cylinder DI diesel engine using different biodiesel
Biodiesel produced from cottonseed oil is quite a promising alternative fuel for diesel engines. Use of vegetable oils in diesel engines leads to slightly inferior performance and higher smoke emissions due to their high viscosity and carbon residue. But the performance of vegetable oils can be improved by modifying them through the transesterification process. The research work discusses the ...

Honduras: Generating bioenergy from polluting waste ...
The idea came up during the latest Expobioenergía Workshop The baselines of this idea were drawn up during the Expobioenergía 2010 Workshop, “at some stage of the tour we made of the various companies and projects we had the chance to visit during the event”, explains Julio César Lucas, a member of the Honduran firm Quimys’ Oil S. de R.L. Following its ...

Biodiesel production from high FFA crude rice bran oil and investigation on its properties as CI engine fuel
This study is an attempt to convert high free fatty acid (FFA) crude rice bran oil (CRBO) into biodiesel and to evaluate whether the biodiesel obtained meets the biodiesel quality standards prescribed by ASTM D 6751-07b. CRBO was subjected to a two-step transesterification process using HCl and NaOH as acid and base catalyst respectively with a 15% v/v of methanol to oil ratio. This process ...

Process optimisation of base catalysed transesterification of Karanja oil for biodiesel production
Biodiesel has been receiving increasing attention due to its renewable nature, lower pollution potential and green house gas benefit compared to mineral diesel. There are numerous factors, which affect the yield of biodiesel in a transesterification process such as reaction temperature, molar ratio of alcohol to oil, catalyst concentration, stirring speed, reaction time, etc. These variables are ...

Combustion, performance and emission characteristics of a DI CI engine using biodiesel with varied fatty acid composition
Five Biodiesel produced from different vegetable oils were tested on a diesel engine to study the effect of biodiesel fatty acid composition specifically unsaturated composition on the engine combustion. The results from fuel analysis show that biodiesel (93% unsaturated fatty acid ester composition) with 55% linolenic ester has a higher density of 0.89 kg/m³, lower viscosity of 3.8 cSt, heating ...

Biodiesel fuel for transportation: Status and issues in the United States
The United States consumed 3.39 billion barrels of gasoline, 1.54 billion barrels of diesel fuel, and 0.59 billion barrels of jet fuel in 2007. And it currently imports 3.66 billion barrels of oil and petroleum products per year, 65% of US consumption, compared to 1.71 billion barrels (or 36%) 20 years ago. To address the growing gap between petroleum consumption and domestic production, the US ...
