Introduction Biodiesel that leaves the production plant in good condition can become unacceptable during distribution without proper care and attention. Biodiesel can degrade due to oxidation, contact with water, and/or microbial activity. In general, biodiesel will degrade more quickly than petro-diesel. In one sense, this is a good thing: a biodiesel spill will biodegrade quickly … Read More

Introduction Although the biodiesel manufacturing process is fairly straightforward, there are several aspects of biodiesel production that need careful attention to detail for a productive, safe, and environmentally sound practice. First, some chemicals used could pose serious risks to the operator or to the environment, unless the proper precautions are taken for storage, process safety, … Read More

Introduction Biodiesel is a relatively safe product. It is considered nonflammable and biodegradable. However, the components to make biodiesel can be hazardous in some situations. Biodiesel is made by reacting vegetable oil or animal fat with an alcohol (methanol or ethanol) and a catalyst (sodium hydroxide or potassium hydroxide). Sulfuric and hydrochloric acids are also … Read More

In the 1970s, the petroleum oil embargo caused many countries to look to vegetable oil as a possible fuel. Scientists in Austria, the United States, South Africa, and many other countries rediscovered that straight vegetable oil could be used to run diesel engines; however, eventually the poor quality of the fuel spray caused by the … Read More

Biodiesel can be produced from a wide variety of oilseed crops and animal fats. In Europe, rapeseed oil is the major biodiesel feedstock. In the United States, soybeans are the dominant biodiesel feedstock. Soybeans Soybeans produce approximately 1.5 gallons of oil per bushel. U.S. farmers produced a record-breaking yield in 2009 of 44 bushels per acre. This … Read More

With the increasing demand for energy in cities and the depletion of petroleum resources, the whole world will face the crisis of energy shortage. Moreover, petroleum combustion causes serious pollution to the environment, which affects people’s health to a great extent. Therefore, the research and application of biodiesel has become the focus of alleviating the … Read More

Lubricating oil is the most widely used lubricant on a variety of engines. Its role is to: lubrication, cooling, protection, cleaning. Gear oil, also known as transmission oil, is mainly used to lubricate various gears of transmissions, reducers and differentials in automobiles and tractor transmission systems. The viscosity of gear oils is larger than that … Read More

Following China’s ban on U.S. soybeans, the U.S. has been in need of new buyers. The EU-28 benefits from this situation as its imports of U.S. soybeans have multiplied. The EU-28 has always depended on oilseed imports from third countries, because EU demand exceeds EU production by around 30 percent. Above all, soybeans are in strong … Read More

According to a new analysis commissioned by the Union of Concerned Scientists and conducted by independent research firm Cerulogy on the availability of low-carbon fuels to meet a Washington State clean fuels program, the state can reduce the carbon intensity of transportation fuels by 11.2 percent by 2028. Transportation is the largest source of carbon emissions in … Read More

Biodiesel facts Biodiesel is made from vegetable oil or animal fat (triglycerides) reacted with methanol or ethanol and a catalyst (lye), yielding biodiesel (fatty acid methyl or ethyl esters) and glycerin as a by-product. It can be used in any diesel engine without modifications — diesel engines run better and last longer with biodiesel. And … Read More
