With gasoline prices volatile and the Obama administration committed to easing the United States’ addiction to oil, Americans seem to be taking more interest in alternative fuels, including those derived from farm crops and other renewable organic sources. Among the most widely available are biodiesel and vegetable oil, both of which can be used to … Read More

With the extension of human history, natural resources will only decrease and not increase. Seeing the rising world crude oil prices, countries are actively looking for alternative energy sources, especially renewable energy production and manufacturing methods. Following the successive development of solar energy, alcohol and other alternative energy sources, biodiesel has also begun to emerge … Read More

In 1983, Graham Quick, an American scientist, successfully applied methyl ester of flaxseed oil prepared by transesterification reaction to diesel engine for the first time, and proposed the concept of biodiesel, which was defined as renewable fatty acid monoester. Biodiesel can be mixed with petrochemical diesel in any proportion. It is a good substitute for … Read More

It is often argued that the EU biofuels policy drives prices for agricultural feedstock, yet there is nothing to prove this. When prices for agricultural commodities and staple foods exploded globally in 2007 and 2008 and prices became volatile as a result, the focus was on issues surrounding global nutrition. Continued famine and poverty since … Read More

Raw material is the key to produce biodiesel. In the process of preparing biodiesel, raw material cost accounts for more than 70% of the total cost. Therefore, in the process of preparing biodiesel, searching for large-scale, low-cost, pollution-free and high-utilization raw oil is the core and key problem to be solved in the industrialization of … Read More

Fuel and food production are mutually exclusive Although the development of biodiesel as an alternative energy source has been favored by the industry, there are few examples of commercial production. This comes mainly from the cost of vegetable oil. Vegetable oil procurement, transportation, storage and extraction account for most of the cost of biodiesel production. … Read More

Biodiesel is a renewable, clean-burning diesel replacement that is reducing U.S. dependence on foreign petroleum, creating jobs and improving the environment. Made from a diverse mix of feedstocks including recycled cooking oil, soybean oil, and animal fats, it is the first and only EPA-designated Advanced Biofuel in commercial-scale production across the country and the first … Read More

An example of a simple production flow chart is proved below with a brief explanation of each step. Mixing of alcohol and catalyst The catalyst is typically sodium hydroxide (caustic soda) or potassium hydroxide (potash). It is dissolved in the alcohol using a standard agitator or mixer. Reaction. The alcohol/catalyst mix is then charged into … Read More

In the international market, some countries and regions in the United States, Europe and Asia have begun to establish commercial biodiesel production bases and widely use biodiesel as alternative fuels. Austria Austria is the first country in the world to esterify vegetable oils. Its annual production capacity is about 550,000 t/a. Its main market for … Read More

Significance of Developing Bioenergy: As a global limited strategic resource, petroleum is non-renewable. The greater the dependence on its import, the greater the risk, and even endangers the national energy strategic security. Therefore, finding new energy, especially renewable energy, is an urgent issue facing all countries. In view of the limited petroleum resources in China, … Read More
