Safe Chemical Handling in Biodiesel Production

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

Biodiesel Production Principles and Processes

The process to make biodiesel involves a chemical reaction. This means that the biodiesel industry is a chemical industry. Those involved in making biodiesel must have a good understanding of the underlying chemistry to ensure they are making quality fuel in a safe manner. Biodiesel is an alternative fuel for diesel engines that is produced … Read More

Value-added uses for crude glycerol–a byproduct of biodiesel production

Glycerol is a by-product of biodiesel, soap and fatty acid manufacturing plants, which are now facing sustainability threats and a reduction in prices in the market due to its oversupply as a result of the rapid expansion of biodiesel plants all over the world. The global production and consumption of glycerol, as well as demand … Read More

What are the advantages and disadvantages of biodiesel?

Advantage: (1) The performance of biodiesel is very similar to that of petroleum diesel. As the fuel of diesel engine, there is no need to modify the engine and the storage of biodiesel is the same as that of petroleum diesel. (2) Biodiesel used as automobile fuel can reduce emissions of carbon dioxide (CO2) by … Read More

What is the production principle of biodiesel?

There are two methods of production, physical synthesis and chemical synthesis. 1. Chemical synthesis of biodiesel: The chemical synthesis method is to transesterify low-carbon alcohols (mainly methanol or ethanol) with natural oils and fats. After transesterification, long-chain fatty acid esters of low-carbon alcohols can be obtained. The relative molecular weight of the esters can be reduced … Read More

Recent developments in global biodiesel

Biodiesel refers to regenerative diesel fuel that can be used as a feedstock oil, such as oil crops, wild oil plants and engineering microalgae, as well as animal fats and catering waste oils. Compared with traditional diesel, biodiesel has obvious advantages in many aspects such as economy and environmental protection. Hydrogenated fats, petroleum, and animal … Read More

Biodiesel Production in the USA

Biodiesel production in the USA can be divided into three (3) different layers. Each layer has its own characteristics, problems and opportunities. Commercial producers These large scale producers have annual capacities of more than 2 million liters biodiesel per year (2000 MT/year). Cooperative and community producers These smaller scale producers have annual capacities from 40,000 … Read More

Brazil’s ECB Group to build renewable diesel complex in Paraguay

A first-of-its-kind renewable diesel project in South America has moved one step closer to construction. Paraguay President Mario Abdo Benítez and Erasmo Carlos Battistella, president of Brazilian investment holding company ECB Group, met at Palacio de los López where a memorandum of understanding was signed Feb. 25 to continue ECB Group’s investments in Paraguay. The … Read More

Research and application status of biodiesel (II)

Research progress of production methods Direct mixing method The direct mixing method is to mix vegetable oil and mineral oil in a certain proportion and use them directly as engine fuel. The results show that vegetable oil has good dynamic and overload performance and high thermal efficiency when used directly in internal combustion engines. However, … Read More
