“If you want to know more about oil, please click” The main raw materials of biodiesel are vegetable oil (rapeseed oil ,soybean oil ,peanut oil, corn oil ,cotton seed oil ,etc),animal oil(fish oil, lard oil, beef tallow, mutton fat,etc),wast oil or microbial oil. Biodiesel is a typical “green energy“,it has the characteristics of good … Read More

Biodiesel can be used as a fuel for boilers, turbines, diesel engines, etc., and The main application in the industry is fatty acid methyl esters. Biodiesel is a kind of high-quality clean diesel that can be extracted from various biomasses. Therefore, it can be said that it is an inexhaustible source of energy. In today’s … Read More

Introduction Glycerol (also known as glycerin) is a major byproduct in the biodiesel manufacturing process. In general, for every 100 pounds of biodiesel produced, approximately 10 pounds of crude glycerol are created. As the biodiesel industry is rapidly expanding, a glut of crude glycerol is being created. Because this glycerol is expensive to purify for … Read More

Introduction Biodiesel production does not result in a lot of waste. However, depending on the process and feedstocks use, it can produce some wastewater, minerals, resins, solids strained out of used oil and glycerin. Often, waste is not an issue for large producers because they can invest in the equipment needed to recycle and reuse … Read More

Introduction Commercial-scale biodiesel producers have many constraints beyond those which small producers need to meet. Commercial producers must satisfy the expectations of owners and/or stockholders for profitability. They must make optimal use of capital and other resources. They also have to include the cost of labor because it comes from paid employees. Small-scale producers will … Read More

Do you know that energy in the oil from oilseed crops, algae, restaurant waste oil, and animal fat can serve as a biodiesel feedstock? This article explores many feedstocks that make oil, which can be used in biodiesel production. Harvesting soybeans in Nebraska.  Photo: F. John Hay, Extension Educator, University of Nebraska-Lincoln Extension. Contents Oilseed Crops for … Read More

Biodiesel refers to a vegetable oil – or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, ethyl, or propyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, soybean oil, animal fat (tallow)) with an alcohol producing fatty acid esters. Biodiesel is meant to be used in standard diesel engines and … Read More

Microalgae biodiesel and by-products must be separated for increasing the biodiesel production. The main separation processes used hot water (50?C) (Li et al., 2007), organic solvents such as hexane (Halim et al., 2010; Wiltshire et al., 2000) and water-organic solvent for a liquid-liquid separation (Couto et al., 2010; Lewis et al., 2000; Samorì et al., … Read More

The direct use of crude vegetable oils in diesel engines is envisageable, but could lead to numerous technical problems. For example, their characteristics (high viscosity, high density, difficulty to vaporize in cold conditions) cause deposits in the combustion chamber, with a risk of fouling and an increase in most emissions (Basha et al., 2009). These … Read More

Widely applicable biodiesel and low cost. Biodiesel is applicable as fuel oil in diesel engine, but also mixing with diesel at any ratio. Biodiesel technology can reduce human dependence on oil energy, solve problem of diesel exhaust emission essentially, improve air pollution and protect environment. This superior biodiesel technology is widely applied in biodiesel preparing … Read More
