The uses and peculiarities of D2 diesel

by Sanjeev Yadav SEO Consultant

The fuel diesel is a special type of liquid fuel which is commonly used in the diesel engines where the ignition process takes place without any actual spark. These specially designed engines are used widely in various fields in order to increase the thermodynamic efficiency and fuel efficiency. There are various types of diesel fuel which are obtained by fractional distillation of petroleum. In some cases, the diesel collected using this process is also known as petrodiesel.

How to obtain diesel?

The fuel can be obtained from various sources namely, petroleum, biomass, fat collected from the body of various animals, biogas and other types of natural gases and most importantly, coal liquefaction. In the case of petrodiesel, the fuel is produced using the method fractional distillation. The crude oil is processed between the temperatures ranging from 200° C to 350° C atm pressure.

Comparison between D1 and D2

All diesel cars run on diesel 2 or D2 fuel under normal conditions. Diesel 2 is more volatile than Diesel 1 as it contains a higher cetane number. Diesel 2 (D2) provides greater fuel economy than Diesel 1 (D1). Diesel fuel, like any other oil fuel, gets thicker and cloudier when the temperatures reduce. Diesel 2 (D2) in comparison to Diesel 1 (D1) is less liquid when the temperatures are extremely low and hence is more efficient in comparison to the two-grade diesel fuels.

Types of diesel:

Coming to the types of D2 Diesel available in the market which can be classified as:

• Synthetic Diesel

This type of diesel is produced from carbonaceous material like biomass, natural gases, coal, etc. After gasifying the raw material into a form of synthetic gas, the gas is purified, liquefied and collected using the Fischer–Tropschmethod. The liquid hence collected is known as the synthetic diesel. In this process, the transformation of the raw materials into synthetic diesel depends entirely on the material which you are using. Generally, the paraffin diesel has a very low percentage of sulphur and aromatics.

• Bio-Diesel

The product bio-diesel or FAME is produced using various vegetable oils and fats of the animals. The biolipids are first transferred into methanol which further undergoes processing to form bio-diesel. The process of transesterification requires catalysts like Sodium Hydroxide which helps in easy conversion of the vegetable oils and methanol to form FAME leaving behind by-products like glycerin and water. This diesel fuel is very eco-friendly and has the ability to reduce the number of health risks.

• Di-Methyl Ether Diesel

This is a special diesel prepared using chemical methods is considered due to its clean combustion characteristic. The DME produces checked amount of soot and emits a very nominal amount of nitrogen oxides.

Uses of diesel fuel

With increased demand for this fuel, several D2 diesel exporters in the US have emerged. Diesel is a very popular form of petroleum fuel used widely as it produces very little amount of sulphur when combusted. As per the U.S. Energy Information Administration, the use of diesel constitutes about seven per cent of the energy use in the U.S. alone. It is used in vehicles, power generation, running heavy equipment, etc.
