Diesel
Diesel is produced from the fractional distillation of crude oil between 200 °C and 400 °C resulting in a mixture of carbon chains and is composed of saturated and aromatic hydrocarbons.
The principal measure of Diesel fuel quality is its cetane number. A higher cetane number indicates that the fuel ignites more readily when sprayed into hot compressed air.
Diesel fuel is widely used in most types of transportation, exclusively for the combustion engines of self-powered rail vehicles, tractors, power generation, pump sets and in various other diesel engine driven applications.
Naphtha
Naphtha is a highly flammable liquid hydrocarbon mixture. It contains paraffins, cycloalkanes, and aromatic compounds.
Naphtha is produced from coal tar, tar sands, and shale deposits.
Naphtha is used as a fuel, solvent, and component of technological processes in industrial enterprises.
Petroleum Coke
Petroleum Coke is a coke what derives from the final cracking process, that takes place in a unit called delayed coker unit. The chemical and physical characteristics of petroleum coke depend on the used crude oil composition and the refining process. Physically petroleum coke can resemble into large or smaller black pieces with a porous feel.
As its heating value is higher than coal’s, it can be used as a heating material in industrial environments. Fuel grade petroleum coke produces no visible ash when burned. Petroleum coke is an extremely stable fuel which means there is little risk of combustion during transportation, and it can be stored on a long term without any difficulties.
