How sulfur is removed from fossil fuel?
Sulfur is removed from fossil fuels through a process called desulfurization. This can involve methods like hydrodesulfurization, which uses hydrogen to convert sulfur compounds into hydrogen sulfide, which can then be captured and removed. Alternatively, flue gas desulfurization can be used to remove sulfur dioxide from the emissions produced when fossil fuels are burned.
Can diesel fuel be cracked AND IF SO WHAT ARE THE END PRODUCTS?
Diesel fuel can be cracked through a process called hydrotreating, which involves breaking down the larger hydrocarbon molecules in diesel into smaller ones. The end products of this process can include lighter hydrocarbons like gasoline, as well as some by-products such as naphtha and gas.
Flow process to produce white spirit?
White spirit is typically produced by the distillation of crude oil or by the treatment of a mixture of hydrocarbons. The process involves distilling the crude oil in a fractionating column to separate the white spirit fraction based on boiling points. The fraction is then further refined through processes such as solvent extraction and hydrotreating to remove impurities and improve quality.
What is the abbreviation of potential difference?
The abbreviation of potential difference is V, which stands for voltage.
What is the electronegativity difference in Na2 O?
The electronegativity difference in Na2O is calculated by finding the difference between the electronegativity values of the two elements. Sodium (Na) has an electronegativity of approximately 0.93, and oxygen (O) has an electronegativity of approximately 3.44. Therefore, the electronegativity difference in Na2O is 3.44 - 0.93 = 2.51.

What is the meaning of hydro treated light nephthanic distillate?
Hydrotreated light naphthenic distillate is a refined petroleum product obtained through the hydrocracking and hydrotreating processes. It consists primarily of naphthenic hydrocarbons and is characterized by its low aromatic content, making it suitable for use in high-performance lubricants, solvents, and fuel additives. The hydroprocessing reduces impurities and enhances the product's stability and environmental compliance. This type of distillate is valued for its excellent solvency and low volatility properties.
Whats hydrogen used for?
Its used for processing foods. Hydrogen is used in massive quantities in the petroleum and chemical industries. In a petrochemical plant, hydrogen is used for hydrodealkylation, hydrodesulfurization, and hydrocracking, all methods of refining crude oil for wider use. In the food industry, hydrogen is used to hydrogenate oils or fats, which permits the production of margarine from liquid vegetable oil. Hydrogen is used to produce Methanol and hydrochloric acid, as well as being used as a reducing agent for metal ores.
Is diesel fuel renewable or not?
No, diesel is a petroleum based product, from oil, so it is not renewable.However, bio-diesel is now being manufactured from plant oil. This is renewable. Diesel engines will also run on recycled cooking oil, mostly from restaurants.Read the related questions below.

Can disulfide oil be mixed with fuel oil?
Mixing disulfide oil with fuel oil without further sulfur treating is potentially undesireable as combustion leads to the production of sulfur-containing pollutants. Disulfide oils are generally produced as byproducts of gas sweetening--a process where sulfur is removed from liquid petroleum gas (LPG). Separating disulfide oil into hydrocarbons (oil) and sulfur (disulfide) requires hydrotreating. After hydrotreating, the hydrocarbons can be blended with other fuel oils.
What is refine oil?
Oil refining is the process of distilling oil and then further reforming, catalytic cracking, hydrofining, blending, and sometimes coking, hydrocracking, alkylating various fractions of the distilled oil.
What is the effect of olefin concentration on naphtha hydrotreating process?
Hydrotreating reaction is an exothermic reaction. The total reaction provides excess reaction heat; more is produced by the exothermic hydrogenation reactions than are required to support the endothermic cracking reactions.High Olefin conc. leads to high temp. rise due to hydrogenation reaction.This excess heat increases the reactor temperature and accelerates the reaction rate. Temperature rise can be controlled by injecting cold hydrogen or cold recycled quench into the reactors to absorb excess reaction heat.
How do you convert kerosene into diesel?
Kerosene can be converted into diesel through a process called hydrocracking. This involves breaking down the larger molecules in kerosene into smaller ones to create a product that is more similar to diesel fuel. The process requires high temperatures, pressure, and catalysts to transform the chemical composition of the kerosene.
How sulfur is removed from fossil fuel?

What catalyst is used to separate sulfur from oil?
Hydrogenation catalysts, such as nickel or cobalt, are commonly used to remove sulfur from oil through a process called hydrodesulfurization. This process involves breaking down sulfur compounds in the presence of hydrogen to form hydrogen sulfide, which can then be removed.
Is there a use for residue after gasoline is extracted from crude oil?
Yes, the residue left after extracting gasoline from crude oil can be used as feedstock for producing products like asphalt, lubricating oils, and waxes. Additionally, residue can be processed further into lighter fuels through techniques like coking or hydrocracking.
