Hydrodesulfurization (HDS), also called hydrotreatment or hydrotreating, is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. [1][2][3] The purpose of removing the sulfur, and creating products such as ...
Fluid catalytic cracking. A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products. [1][2 ...
ART is a leading supplier of hydroprocessing catalysts, with a portfolio of distillate hydrotreating, fixed bed resid hydrotreating, and ebullated bed resid hydrocracking catalysts.
Hydroprocessing. Hydroprocessing is a catalytic term relating to the processes of hydrocracking and hydrotreating. [1] These process are for the removal of sulfur, oxygen, nitrogen and metals from crude oil, this is done in the refining of fuel to enable lower sulfur levels in fuels. [2][3][4][5]
Hydrodeoxygenation (HDO) is a hydrogenolysis process for removing oxygen from oxygen-containing compounds. Typical HDO catalysts commonly are sulfided nickel - molybdenum or cobalt -molybdenum on gamma alumina. An idealized reaction is: [1] The first review on HDO was published in 1983. [2] HDO is of interest in producing biofuels, which are ...

Fischer–Tropsch process. Appearance. The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of ...
Catalytic reforming. Catalytic reforming is a chemical process used to convert naphthas from crude oil into liquid products called reformates, which are premium "blending stocks" for high-octane gasoline. The process converts low-octane linear hydrocarbons (paraffins) into branched alkanes (isoparaffins) and cyclic naphthenes, which are then ...
