Powerformer is a 3-phase AC generator with a rotor of conventional design. The difference compared with conventional generator lies in the stator windings. In Powerformer stator winding consists of high-voltage cables instead of today's windings with a square cross-section.
Also known as: platformate. Reformate is the primary output of the catalytic reformer. The primary use of reformate is as a high-octane blend stock for making gasoline. Reformate's high octane comes from the high levels of aromatics that it contains.
The purpose of a hydrotreater unit is primarily to remove sulfur and other contaminants from intermediate streams before blending into a finished refined product or before being fed into another refinery process unit.
Catalytic reforming. Catalytic reforming is a chemical process used to convert petroleum refinery naphthas distilled from crude oil (typically having low octane ratings) into high-octane liquid products called reformates, which are premium blending stocks for high-octane gasoline.
Fuel grade petcoke is typically very high in heating value (BTUs per pound), produces virtually no ash when burned, and is most commonly used in electric power plants and cement kilns. As a carbon source, petroleum coke is used to manufacture: Energy. Steel.
Naphtha: Naphtha falls between gasoline and kerosene for combustibility. It is used in petroleum fuels, but also as paint thinner and feedstock for manufacturing plastics. It is a byproduct of petroleum fuel and natural gas processing, and naturally occurs as a gas, becoming liquid under pressure.
4. Hydrocracking. The dehydrogenation reactions are very endothermic, requiring the hydrocarbon stream to be heated between each catalyst bed. While thermal reforming could produce reformate with octane numbers of 65 to 80 (depending on the yield), catalytic reforming increases the octane numbers to around 90 to 95.
Platforming is herein defined as a catalytic reforming process in which a hydrocarbon fraction containing naphthenes and paraffins and boiling in the gasoline boiling range is contacted in the vapor phase and in the presence of a substantial pressure of hydrogen with a catalyst containing platinum on a suitable support
Reformate is a gasoline blending stock that is produced by the catalytic reforming, a refining process in which mixed-catalysts and hydrogen promote the rearrangement of lower octane naphthenes into higher octane compounds without a significant reduction in carbon number (Leffler, 2000).
Reformate. Also known as: platformate. Reformate is the primary output of the catalytic reformer. The primary use of reformate is as a high-octane blend stock for making gasoline. Reformate's high octane comes from the high levels of aromatics that it contains.
Steam reforming or steam methane reforming is a chemical synthesis for producing syngas (hydrogen and carbon monoxide) from hydrocarbons such as natural gas. This is achieved in a reformer which reacts steam at high temperature and pressure with methane in the presence of a nickel catalyst.
Thermal cracking is an extraction process in which hydrocarbons such as crude oil are heated to a high temperature to break the molecular bonds. In 1913, the thermal cracking process was developed, which subjected heavy fuels to both pressure and intense heat, physically breaking the large molecules into smaller ones.
Reform is defined as to correct someone or something or cause someone or something to be better. An example of reform is sending a troubled teenager to juvenile hall for a month and having the teenager return better behaved. YourDictionary definition and usage example.
Autothermal Reforming (ATR) is a process for producing syngas, composed of hydrogen and carbon monoxide, by partially oxidizing a hydrocarbon feed with oxygen and steam and subsequent catalytic reforming.
Thermal reforming alters the properties of low-grade naphthas by converting the molecules into those of higher octane number by exposing the materials to high temperatures and pressures. Catalytic reforming uses a catalyst, usually platinum, to produce a similar result.
Reforming. Reforming is a process designed to increase the volume of gasoline that can be produced from a barrel of crude oil. The other products of reforming are light gases and a high-octane gasoline blending component called reformate.
This is another treatment that is used to produce molecules that will raise the octane number of petrol. This process changes the shape of molecules rather than their size (as in cracking which makes smaller molecules). The starting material is naphtha, another fraction from the distillation of crude oil.
A hydrocracking unit, or hydrocracker, takes gas oil, which is heavier and has a higher boiling range than distillate fuel oil, and cracks the heavy molecules into distillate and gasoline in the presence of hydrogen and a catalyst.
9 Catalytic Reforming. Dehydrogenation reactions are endothermic, and as such, the hydrocarbon stream must be heated between each catalyst bed. The hydrocracking reaction is the only one that does not release hydrogen. Hydrogen can be used in the hydrotreating and hydrocracking processes.
Kerosene: This fuel has a lower freezing point and burns more slowly than some other fuels, such as gasoline. Naphtha: Naphtha falls between gasoline and kerosene for combustibility. It is used in petroleum fuels, but also as paint thinner and feedstock for manufacturing plastics.
Alkylate is the primary product of the alkylation unit, which converts light olefins (such as butylene) into a high-quality gasoline blendstock by reacting it with isobutane. However, alkylate can also be made from propylene and isobutane, or pentene and isobutane.
An octane rating, or octane number, is a standard measure of the performance of an engine or aviation fuel. The higher the octane number, the more compression the fuel can withstand before detonating (igniting). Use of gasoline with lower octane numbers may lead to the problem of engine knocking.
Process Description
The naphtha hydrotreater (NHT) is a feed pretreatment unit which removes contaminants from naphtha streams in order to protect the catalysts used in a range of downstream catalytic conversion processes such as benzene saturation, naphtha isomerisation and catalytic reforming.First because the sulfur dioxide resulting from fuel emissions reacts with oxygen and water vapor, becoming sulfuric acid and causing acid rains. Furthermore, even in very small quantities, sulfur can degrade the noble metals in the catalytic reforming process, which is used to improve octanes in petrol.
Catalytic - uses a catalyst to speed up the cracking reaction. Catalysts include zeolite, aluminum hydrosilicate, bauxite and silica-alumina. fluid catalytic cracking - a hot, fluid catalyst (1000 degrees Fahrenheit / 538 degrees Celsius) cracks heavy gas oil into diesel oils and gasoline.
Catalytic reforming is a major conversion process in petroleum refinery and petrochemical industries. It transforms low octane naphtha into high-octane motor gasoline blending stock and aromatics rich in benzene, toluene, and xylene with hydrogen and liquefied petroleum gas as a byproduct.
B/ Catalytic Cracking. Catalytic cracking, also called cat cracking, is the breaking of large molecules into smaller ones at elevated temperatures via the use of a catalyst. Additionally, the product from cat cracking is of a higher octane rating than the product obtained with thermal cracking.
