Zeolite - Wikipedia

26/09/2002  Synthetic zeolites, like other mesoporous materials (e.g. MCM-41), are widely used as catalysts in the petrochemical industry, such as in fluid catalytic cracking and hydrocracking. Zeolites confine molecules into small spaces, which causes changes in their structure and reactivity. The acidic forms of zeolites prepared are often powerful solid-state solid acids, facilitating a host of acid ...

Petrochemistry - Wikipedia

Catalytic cracking is when a catalyst is being used. The plant where these operations are conducted is called a 'cracker'. Once these operations complete, new products are obtained that serve as building blocks of the petrochemical industry: olefins, i.e., mainly ethylene, propylene, and the so-called C4 derivatives, including butadiene—and aromatics, so called because of their distinctive ...

Chemical reactor - Wikipedia

Particularly in high-temperature petrochemical processes, catalysts are deactivated by processes such as sintering, coking, and poisoning. A common example of a catalytic reactor is the catalytic converter that processes toxic components of automobile exhausts.

Fluid catalytic cracking - Wikipedia

The first commercial use of catalytic cracking occurred in 1915 when Almer M. McAfee of Gulf Refining Company developed a batch process using aluminum chloride (a Friedel Crafts catalyst known since 1877) to catalytically crack heavy petroleum oils.

Catalysis - Wikipedia

Catalysis (/ kəˈtæləsɪs /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst (/ ˈkætəlɪst /). Catalysts are not consumed in the catalyzed reaction but can act repeatedly. Often only very small amounts of catalyst are required.

Industrial catalysts - Wikipedia

The most common catalysts used in the water-gas shift reaction are the high temperature shift (HTS) catalyst and the low temperature shift (LTS) catalyst. The HTS catalyst consists of iron oxide stabilized by chromium oxide, while the LTS catalyst is based on copper.

CATALYSTS IN THE PETROCHEMICAL INDUSTRY

The hydrocarbons are mixed with a very fine catalyst powder. These days the catalysts are zeolites (complex aluminosilicates) - these are more efficient than the older mixtures of aluminium oxide and silicon dioxide. The whole mixture is blown rather like a liquid through a reaction chamber at a temperature of about 500°C.

Hydrogenation - Wikipedia

In petrochemical processes, hydrogenation is used to convert alkenes and aromatics into saturated alkanes (paraffins) and cycloalkanes (naphthenes), which are less toxic and less reactive. Relevant to liquid fuels that are stored sometimes for long periods in air, saturated hydrocarbons exhibit superior storage properties.

Dehydrogenation - Wikipedia

Light olefins, such as butenes, are important raw materials for the synthesis of polymers, gasoline additives and various other petrochemical products. The cracking processes especially fluid catalytic cracking and steam cracker produce high-purity

Transalkylation - Wikipedia

Transalkylation, as used by the petrochemical industry, is often used to convert toluene into benzene and xylenes. This is achieved through a disproportionation reaction of toluene in which one toluene molecule transfers its methyl group to another one. The reaction is not selective, and the xylene produced can be ortho, meta, or para.

Boron - Wikipedia

Boron trifluoride is used in the petrochemical industry as a catalyst. The halides react with water to form boric acid. Boron is found in nature on Earth almost entirely as various oxides of B (III), often associated with other elements. More than one hundred borate minerals contain boron in oxidation state +3.
