  2. Alkylation unit - Wikipedia

    en.wikipedia.org/wiki/Alkylation_unit

    Alkylation unit in a refinery, line width corresponds approximately to the mass flow (SAAU technology) The first alkylation units entered in service in 1940. In 2009 around 1,600,000 barrels per day of capacity were installed worldwide, [5] with an equal share of 800,000 barrels per day for SAAU and HFAU technologies. On the 1st January 2016 ...

  3. Alkylation - Wikipedia

    en.wikipedia.org/wiki/Alkylation

    Alkylation is a chemical reaction that entails transfer of an alkyl group. The alkyl group may be transferred as an alkyl carbocation , a free radical , a carbanion , or a carbene (or their equivalents).

  4. Forster–Decker method - Wikipedia

    en.wikipedia.org/wiki/Forster–Decker_method

    The Forster–Decker method is a series of chemical reactions that have the effect of mono-alkylating a primary amine (1), forming a secondary amine (6). [1] [2] The process occurs by way of transient formation of an imine (3) that undergoes the actual alkylation reaction.

  5. Linear alkylbenzene - Wikipedia

    en.wikipedia.org/wiki/Linear_alkylbenzene

    The DETAL process involving dehydrogenation of n-paraffins to olefins, and subsequent reaction with benzene using a fixed bed catalyst. This is newer technology and has several of the stages depicted in the HF/n-paraffins process, but it is principally different in the benzene alkylation step, during which a solid-state catalyst is employed.

  6. Fluid catalytic cracking - Wikipedia

    en.wikipedia.org/wiki/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.

  7. Cumene process - Wikipedia

    en.wikipedia.org/wiki/Cumene_process

    First stage of Hock process: alkylation of benzene with propylene. Second stage of Hock process: autoxidation of cumene. The cumene process (cumene-phenol process, Hock process) is an industrial process for synthesizing phenol and acetone from benzene and propylene. The term stems from cumene (isopropyl benzene), the intermediate material ...

  8. World Bank Projects Leave Trail of Misery Around Globe

    projects.huffingtonpost.com/projects/worldbank...

    In Kenya, the World Bank's in-house Inspection Panel found the bank violated its policies by failing to do enough to protect the Sengwer, an indigenous minority group in Kenya's western forests. Over the past decade, the World Bank has regularly failed to enforce its

  9. Transalkylation - Wikipedia

    en.wikipedia.org/wiki/Transalkylation

    Transalkylation reactions of six to ten carbon methylated aromatics are often performed with the cofeed of hydrogen gas, over a zeolite based solid catalyst. Industrial processes operate the transalkylation reactor at elevated temperature and pressure to achieve desired process economics.
