    en.wikipedia.org/wiki/Citybook_I:_Butcher,_Baker...

    Citybook I: Butcher, Baker, Candlestick Maker is a role-playing game supplement published by Flying Buffalo in 1982 as part of their Catalyst series of game aids for any role-playing game system. It was written by Steve Crompton , and includes information on how to use typical medieval urban businesses in role-playing encounters.

  3. Activated alumina - Wikipedia

    en.wikipedia.org/wiki/Activated_alumina

    Activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 m 2 /g. The compound is used as a desiccant (to keep things dry by adsorbing water from the air) and as a filter of fluoride , arsenic and selenium in ...

  4. Haber process - Wikipedia

    en.wikipedia.org/wiki/Haber_process

    The Haber process, [1] also called the Haber–Bosch process, is the main industrial procedure for the production of ammonia. [2] [3] It converts atmospheric nitrogen (N 2) to ammonia (NH 3) by a reaction with hydrogen (H 2) using finely divided iron metal as a catalyst:

  5. Catalyst (role-playing game supplements) - Wikipedia

    en.wikipedia.org/wiki/Catalyst_(role-playing...

    Catalyst is a series of fantasy role-playing game supplements created by Flying Buffalo as a series of game aides that could be used with any medieval fantasy-themed role-playing game system. The first supplement, Grimtooth's Traps , was released in 1981.

  6. Industrial catalysts - Wikipedia

    The first step in the WGS reaction is the high temperature shift which is carried out at temperatures between 320 °C and 450 °C. As mentioned before, the catalyst is a composition of iron-oxide, Fe 2 O 3 (90-95%), and chromium oxides Cr 2 O 3 (5-10%) which have an ideal activity and selectivity at these temperatures.

  7. Monsanto process - Wikipedia

    en.wikipedia.org/wiki/Monsanto_process

    The catalytic cycle of the Monsanto process. The catalytically active species is the anion cis-[Rh(CO) 2 I 2] − (top of scheme). [3] The first organometallic step is the oxidative addition of methyl iodide to cis-[Rh(CO) 2 I 2] − to form the hexacoordinate species [(CH 3)Rh(CO) 2 I 3] −.

  8. Selective catalytic reduction - Wikipedia

    en.wikipedia.org/wiki/Selective_catalytic_reduction

    In marine applications, this can increase fresh water requirements as the boiler must be continuously washed to remove the deposits. Most catalysts on the market have porous structures and a geometries optimized for increasing their specific surface area (a clay planting pot is a good example of what SCR catalyst feels like). This porosity is ...

  9. Aliquat 336 - Wikipedia

    en.wikipedia.org/wiki/Aliquat_336

    Aliquat 336 is used as a phase transfer catalyst, [2] including in the catalytic oxidation of cyclohexene to 1,6-hexanedioic acid. [3] This reaction is an example of green chemistry, as it is more environmentally friendly than the traditional method of oxidizing cyclohexanol or cyclohexanone with nitric acid or potassium permanganate, which produce hazardous wastes.
