Eugene Houdry, not Alex Oblad is generally credited with inventing Catalytic Cracking. See what the American Chemical Society has to say: http://acswebcontent.acs.org/landmarks/landmarks/hdr/index.html You may also check the following reference, that was quoted by the ACS article: Alex Oblad. "The Contributions of Eugene J. Houdry to the Development of Catalytic Cracking." In Heterogenous Catalysis: Selected American Histories, ed. by Burtron H. Davis and William P. Hettinger (Washington, DC: American Chemical Society, 1983): 61-75.

  1. should we bring the section on cracking mechanism from the alkane page over here?
  2. need to include info on hydrocracking done --71.115.209.156 01:33, 16 Jun 2005 (UTC)
  3. more details needed on process chemistry, mechanism, side reactions, thermodynamics and kinetics (would that be too much for an encyclopedia article?) --Unconcerned 10:23, 25 Feb 2004
  4. should the Steam_cracking and pyrolysis pages be combined with this page? 131.203.9.226 17:13, 24 Aug 2004
Steam cracking is what the average refiner would call pyrolysis, while pyrolysis probably refers to the more general usage of the term; so yes, I think steam cracking should be merged and a redirect left in place; while pyrolysis updated to include a link to cracking (chemistry). Would you please consider contributing with some of the things above? At this moment I do not have the necessary time to edit the 'pedia :-( --Unconcerned 03:54, 26 Aug 2004 (UTC) done --71.115.209.156 01:06, 16 Jun 2005 (UTC)

Article has a lot of very specific information, but no citations.

The primary catalytic material in modern FCC catalyst is Y-type zeolite, which is a special geometric structure composed of silicon and aluminum oxides. Other catalytic components incorporated into FCC catalysts include high surface area alumina, acidic clays and various additives that control sulfur levels in the cracked product, sometimes other additives that help promote CO oxidation during catalyst regeneration, and still others that moderate the deliterious impact of nickel and vanadium on cracked product yields.Chem engineer 19:25, 21 January 2007 (UTC)

...is this this best image we have? A Soviet unit from 1934? WTF. —Preceding unsigned comment added by 192.149.93.63 (talk) 17:20, 26 March 2008 (UTC)
