  • Patent number: 7880046
    Abstract: Water reacts on molecular sieve catalysts used in oligomerization reactions and forms oxygenated compounds, in particular organic acids that may cause corrosion problems downstream of the reactor, in particular in distillation tower overhead systems and downstream thereof. A lowering of the presence of water in the feed prior to contacting thereof with the molecular sieve brings a significant reduction in corrosion downstream. At the same time, it has a significant beneficial effect on catalyst activity and brings a significant extension of catalyst life. Lowering water in the feed is particularly effective when organic nitrogen-containing Lewis bases are present in the feed, even at low levels.

  • Patent number: 7875754
    Abstract: A method of operation for producing high yield of alkylate product using catalytic reactors. The catalytic reactors which cycle between reaction mode and catalyst regeneration mode have their contents exchanged with each other at the beginning of each cycle in order to increase the yield of the desired product. This exchange increases the yield by minimizing the contact of reactant in reaction mode with regenerant utilized in regeneration mode. Thus, reducing/preventing the undesirable alternate reaction between the two, which consumes the reactant making it unavailable for the production of the desired product.
