Patent number: 8314277Abstract: The service life and deactivation rate of a benzene saturation catalyst is improved through use of a new sulfur guard bed containing a chloride additive. This sulfur guard bed, which contains supported CuO material having an increased resistance to reduction, shows such improvement. Thus, the danger of run-away reduction followed by a massive release of water and deactivation of an isomerization catalyst is practically eliminated. The fact that the guard bed material preserves the active metal phase-copper in an active (oxide) form is an important advantage leading to very low sulfur content in the product stream. The sulfur capacity per unit weight of sorbent is also significantly increased, making this sorbent a superior cost effective sulfur guard product. The guard bed is effective in treating mixed phase feed streams.Type: GrantFiled: June 2, 2011Date of Patent: November 20, 2012

The catalysts may be prepared by slurrying a silica powder or impregnating a silica particle with a solution of a cobalt compound, cobalt amine carbonate, and aging the resulting slurry or solid at elevated temperature; the cobalt amine carbonate is decomposed and precipitated as basic cobalt carbonate onto the silica support. Preferably, the catalysts have a cobalt surface area in the range of 25 to >100 m2 per gram total cobalt. The catalyst may be used in hydrogenation reactions, Fischer-Tropsch reactions and oxidation reactions.Type: GrantFiled: July 26, 2002Date of Patent: March 18, 2003Assignee: Imperial Chemical Industries PLCInventors: Cornelis M Lok, Stephen Bailey, Gavin Gray

Patent number: 6432868Abstract: The invention concerns a catalyst comprising at least two group VIII metals, chlorine, fluorine, and at least one amorphous oxide matrix. The catalytic composition is such that the fluorine content is 1.5% by weight or more of the total catalyst mass. The invention also concerns the use of this catalyst in hydrogenating aromatic compounds contained in feeds comprising sulphurated compounds.Type: GrantFiled: November 9, 2000Date of Patent: August 13, 2002Assignee: Institut Francais du PetroleInventors: Nathalie Marchal-George, Slavik Kasztelan
