Publication number: 20100081566Abstract: Multimetallic anionic clays (MACs) are prepared using economical raw materials or reactants and a procedure for obtaining a series of multimetallic mixed oxides derived from the thermal decomposition of the MACs which comprises: (1) dissolving water-soluble bimetallic and/or trimetallic sources in water, (2) dispersing and homogenizing separate water-insoluble divalent and/or trivalent metal precursors with a high-speed stirrer in order to obtain small and reactive particles; depending on the nature of the water-insoluble divalent and/or trivalent metal precursors, this process can be adjusted to a desired pH, (3) adding the suspension obtained in (2) to solution (1) with the reaction medium still dispersed to facilitate solid particle's reduction/dissociation, and (4) afterwards the slurry is aged for several hours and finally dried. This process enables raw materials or reactants to be easily handled, and eliminates unit operations involving product washing and/or purification steps.Type: ApplicationFiled: December 4, 2009Publication date: April 1, 2010Applicant: INSTITUTO MEXICANO DEL PETROLEOInventors: Jaime Sanchez-Valente, Esteban Lopez-Salinas, Manuel Sanchez-Cantu

Patent number: 7641787Abstract: Compositions for reduction of NOx generated during a catalytic cracking process, preferably, a fluid catalytic cracking process, are disclosed. The compositions comprise a fluid catalytic cracking catalyst composition, preferably containing a Y-type zeolite, and a particulate NOx composition containing particles of a zeolite having a pore size ranging from about 3 to about 7.2 Angstroms and a SiO2 to Al2O3 molar ratio of less than about 500. Preferably, the NOx reduction composition contains NOx reduction zeolite particles bound with an inorganic binder. In the alternative, the NOx reduction zeolite particles are incorporated into the cracking catalyst as an integral component of the catalyst. Compositions in accordance with the invention are very effective for the reduction of NOx emissions released from the regenerator of a fluid catalytic cracking unit operating under FCC process conditions without a substantial change in conversion or yield of cracked products.Type: GrantFiled: November 7, 2008Date of Patent: January 5, 2010Assignee: W.R.
