Patent number: 6632772Abstract: A method of coating a catalyst to a support for use in acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in a liquid to form a suspension of particles of the catalyst. The precipitation of the catalyst particles is controlled by homogenizing the catalyst particles suspended in the liquid. The phase separation between the catalyst particles and the liquid can be substantially slowed down by the homogenization. Then the catalyst is coated on an inert support by applying the suspension of the catalyst particles to the support. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of the liquid required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating the liquid from the suspension.Type: GrantFiled: December 22, 2000Date of Patent: October 14, 2003Assignee: LG Chemical, Ltd.Inventors: Won-Ho Lee, Kyung-Hwa Kang, Dong-Hyun Ko, Young-Chang Byun

The support comprises fluorided alumina. The support has a surface area from about 200 to about 550 square meters per gram and a pore volume from about 0.7 to about 2.5 cubic centimeters per gram. The first component is activated at a temperature in the range of about 500° C. to about 900° C. The second component is a transition metal halide catalyst. A process comprising polymerizing ethylene or copolymerizing ethylene and at least one other monomer using the catalyst system to produce ethylene polymers is also provided.Type: GrantFiled: December 30, 1998Date of Patent: December 17, 2002Assignee: Phillips Petroleum CompanyInventors: Max P. McDaniel, Elizabeth A. Benham, Al R. Wolfe

Publication number: 20020165085Abstract: A solid catalyst component comprises a transition metal-containing metallocene compound, a non-cyclopentadienyl transition metal compound, a magnesium compound and a polymeric material which acts as a support. The catalyst component is combined with co-catalyst organoaluminum compound or a mixture of organoaluminum compounds to provide a catalyst composition useful for olefin polymerization, e.g., to produce linear low, medium and high density polyethylenes or copolymerization of ethylene with alpha-olefins. Product polyolefin polymers have a varied range of molecular weight distributions.Type: ApplicationFiled: January 18, 2002Publication date: November 7, 2002Applicant: Saudi Basic Industries CorporationInventors: Orass Hamed, Akhlaq Moman, Atieh Abu-Raqabah

Publication number: 20020156206Abstract: A make-up catalyst of at least one metallic component of a bimetallic catalyst component is used in conjunction with a bimetallic catalyst to control the proportion of weight fractions in broad or bimodal molecular weight distribution olefin resin product. The bimetallic catalyst produces broad or bimodal molecular weight distribution polyolefin resin whose composition depends on the ratio of the concentration of the two catalyst components producing the HMW/LMW components. The make-up catalyst consisting of a single metal component is added in proportion necessary to make-up the deficiencies in the amount of the HMW/LMW component. The type of make-up catalyst added depends on whether increase of the HMW or LMW component produced by te bimetallic catalyst is sought.Type: ApplicationFiled: April 15, 2002Publication date: October 24, 2002Inventors: Thomas E. Nowlin, Sandra D. Schregenberger, Pradeep P. Shirodkar, Grace O. Tsien
