摘要： Catalytic compositions and catalytic processes are provided. The catalytic compositions are produced by the process that comprises contacting an organonickel compound with a cyclicazacarbyl compound. Optionally, one or more catalytic promoters can be present in the catalytic compositions. Additionally, one or more olefins can be contacted with one or more of these catalytic compositions to form oligomerization products and/or polymerization products.

摘要： Metals contained in a hydrocarbon containing feed stream are removed by contacting the hydrocarbon containing feed stream under suitable demetallization conditions with hydrogen and a catalyst composition comprising zirconium phosphate, cobalt phosphate and iron phosphate. The life and activity of the catalyst composition may be increased by introducing a decomposable metal compound selected from the group consisting of the metals of Group V-B, Group VI-B, Group VII-B and Group VIII of the Periodic Table into the hydrocarbon containing feed stream prior to contacting the hydrocarbon containing feed stream with the catalyst composition.
