Patent number: 7754932Abstract: Processes, methods and apparatus relating to olefin oligomerization include the use of Raman spectrometry to monitor the concentration of reactants, products or other chemical components. One or more oligomerization conditions are adjusted in response to those monitored concentrations. The present processes, methods and apparatus are capable of monitoring olefin oligomerization with the use of low resolution Raman spectrometry equipment, even where there is some degree of overlap between Raman spectral peaks. Apparatus for olefin oligomerization reactions have at least one Raman probe located in the oligomerization equipment, the Raman probe providing an output signal, and Raman spectrometry equipment located outside the oligomerization equipment and operatively connected to at least one Raman probe.Type: GrantFiled: July 7, 2008Date of Patent: July 13, 2010Inventor: David R.

Patent number: 5362825Abstract: Pillared clay based high activity olefin polymerization catalysts, methods of producing the catalysts and methods of using the catalysts in the polymerization of olefins are provided. The methods of producing the catalysts each basically comprise contacting a pillared clay with the soluble complex produced by heating a mixture of a metal dihalide with a transition metal compound to produce a solid, and then reacting the solid with an organoaluminum halide. The process produces catalyst components shaped like dipyramidal or generally "football"-shaped crystals.Type: GrantFiled: July 13, 1992Date of Patent: November 8, 1994Assignee: Phillips Petroleum CompanyInventors: Gil R.
