  • Publication number: 20230093632
    Abstract: Disclosed herein is a method for producing a solid catalyst component for olefin polymerization that is capable of reducing the amount of fine powder contained in the solid catalyst component for olefin polymerization. The method includes the step of reacting a magnesium compound and a titanium halide compound with each other so that a maximum heat release rate per mole of the magnesium compound is 18 W or less. Also disclosed herein is a method for producing a solid catalyst component for olefin polymerization that is capable of preventing a reduction in polymerization activity caused by application of heat to the solid catalyst component for olefin polymerization. The method includes the step of reacting a magnesium compound and a titanium halide compound with each other so that a total heat release value per mole of the titanium compound is 6 kJ to 90 kJ.

  • Patent number: 10280125
    Abstract: A process for selectively producing 1-butene comprises contacting at least one antifouling agent with at least one aluminum alkyl compound to form at least one antifouling compound in a first step. The antifouling compound may comprise a structure comprising a central aluminum molecule bound to an R1 group, bound to an R2 group, and bound to an R3 group. The process further comprises feeding the antifouling compound, an additional amount of the aluminum alkyl compound, at least one titanate compound, and ethylene into a reactor to dimerize ethylene in a second step. The titanate compound is fed as a stream separated from the streams of the antifouling compound and the additional amount of the aluminum alkyl compound. The molar ratio of the sum of the aluminum alkyl compound to the titanate compound is equal to or higher than 1.5 and equal to or lower than 3.0.

  • Patent number: 9497360
    Abstract: A small camera module is simply assembled in a short time, while reducing displacement of a camera relative to the first and second frames. Specifically, the camera module is assembled by bending a pair of clips to engage engaging portions of the clips with engaging recesses of the first and second frames to fix the first frame, camera holders, and the second frame, with the first and second frames located at both sides of each camera holder with a housing recess facing outward, and using resilient force of each of the clips to press the camera with a projection of the clip.
