  • Patent number: 10384986
    Abstract: A process is presented for the production of light olefins. The process utilizes a SAPO-18 catalyst and is operated at an elevated pressure. The process generates higher concentrations of heavier olefins which can then be processed to generate light olefins. The processing of the heavier olefins can include metathesis reactions and olefin cracking processes.

  • Patent number: 10093593
    Abstract: A process is presented for generating light olefins with the methanol to olefins process from a combination of catalysts. The process controls the product distribution for ethylene, propylene and butylenes, to enable shifting of the product distribution. The process includes passing a second catalyst to a reactor while the process is on-going.

  • Patent number: 9688587
    Abstract: A process for the conversion of oxygenates to olefins is presented. The process utilizes a catalyst having a 2-dimensional morphology, and the catalyst is a pentasil zeolite. The process is an oxygenate to olefins conversion under typical temperatures and pressures, but provides for an increased propylene yield and a reduced ethylene yield.

  • Publication number: 20170166493
    Abstract: A process is presented for the conversion of oxygenates to olefins. The process utilizes a catalyst comprising a silicoaluminophosphate with an added basic metal oxide. The basic metal oxide modifies the selectivity to increase the yields of propylene and heavier olefins. The increase in heavier olefins are processed downstream to further increase propylene yields, and to generate a process stream comprising butylenes.

  • Patent number: 9643897
    Abstract: A process for oxygenate conversion using a family of crystalline aluminosilicate zeolites that is a layered pentasil zeolite with a silica or fluorine modified surface. These zeolites are represented by the empirical formula: Mmn+Rrp+Al1-xExSiyOz where M is an alkali, alkaline earth, or rare earth metal such as sodium or potassium, R can be a mixture of organoammonium cations and E is a framework element such as gallium, iron, boron, or indium. These zeolites are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out oxygenate conversion processes.
