  • Patent number: 8431761
    Abstract: A method for obtaining an olefin is disclosed, the method comprising subjecting a paraffin to dehydrogenation in the absence of oxygen and in the presence of a catalyst comprising a crystalline substrate, to obtain an olefin. The catalyst includes an inert stabilizing agent for maintaining the catalyst crystal structure. The catalyst may be regenerated by being subjected, in air, to a temperature between about 550° C. and about 750° C., for a period of time between about 15 minutes and about 4 hours.
    Type: Grant
    Filed: June 22, 2009
    Date of Patent: April 30, 2013

  • Patent number: 8324441
    Abstract: A process is presented for the production of light olefins from a paraffin stream comprising pentanes. The process includes a series of pentane cracking reactors where a process stream having pentane in the process stream passes through the reactors with the process stream heated between each pair of successive reactors, and where the process is operated at low pressures.
