  • Patent number: 9108906
    Abstract: A process for the production of olefin sulfonates is presented. The process comprising generating olefins from normal alkanes through a dehydrogenation unit to produce a mixture of alkanes and alkenes. The mixture is sulfonated to react the olefins and generate olefin sulfonates. The olefin sulfonates are separated from the normal alkanes to produce a product stream, with the normal alkanes recycled to the dehydrogenation unit.

  • Publication number: 20150126770
    Abstract: A process for increasing the production of monoalkylbenzenes is presented. The process includes utilizing a transalkylation process to convert dialkylbenzenes to monoalkylbenzenes. The feed to the transalkylation process has alkylated toluenes and alkylated ethylbenzenes and other alkylated aromatics having small alkyl groups with less than 8 carbons removed to improve the efficiency of the transalkylation process. The recycled dialkylbenzenes and a portion of the recycled benzene are converted to monoalkylbenzenes.

  • Publication number: 20150105599
    Abstract: Methods of removing free oxygen from a hydrocarbon stream are described. A hydrocarbon stream containing free oxygen is contacted with an adsorbent comprising a metal in a reduced state. The free oxygen in the hydrocarbon stream reacts with the metal in the reduced state to form oxidized metal and a reduced oxygen hydrocarbon stream. Syngas is made from a portion of the reduced oxygen hydrocarbon stream. A regeneration gas stream comprising a mixture of the syngas and another portion of the reduced oxygen hydrocarbon stream is contacted with the oxidized metal to reduce the oxidized metal to form the metal in the reduced state.
