  • Publication number: 20190300805
    Abstract: The present disclosure relates generally to systems operable to produce liquid transportation fuels by converting a hydrocarbon feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. The system separates the hydrocarbon feed stream to form a first fraction comprising isopentane and smaller hydrocarbons, and a second fraction comprising n-pentane and larger components of the hydrocarbon feeds stream. Each fraction is then catalytically-activated in a separate activation reactor containing a separate activation catalyst, where the conditions maintained in each reactor are selected to maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first activation reactor is maintained at a lower temperature than the second activation reactor.

  • Publication number: 20190300454
    Abstract: The present disclosure relates generally to processes and systems for producing liquid transportation fuels by converting a feed stream that comprises both isopentane and n-pentane, and optionally, some C6+ hydrocarbons. Isopentane and smaller hydrocarbons are separated to form a first fraction while n-pentane and larger components of the feed stock form a second fraction. Each fraction is then catalytically-activated in a separate reaction zone with a separate catalyst, where the conditions maintained in each zone maximize the conversion of each fraction to olefins and aromatics, while minimizing the production of C1-C4 light paraffins. In certain embodiments, the first fraction is activated at a lower temperature than the second fraction. The process provides increased yields of upgraded hydrocarbon products that possess the characteristics of a liquid transportation fuel or a blend component thereof.

  • Patent number: 10400182
    Abstract: The present disclosure relates generally processes and systems for converting a mixture of light hydrocarbons to liquid transportation fuels by first cracking the light hydrocarbons to an intermediate comprising olefins, which is converted by contacting with a catalyst comprising at least one zeolite in two separate conversion stages with an intervening recovery of liquid product. The first stage conversion favors oligomerization of larger olefins to form diesel range products that are collected prior to directing unconverted smaller olefins to be oligomerized in a second stage conversion conducted at a higher temperature and lower pressure.

  • Patent number: 10214462
    Abstract: A process for post synthesis treatment of ZSM-5 catalyst for converting ethylene to liquid fuel products providing substantially improved catalyst life. The treatment comprises either a base treatment, an acid treatment or a two-step treatment where one is with an acid and the other is with a base. The base treatment is provided by a weak sodium hydroxide such as less than 1 Molar concentration. The acid treatment is stronger acid where, for example, a hydrogen chloride solution at greater than 2 Molar concentration is used.

  • Patent number: 9452931
    Abstract: A process is described for flowing an oxygenate feed over a catalyst in an adiabatic fixed bed reactor to product a reactor effluent and heat. The reaction inside the adiabatic fixed bed reactor occurs at a reaction temperature from about 200° C. to about 375° C. The reactor effluent is then condensed to separate the liquid products and the gaseous products. A separation step then separates the gaseous products into hydrogen and off-gas.

  • Patent number: 9266755
    Abstract: Methods and apparatus relate to treating fluid to at least reduce selenium content within the fluid. The treating includes conditioning stages to alter a composition of the fluid prior to removal of the selenium content from the fluid. The composition of the fluid after the conditioning stages facilitates the removal of the selenium content or at least limits detrimental impact to selenium removal efficiency.
