Production Of Hydrocarbon Mixture From Refuse Or Vegetation Patents (Class 585/240)
  • Patent number: 10358605
    Abstract: The invention relates to a method to reduce the formation of high molecular weight compounds and catalyst coking in the production of renewable diesel. Renewable diesel is produced using hydrogenation, decarboxylation, decarbonylation, and/or hydrodeoxygenation of renewable feedstocks such as animal and/or plant fats, oils, and/or greases (FOG). By first reacting the most reactive species in the FOG in an initial reaction zone prior to the main reaction zone, maximum reaction temperatures and side reactions that lead to the formation of high molecular weight compounds are reduced. This reduces catalyst coking (extends catalyst life) and improves product quality.

  • Patent number: 10329494
    Abstract: The present disclosure relates to a system and a process for producing biofuel. The system comprises at least one feed tank; a low pressure pump; a high pressure pump; a first heat exchanger; a second heat exchanger; a reaction vessel; a precipitation vessel; a first pressure let-down station; a third heat exchanger; a second pressure let-down station; a gas-liquid separator; and a biofuel separator. The process comprises pressurizing and heating a feed, followed by reforming the pressurized and heated feed to obtain a slurry. The solids are separated from the slurry by precipitation to obtain a mixture comprising biofuel and the non-reformed feed. The mixture is then cooled and de-pressurized, followed by separation of gases and the non-reformed feed to obtain the biofuel. The system and process of the present disclosure can be used to produce biofuel from diverse, easily available and inexpensive starting material.

  • Patent number: 10272417
    Abstract: The invention relates to the preparation of novel bi- or tri metallic silicate micro-porous and/or meso-porous materials based on cerium, nickel, copper and/or zinc on a porous silicate framework matrix to use its molecular sieve effect to target preferentially the acidic organic molecules present in hydrocarbon feedstocks like crude oil, bitumen, VGO and the like. The chosen metals are selected based on their ability to activate steam and transfer oxygen for completing the oxidation of carboxylic compounds or decarboxylating them. These composite materials can be prepared under hydrothermal synthesis conditions in order to produce suitable porous solids where the metals are well dispersed and preferentially distributed inside the channels of the silicate framework where they can interact only with the molecules that can go inside the channels.

  • Patent number: 9617479
    Abstract: Feeds containing triglycerides are processed to produce a diesel fuel product and propylene. The diesel product and propylene are generated by deoxygenating the triglyceride-containing feed using processing conditions that enhance preservation of olefins that are present in the triglycerides. The triglyceride-containing feed is processed in the presence of a catalyst containing a Group VI metal and a Group VIII non-noble metal and in the presence of CO.

  • Patent number: 9611554
    Abstract: Oils from plants and animal fats are hydrolyzed to fatty acids for a Kolbe reaction. The invention relates to a high productivity Kolbe reaction process for electrochemically decarboxylating C4-C28 fatty acids derived from sources selected based on their saturated and unsaturated fatty acid content in order to lower anodic passivation voltage during synthesis of C6-C54 hydrocarbons. The C6-C54 hydrocarbons may undergo olefin metathesis and/or hydroisomerization reaction processes to synthesize heavy fuel oil, diesel fuel, kerosene fuel, lubricant base oil, and linear alpha olefin products useful as precursors for polymers, detergents, and other fine chemicals.

  • Patent number: 9523046
    Abstract: Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.

  • Patent number: 9522864
    Abstract: A method of catalytically preparing a fluid product from solid carbonaceous material is described. In the method, at least one of the following equilibria is established by one or more catalysts: a) CH3OH?CO+2H2, b) CO+H2O?CO2+H2. In some versions, the solid carbonaceous material is woody biomass. Components of the fluid product can include one or a combination of C5-C9 alcohols. In certain versions, the method can he practiced with substantially all of the carbon in the carbonaceous material being converted to the fluid product. Also, in some versions, the fluid product can be prepared with substantially no char formation. The fluid product of various versions can be used directly as fuel or as a reagent for preparing commodity chemicals without the need for separating the fluid product components.
