  • Patent number: 11555154
    Abstract: The process removes hydrogen sulfide from hydrotreated gas by TSA. Hydrogen sulfide adsorbs on the adsorbent while allowing hydrogen in the hydrotreated gas to pass the adsorbent to provide a desulfided hydrogen gas stream and a sulfided adsorbent. A regenerant gas stream can be contacted with the sulfided adsorbent at a swing temperature to desorb hydrogen sulfide from the adsorbent into the regenerant gas stream. The regenerant gas stream can then be recycled to a hydrotreating reactor for processing biorenewable feed to provide hydrogen sulfide to the reactor. The desulfided gas stream can be purified to remove impurities such as carbon oxides and recycled to the hydrotreating reactor and/or used as the regenerant gas stream.

  • Patent number: 10960343
    Abstract: The present disclosure provides a method for generating higher hydrocarbon(s) from a stream comprising compounds with two or more carbon atoms (C2+), comprising introducing methane and an oxidant (e.g., O2) into an oxidative coupling of methane (OCM) reactor. The OCM reactor reacts the methane with the oxidant to generate a first product stream comprising the C2+ compounds. The first product stream can then be directed to a separations unit that recovers at least a portion of the C2+ compounds from the first product stream to yield a second product stream comprising the at least the portion of the C2+ compounds.

  • Publication number: 20150141719
    Abstract: A process to efficiently convert organic feedstock material into liquid non-oxygenated hydrocarbons in the C5 to C12 carbon skeleton range is disclosed. The process can utilize gaseous, liquid or solid organic feedstocks containing carbon, hydrogen and, optionally, oxygen. The feedstock may require preparation of the organic feedstock for the process and is converted first into a synthesis gas containing carbon monoxide and hydrogen. The synthesis gas is then cleaned and conditioned and extraneous components removed, leaving substantially only the carbon monoxide and hydrogen. It is then converted via a series of chemical reactions into the desired liquid hydrocarbons. The hydrocarbons are suitable for combustion in a vehicle engine and may be regarded a replacement for petrol made from fossil fuels in the C5 to C12 carbon backbone range.

  • Patent number: 8273930
    Abstract: A process for producing ethylene from ethanol combining the catalytic conversion of hydrocarbons: an ethanol feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, and a coked catalyst and an target product of ethylene are obtained after separating the reaction stream; a hydrocarbon feedstock is contacted with a Y-zeolite containing catalyst to give a product stream, a spent catalyst and an oil vapor are obtained after separating the reaction stream, and the oil vapor is further separated to give the products such as gas, gasoline and the like; a part or all of the coked catalyst and a part or all of the spent catalyst enter the regenerator for the coke-burning regeneration, and the regenerated catalyst is divided into two portions, wherein one portion returns to be contacted with the hydrocarbon feedstock, and the other portion, after cooling, returns to be contacted with ethanol feedstock.

  • Publication number: 20120172643
    Abstract: A process and system for separating and upgrading bio-oil into renewable fuels is provided. The process comprises separating bio-oil into a light fraction, an optional intermediate fraction, and heavy fraction based on their boiling points. The light fraction and optional intermediate fraction can be upgraded via hydrotreatment to produce a renewable gasoline and a renewable diesel, which may be combined with their petroleum-derived counterparts. The heavy fraction may be subjected to cracking and further separated into light, intermediate, and heavy fractions in order to increase the yield of renewable gasoline and renewable diesel.

  • Publication number: 20120136187
    Abstract: One exemplary embodiment can be a fluid catalytic cracking unit. The fluid catalytic cracking unit can include a first riser, a second riser, and a disengagement zone. The first riser can be adapted to receive a first feed terminating at a first reaction vessel having a first volume. The second riser may be adapted to receive a second feed terminating at a second reaction vessel having a second volume. Generally, the first volume is greater than the second volume. What is more, the disengagement zone can be for receiving a first mixture including at least one catalyst and one or more products from the first reaction vessel, and a second mixture including at least one catalyst and one or more products from the second reaction vessel. Typically, the first mixture is isolated from the second mixture.

  • Publication number: 20100292519
    Abstract: Byproduct formation in aromatic alkylation processes is reduced when different polyalkylated aromatic compounds are first fractionated into separate streams enriched in these respective polyalkylated aromatic compounds, and the separate streams are sent to different transalkylation reaction zones, which may or may not be in the same reactor. The different transalkylation reaction zones allow for greater control of the transalkylation of the respective polyalkylated aromatic compounds, such as diisopropylbenzene (DIPB) and triisopropylbenzene (TIPB) that accompany the alkylation of benzene with propylene in a process for cumene production.
