    Abstract: Methods and systems for hydrocracking a heavy oil feedstock include using a colloidal or molecular catalyst (e.g., molybdenum sulfide) and provide for concentration of the colloidal or molecular catalyst within the lower quality materials requiring additional hydrocracking in one or more downstream reactors. In addition to increased catalyst concentration, the inventive systems and methods provide increased reactor throughput, increased reaction rate, and of course higher conversion of asphaltenes and lower quality materials. Increased conversion levels of asphaltenes and lower quality materials also reduces equipment fouling, enables the reactor to process a wider range of lower quality feedstocks, and can lead to more efficient use of a supported catalyst if used in combination with the colloidal or molecular catalyst.

  • Publication number: 20110240520
    Abstract: The production of light hydrocarbons consisting of ethylene, propylene, butylenes, and of gasoline is enhanced by introducing a virgin paraffinic naphtha feedstream derived from an external source into an ancillary downflow reactor that utilizes the same catalyst composition as an adjacent FCC unit for cracking the naphtha and withdrawing the desired lighter hydrocarbon reaction product stream from the downflow reactor and regenerating the catalyst in the same regeneration vessel that is used to regenerate the spent catalyst from the FCC unit. The efficiency of the recovery of the desired lighter olefinic hydrocarbons is maximized by limiting the feedstream to the downflow reactor to paraffinic naphtha that can be processed under relatively harsher conditions, while minimizing production of undesired by-products and reducing the formation of coke on the catalyst.

  • Patent number: 7638664
    Abstract: One exemplary embodiment can include a hydrocarbon conversion process. Generally, the process includes passing a hydrocarbon stream through a hydrocarbon conversion zone comprising a series of reaction zones. Typically, the hydrocarbon conversion zone includes a staggered-bypass reaction system having a first, second, third, and fourth reaction zones, which are staggered-bypass reaction zones, and a fifth reaction zone, which can be a non-staggered-bypass reaction zone, subsequent to the staggered-bypass reaction system.

  • Publication number: 20090229172
    Abstract: A process has been developed for producing a diesel boiling point range product and an aviation boiling point range product from renewable feedstocks such as plant and animal oils. The process involves treating a renewable feedstock by hydrogenating and deoxygenating to provide a hydrocarbon fraction which is then isomerized and selectively cracked to form the diesel boiling point range product and the aviation boiling point range product. A portion of the diesel boiling point range product, aviation boiling point range product, naphtha product, LPG, or any combination thereof can be optionally used as a rectification agent in the selective hot high pressure hydrogen stripper to decrease the amount of product carried in the stripper overhead.

  • Publication number: 20090050522
    Abstract: A process for supplementing steam reformation with hydrogen, oxygen and heat from dissociation of hydrogen peroxide (H2O2). Steam reforming suffers from starting the overall system in an endothermic manner which leads to long start times and limited turndown capability in delivering high quality hydrogen. Using a material such as hydrogen peroxide in a controlled manner allows for instant generation of oxygen-enriched steam, an essential state in reforming hydrocarbons. It additionally, offers the opportunity to relieve parasitic power requirements associated with compressing air to reach the O2 density required for the reforming process and eliminates, or minimizes (as a function of overall power system design requirements) post process cleanup of nitrogen-oxides.

  • Patent number: 7491315
    Abstract: A dual riser FCC process is disclosed wherein first and second hydrocarbon feeds (5, 6) are supplied to the respective first and second risers (2, 4) to make an effluent rich in ethylene, propylene and/or aromatics. Where the hydrocarbon feeds are different, the respective risers can have different conditions to favor conversion to ethylene and/or propylene. A minor amount of a coke precursor (80, 82) can be added to one or both of the hydrocarbon feeds (5, 6) to reduce or eliminate the amount of supplemental fuel needed to heat balance the system. The different feeds, including the coke precursor and any recycle streams (36, 44) can be segregated by type to improve olefin yields, including an embodiment where the paraffinic feeds are supplied to one riser and the olefinic feeds to the other.

  • Patent number: 7351324
    Abstract: The present invention relates to a liquid fuel blended by dissolving crude pentane into the heavy oil with different proportions, and applied to different combustion system respectively; the fuel thus formed is easily dissolved, volatilized, atomized and vaporized into fine vapor articles, so it will burn completely to not only increase the heat value but also reduce the pollution without producing the dense smoke like common heavy oil combustion furnace. In addition, alkanes with low price, low octane value and high volatility substitute or blend with the crude pentane to become a liquid fuel having suitable initial boiling point, viscosity and fluidity as well as low price and low pollution, which is much better than common diesel oil.

  • Patent number: 7318845
    Abstract: A distillate fuel steam reformer system in which a fuel feed stream is first separated into two process streams: an aliphatics-rich, sulfur-depleted gas stream, and an aromatics- and sulfur-rich liquid residue stream. The aliphatics-rich gas stream is desulfurized, mixed with steam, and converted in a reforming reactor to a hydrogen-rich product stream. The aromatics-rich residue stream is mixed with air and combusted to provide heat necessary for endothermic process operations. Reducing the amounts of sulfur and aromatic hydrocarbons directed to desulfurzation and reforming operations minimizes the size and weight of the overall apparatus. The process of the invention is well suited to the use of microchannel apparatuses for heat exchangers, reactors, and other system components, which may be assembled in slab configuration, further reducing system size and weight.

  • Patent number: 7311815
    Abstract: A method of preparing high linear paraffin or high end-chain monomethyl content products is accomplished by converting synthesis gas in a Fischer-Tropsch reaction to hydrocarbon products. These may be hydrotreated to provide an n-paraffin content of greater than 50% by weight, with substantially all branched paraffins being monomethyl end-chain branched paraffins. At least one non-linear paraffin isomer, which may be a monomethyl paraffin isomer, may be separated from the hydrocarbon products through distillation to provide an n-paraffin product having an n-paraffin content percentage by weight of the n-paraffin product that is greater than the initial n-paraffin content.

  • Patent number: 7303598
    Abstract: Apparatus and process for reformulating liquid fuel. In one step of the process the fuel is fractionated into light and heavy fractionates. The light fractionate is then reformed in a steam reformer into a reformed fuel that is suitable for use in fuel cells or other energy-producing devices. The heavy fractionate is burned with a part of the resulting heat used in the reforming step. In one embodiment the light fractionate is desulfurized before entering the reforming step. In another embodiment the heavy fractionate is directed into a holding vessel for subsequent use as a fuel which is suitable for burning to produce heat or other energy.
