Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Abstract: A method for converting methanol to gasoline boiling range hydrocarbons is disclosed. In an aspect the method includes feeding crude methanol from a methanol synthesis reactor to a methanol separation vessel to recover a methanol stream in a vapor phase; and without condensing the methanol stream, feeding the methanol stream in the vapor phase to a reactor containing a conversion catalyst for converting methanol to at least one of dimethyl ether or gasoline boiling range hydrocarbons.

Abstract: In a process for upgrading paraffins and olefins, a first feed comprising C14− olefins is contacted with an oligomerization catalyst in a first reaction zone under conditions effective for oligomerization of olefins to higher molecular weight hydrocarbons. Deactivated catalyst is removed from the first reaction zone at a first temperature and is contacted with an oxygen-containing gas and a hydrocarbon-containing fuel in a regeneration zone to regenerate the catalyst and raise the temperature of the catalyst to a second, higher temperature. A second feed comprising C14− paraffins is contacted with the regenerated catalyst in a second reaction zone to convert at least some of the paraffins in the second feed to a reaction effluent comprising olefins, aromatic hydrocarbons and regenerated catalyst; and the reaction effluent is supplied to the first reaction zone. A system for performing such a process and a product of such a process are also provided.

Abstract: Systems and methods are provided for producing naphtha boiling range fractions having a reduced or minimized amount of sulfur and an increased and/or desirable octane rating and suitable for incorporation into a naphtha fuel product. A naphtha boiling range feed can be separated to form a lower boiling portion and a higher boiling portion. The lower boiling portion, containing a substantial amount of olefins, can be exposed to an acidic catalyst without the need for providing added hydrogen in the reaction environment. Additionally, during the exposure of the lower boiling portion to the acidic catalyst, a stream of light olefins (such as C2-C4 olefins) can be introduced into the reaction environment. Adding such light olefins can enhance the C5+ yield and/or improve the removal of sulfur from thiophene and methyl-thiophene compounds in the naphtha feed.

Abstract translation: 提供了用于生产具有减少或最小量的硫以及增加和/或期望的辛烷值并且适于掺入石脑油燃料产物中的石脑油沸程级分的系统和方法。 可以将石脑油沸程进料分离以形成较低沸点部分和较高沸点部分。 含有大量烯烃的低沸点部分可以暴露于酸性催化剂，而不需要在反应环境中提供添加的氢气。 此外，在低沸点部分暴露于酸性催化剂期间，可以将轻质烯烃（如C 2 -C 4烯烃）引入反应环境中。 加入这样的轻质烯烃可以提高石脑油进料中的C5 +产率和/或改善噻吩和甲基 - 噻吩化合物中硫的去除。
