Abstract: Systems and methods for molten media pyrolysis for the conversion of methane into hydrogen and carbon-containing particles are disclosed. The systems and methods include the introduction of seed particles into the molten media to facilitate the growth of larger, more manageable carbon-containing particles. Additionally or alternatively, the systems and methods can include increasing the residence time of carbon-containing particles within the molten media to facilitate the growth of larger carbon-containing particles.

Abstract: Catalyst systems are provided, along with corresponding methods, for single stage conversion of synthesis gas to fuel boiling range products with increased selectivity for either naphtha production (C5-C9) or distillate production (C10-C20). The increased selectivity for naphtha production or distillate production is provided in conjunction with a reduced selectivity for higher boiling range components (C21+).

Abstract: A method for producing an isoolefinic stream may include: oligomerizing an ethylene stream to a C4+ olefin stream in a first olefin oligomerization unit comprising a serial reactor and a lights removal column, wherein the C4+ olefin stream contains no greater than 10 wt % of methane, ethylene, and ethane combined; and wherein the ethylene stream contains at least 50 wt % ethylene, at least 2000 wppm ethane, no greater than 1000 wppm of methane, and no greater than 20 wppm each of carbon monoxide and hydrogen; and oligomerizing the C4+ olefin stream and a propylene/C4+ olefin stream in a second oligomerization unit to produce the isoolefinic stream.

Abstract: Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of flexicoke material. Such proppant particulates may have improved transport into fractures because of lower density than traditional proppants like sand and may produce fewer fines that reduce fluid flow through proppant packs.

Abstract: Systems and methods are provided for partial upgrading of heavy hydrocarbon feeds to meet transport specifications, such as pipeline transport specifications. The systems and methods can allow for one or more types of improvement in heavy hydrocarbon processing prior to transport. In some aspects, the systems and methods can produce a partially upgraded heavy hydrocarbon product that satisfies one or more transport specifications while incorporating an increased amount of vacuum gas oil and a reduced amount of pitch into the partially upgraded heavy hydrocarbon product. In other aspects, the systems and methods can allow for increased incorporation of hydrocarbons into the fraction upgraded for transport, thereby reducing or minimizing the amount of hydrocarbons requiring an alternative method of disposal or transport. In still other aspects, the systems and methods can allow for reduced incorporation of external streams into the final product for transport while still satisfying one or more target properties.

Abstract: Systems and methods are provided for production of base stocks with a viscosity index of at least 120 and/or a sulfur content of 300 wppm or less and/or a kinematic viscosity at 100° C. of 3.0 cSt to 8.0 cSt by hydroconversion of a raffinate from aromatic extraction of a feed. The base stocks can further have a reduced content of 3+ ring naphthenes, such as 4.0 wt % or less, or 1.0 wt % or less. The base stocks can be produced by performing an elevated amount of feed conversion relative to 370° C. during hydroconversion of the raffinate, and optionally additional conversion during catalytic dewaxing of the hydroconverted raffinate. The base stocks can optionally be blended with additional base stocks and/or lubricant additives for production of lubricant compositions.
