Abstract: Methanol-to-gasoline conversion may be performed using a heavy gasoline treatment, followed by a separation operation. Methanol may be converted into a first product mixture comprising dimethyl ether (DME) under DME formation conditions. In a methanol-to-gasoline (MTG) reactor, the first product mixture may be converted under MTG conversion conditions to produce a second product mixture comprising light gasoline hydrocarbons and untreated heavy gasoline hydrocarbons. The untreated heavy gasoline hydrocarbons may be separated from the light gasoline hydrocarbons and transferred to a heavy gasoline treatment (HGT) reactor. The untreated heavy gasoline hydrocarbons may be catalytically reacted in the HGT reactor to form a third product mixture. A heavy hydrocarbon fraction may be separated from the third product mixture. The heavy hydrocarbon fraction includes heavy gasoline hydrocarbons having a lower boiling endpoint than does the untreated heavy gasoline hydrocarbons.

Abstract: A method of producing a acid/metal bifunctional catalyst may include: mixing an acid catalyst, a metal catalyst, and a fluid to produce a slurry, wherein the acid catalyst is present at 50 wt % or less relative to a total catalyst weight in the slurry; heating the slurry; producing a powder from the slurry; and calcining the powder to produce the acid/metal bifunctional catalyst. Such acid/metal bifunctional catalyst would be useful in the direct conversion of syngas to dimethyl ether as well as other reactions.

Abstract: Systems and methods are provided for determining an asphaltene solubility distribution for a petroleum sample and/or other hydrocarbon sample. A vessel for performing the method can include both packing material(s) and sidewall(s) that correspond to substantially inert materials. The vessel can initially contain a precipitating solvent suitable for causing precipitation of asphaltenes from a hydrocarbon sample. Examples of a precipitating solvents can correspond to n-heptane, toluene, and mixtures of n-heptane and toluene. The petroleum sample is then introduced into the vessel, along with a carrier solvent. The volume of the precipitating solvent can be large relative to the sample, so that the solubility of asphaltenes in the sample becomes dependent on the properties of the precipitating solvent. If asphaltenes are precipitated, the asphaltenes can be washed out of the column using a dissolution solvent. The asphaltenes washed out using the dissolution solvent can then be characterized to determine a total asphaltene content.

Abstract: Provided are novel process for upgrading naphtha and increasing the yield of reformate. Olefinic naphtha and light paraffins are combined and fed to a catalytic fluidized bed reactor maintained at a temperature about 775° F. and about 1250° F. and an operating pressure between about 10 psig and about 500 psig to produce a product comprising at least 1 wt. % higher C5+ hydrocarbon than the combined feed and at least 55 wt. % aromatics.

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+).
