Abstract: CO2 emissions from Fischer-Tropsch facilities are controlled by using multiple reactors. A process for the conversion of syngas using multiple Fischer-Tropsch reactors comprises reacting at least a portion of a first syngas in a first Fischer-Tropsch reactor to form a first hydrocarbonaceous product and a second syngas. The second syngas is mixed with a H2-containing stream to form an adjusted syngas. At least a portion of the adjusted syngas is reacted in a second Fischer-Tropsch reactor to form a second hydrocarbonaceous product and a third syngas. At least a portion of the first and second hydrocarbonaceous products are blended to obtain a blended hydrocarbonaceous product.

Abstract: CO2 emissions from Gas-to-Liquids (GTL) facilities such as, for example, Fischer-Tropsch facilities, are minimized by using recovered hydrogen as a fuel in at least one furnace in the GTL facility. A process for manufacturing hydrocarbonaceous products from a methane-containing feedstock in a GTL facility comprising at least one furnace generating reduced CO2 emissions comprises forming syngas from a methane-containing feedstock by means of a partial oxidation reaction. A hydrogen rich fuel is used in at least one furnace in the GTL facility to reduce CO2 emissions generated by the facility.

Abstract: CO2 emissions from syngas conversion processes are reduced by use of a multi-stage Fischer-Tropsch reaction system. A process for the conversion of syngas using a Fischer-Tropsch reactor comprises forming a first syngas and reacting at least a portion of the first syngas in a Fischer-Tropsch reactor to form a first hydrocarbonaceous product and a second syngas. The second syngas is mixed with a hydrogen-containing stream to provide an adjusted syngas, at least a portion of which is reacted in a dual functional syngas conversion reactor to form a second hydrocarbonaceous product and a third syngas comprising a reduced amount of CO2 than was present in the adjusted syngas.

Abstract: Provided is a process for converting CO2-rich natural gas into liquid fuel. The process includes introducing a CO2-rich natural gas feed stream into a synthesis gas formation reactor and then forming a synthesis gas. At least a portion of the synthesis gas is then introduced into a Fischer-Tropsch reactor. A Fischer-Tropsch process is conducted generating a Fischer-Tropsch product. A naphtha is separated from the Fischer-Tropsch product and introduced into a naphtha reformer. Hydrogen by-product is generated by reforming the naphtha to obtain a C6-C10 product having a hydrogen to carbon ratio less than about 2.0. At least a portion of the hydrogen by-product is recirculated and mixed with the CO2-rich natural gas feed stream.

Abstract: Olefins and alcohols present in Fischer-Tropsch light naphthas are converted to dialkyl ethers of the formula: R—O—R? where R and R? are each primarily non-tertiary alkyl groups of more than four carbon atoms, via hydration of the olefins to alcohols followed by dehydration of the alcohols. Ethers may also form by direct reaction of olefins and alcohols. The ethers are separated from the remaining paraffins in the naphtha by distillation and added in an amount of 1-25 wt. % to paraffinic mid-distillate fuel components obtained by hydrotreating a Fischer-Tropsch product. The properties of the distillate fuel components such as lubricity and seal swell are improved by the dialkyl ethers. The removal of olefins and alcohols from the naphthas reduces refining and lead to a more salable product.

Abstract: Provided is a process for converting methane at a remote natural gas site into ethylene and other products. Methane is converted into syngas which is converted into a low-sulfur liquid hydrocarbon mixture containing less than 1 ppm sulfur via Fischer-Tropsch (FT) syntheses. The low-sulfur Fischer-Tropsch liquids are transferred from the remote site to an existing facility where a sulfur-containing compound or a sulfur-containing hydrocarbon mixture is added to avoid coking problems. The resultant blend of hydrocarbons which has a sulfur content of at least 1 ppm, is fed to a naphtha cracking unit and ethylene recovered.

Abstract: A process for preparing hydrocarbons in the lube base oil range, lube base oils and lube oil compositions from a fraction with an average molecular weight above a target molecular weight and a fraction with an average molecular weight below a target molecular weight via molecular averaging is described. The fractions can be obtained, for example, from Fischer-Tropsch reactions, and/or obtained from the distillation of crude oil. Molecular averaging converts the fractions to a product with a desired molecular weight, for use in preparing a lube oil composition. The product can optionally be isomerized to lower the pour point, and also can be blended with suitable additives for use as a lube oil composition.
