The present disclosure relates generally to a carbon-neutral process for the generation of carbon-neutral hydrogen and carbon-neutral electricity. More specifically, the present disclosure relates to compositions, methods and apparatus employing a carbon-neutral process for generating electricity employing a liquid organic hydrogen carrier (LOHC) for supplying hydrogen for generating the carbon neutral electricity. The present disclosure also relates more specifically to carbon-neutral compositions consisting of liquid organic hydrogen carriers used for supplying hydrogen to generate electricity that may be regenerated in a carbon-neutral process using an apparatus with a net zero atmospheric emission of carbon oxides.

Carbon-neutral process for generating electricity

Catalytic methods for synthesis of super linear alkenyl arenes and alkyl arenes are provided. The methods are capable of synthesizing super linear alkyl and alkenyl arenes from simple arene and olefin starting materials and with high selectivity for linear coupling. Methods are also provided for making a 2,6-dimethylnapthalene (DMN) or 2,6-methylethylnapthalene (MEN).

Catalytic synthesis of super linear alkenyl arenes using rhodium catalysts

Described herein are methods useful for preparing alkylaromatics.

Preparation of alkylaromatic compounds

A crude oil which contains at least 0.1 wt % unstable sulfur compounds is treated in a reaction zone at low temperature to convert at least 50 wt % of the unstable sulfur compounds contained therein. The reaction and removal of sulfur from the crude may be facilitated by contacting the crude oil with a catalytic material in the presence of a stripping fluid.

Removing unstable sulfur compounds from crude oil

The invention provides methods and compositions useful for synthesizing alkylaromatics from an n-alkanes.

Aromatization or dehydrocyclization of N-alkanes using soluble transition metal complexes

Provided is a process for preparing oligomers from an alkane. The process comprises (a) contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst such as an iridium catalyst complex comprising iridium complexed with a benzimidiazolyl-containing ligand to form olefins, and (b) contacting the olefins prepared in step (a) under oligomerization conditions with an oligomerization catalyst such as a nickel, platinum or palladium metal catalyst complex comprising the metal complexed with a nitrogen containing bi- or tridentate ligand to prepare oligomers of the olefins, and hydrogenating the olefin oligomers. In one embodiment, the ligands of the catalyst complexes in step (a) and step (b) can be the same.

Process for alkane oligomerization

The present invention discloses processes for generating a hydrocarbon feedstock for biofuels synthesis from lignin via hydroprocessing. Embodiments of the present invention can occur in a refinery setting or in a paper mill setting. Embodiments of the present invention can utilize the separated lignin or the entire black liquor solution.

Process for generating a hydrocarbon feedstock lignin

Provided is a process for preparing alkyl aromatic compounds. The process comprises contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst, e.g., a pincer iridium catalyst, to form olefins, and then contacting the olefins generated with an aromatic compound under alkylation conditions. Both reactions are conducted in a single reactor, and occur simultaneously.

Process for generating a hydrocarbon feedstock from lignin

The present invention is generally directed to methods and systems for processing biomass into usable products, wherein such methods and systems involve an integration into conventional refineries and/or conventional refinery processes. Such methods and systems provide for an enhanced ability to utilize biofuels efficiently, and they can, at least in some embodiments, be used in hybrid refineries alongside conventional refinery processes.

Hybrid refinery for co-processing biomass with conventional refinery streams

The present invention is generally directed to methods for processing lignin-containing biomass so as to render it more amenable to hydroprocessing, wherein such processing typically reduces the level of oxygen in the biomass. Following such processing, the resulting reduced-oxygen lignin-derived product can be hydroprocessed into a biofuel suitable for use as a transportation fuel. Additionally, in some embodiments, such methods can be integrated with one or more other processes, wherein such other processes can be production and/or logistical in nature.

Lignin upgrading for hydroprocessing to biofuel

A method is disclosed for converting syngas to Fischer-Tropsch (F-T) hydrocarbon products. A synthesis gas including carbon monoxide and hydrogen gas is provided to a F-T reactor. Also, acetylene is supplied to the F-T reactor. The ratio of the volume of acetylene to the volume of synthesis gas is at least 0.01. The synthesis gas and acetylene are reacted under suitable reaction conditions and in the presence of a catalyst to produce F-T hydrocarbon products. The F-T hydrocarbon products are then recovered from the reactor. The synthesis gas and acetylene may be provided in a combined feed stream or introduced separately into the reactor. The acetylene enhanced syngas conversion in a F-T reactor results in the synthesis of F-T products which have a tighter distribution of intermediate length carbon products than do F-T products synthesized according to conventional methods.
