Abstract: A process for producing isooctane by introducing a butane feed stream (containing n-butane, i-butane) and hydrogen into a catalytic hydrogenolysis reactor to produce a hydrogenolysis product stream; separating the hydrogenolysis product stream into a butane stream (i-butane, optionally n-butane); feeding the butane stream to a catalytic dehydrogenation reactor to produce a dehydrogenation product stream comprising saturated and unsaturated four-carbon hydrocarbons; and feeding the dehydrogenation product stream to an oligomerization unit to produce isooctene and dehydrogenating the isooctene to produce isooctane.

Abstract: A process for producing light alkanes and creating a flexible distribution system for those alkanes and related systems are disclosed. The process can include supplying a butane feed stream to a butane conversion unit to produce a light alkane output stream including at least methane, ethane, propane, and hydrogen, separating at least part of the light alkane output stream into separate streams of methane, ethane, and propane and distributing the separated streams as desired. The distribution of the separated streams can include sending the separated ethane and propane streams to downstream processing units which use them as feedstock. The butane containing feed and/or unreacted butane feed can include isobutane, which can be converted to n-butane and then further processed.

Abstract: A catalyst includes a zeolite, wherein the zeolite has: a CHA framework; a particle size less than or equal to 100 nanometers; and a silica to alumina mole ratio in the range of about 50:1 to about 150:1. The catalyst can include a metal dopant. The catalyst can be used for purifying a product by flowing a reactant across the catalyst to form the product; and condensing or separating the product. The product can be an olefin or alkenes with an increased carbon chain. The catalyst can be used for selective catalytic reduction of nitrogen oxide or a gas to liquid reaction. A method of producing the catalyst can include selecting the concentration of a crystal growth inhibitor based on the ratio of the silica precursor and an alumina precursor such that the zeolite crystals have a mean particle size less than or equal to 100 nanometers.

Abstract: A process for producing benzene comprising the steps of:(a) separating a source feedstream comprising C5-C12 hydrocarbons including benzene and alkylbenzenes into a first feedstream comprising a higher proportion of benzene than the source feedstream and a second feedstream comprising a lower proportion of benzene than the source feedstream and subsequently, (b) contacting the first feedstream in the presence of hydrogen with a first hydrocracking catalyst, and (c) contacting the second feedstream with hydrogen under second process conditions to produce a second product stream comprising benzene, wherein i) the second process conditions are suitable for hydrocracking and step (c) involves contacting the second feedstream in the presence of hydrogen with a second hydrocracking catalyst, ii) the second process conditions are suitable for toluene disproportionation and involve contacting the second feedstream with a toluene disproportionation catalyst or iii) the second process conditions are suitable for hydrodealkylation.

Abstract: Provided are systems and methods for obtaining ethylene and propylene products from, for example, shale gas and shale gas condensate feedstocks. These systems and method operate by utilizing a hydrocracker train to crack C4 and C5 hydrocarbons to a product stream of propane and ethane or using a hydrogenolysis train to process C4 and C5 hydrocarbons to a product stream of propane and ethane that is provided to a cracker for an efficient conversion to ethylene and propylene. The disclosed systems are configured to reduce the amount of offsite hydrogen needed and also provide product streams that include a well-defined set of products as compared to existing approaches.
