CATALYST AND PROCESS OF UPGRADING HEAVY OIL IN THE PRESENCE OF STEAM
Embodiments of the disclosure provide an aqueous reforming system and a method for upgrading heavy hydrocarbons. A hydrocarbon feed and a surfactant stream are combined to produce a first precursor stream. The first precursor stream and an alkali feed are combined to produce a second precursor stream. The second precursor stream and a transition metal feed are combined to produce a catalytic emulsion stream. The catalytic emulsion stream is heated to produce a catalytic suspension and a decomposition gas, where the decomposition gas is separated by a first separator. The catalytic suspension is combined with a preheated water stream to produce an aqueous reformer feed. The aqueous reformer feed is introduced to an aqueous reformer such that the heavy hydrocarbons undergo conversion reactions to produce an effluent stream. The effluent stream is introduced to a second separator to produce a heavy stream and a light stream. The light stream is introduced to a third separator to produce a gas stream, a distillate stream, and a spent water stream. Optionally, a portion of the distillate stream and the hydrocarbon feed can be combined to produce the first precursor stream such that the first precursor stream is in the absence of a surfactant.
SYSTEMS AND PROCESSES FOR DIRECT CONVERTING DISTILLATE FRACTIONS OF CRUDE OIL TO OLEFINS
A process for converting a hydrocarbon feed to olefins includes passing the hydrocarbon feed to a distillation system to separate the hydrocarbon feed to produce a light gas stream, a plurality of distillate fractions, and a residue. The process further includes passing at least one of the distillate fractions to a steam catalytic cracking system that includes at least one steam catalytic cracking reactor that is a fixed bed reactor containing a nano-zeolite cracking catalyst. The steam catalytic cracking system contacts the one or more of the plurality of distillate fractions with steam in the presence of the nano-zeolite cracking catalyst, which causes steam catalytic cracking of at least a portion of hydrocarbons in the at least one distillate fraction to produce a steam catalytic cracking effluent comprising the olefins.
CONVERSION OF PLASTICS TO MONOMERS WITH INTEGRATED RECOVERY WITH A CRACKING UNIT
A plastic pyrolysis process produces light olefin product and heavier products. The light olefin products are separated in a recovery process while the heavier product can be sent to a cracking unit to be further cracked to desired products. The cracked effluent stream may be subjected to the recovery process along with the light olefin product.

METHOD AND APPARATUS FOR MANUFACTURING STEEL USING ROTARY GENERATED THERMAL ENERGY
A method is provided for inputting thermal energy into fluidic medium in a steel manufacturing process by at least one rotary apparatus comprising: a casing with at least one inlet and at least one exit, a rotor comprising at least one row of rotor blades arranged over a circumference of a rotor hub mounted onto a rotor shaft, and a stator configured as an assembly of stationary vanes arranged at least upstream of the at least one row of rotor blades. In the method, an amount of thermal energy is imparted to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the exit by virtue of a series of energy transformations occurring when said stream of fluidic medium passes through the stationary vanes and the at least one row of rotor blades, respectively. The method further comprises: integration of said at least one rotary apparatus into a steel production facility configured to carry out steel production processes, such as reacting iron oxide and carbon or production of raw materials, at temperatures essentially equal to or exceeding 500 degrees Celsius (° C.), and conducting an amount of input energy into the at least one rotary apparatus integrated into the heat-consuming process facility, the input energy comprises electrical energy. A rotary apparatus and related uses are further provided.
Impregnated hierarchical mesoporous ZSM-5 zeolite catalysts for steam enhanced catalytic cracking of crude oil to petrochemicals
A process for upgrading crude oil through steam enhanced catalytic cracking includes contacting crude oil with steam and a cracking catalyst at a mass ratio of steam to crude oil of 0.2-1. The cracking catalyst is a hierarchical mesoporous ZSM-5 zeolite impregnated with phosphorous, cerium, lanthanum, and iron. Contacting the crude oil with steam and the cracking catalyst cracks a portion of the crude oil to produce light olefins, light aromatic compounds, or both. The cracking catalyst is prepared by partially disintegrating a starting ZSM-5 zeolite in a first mixture comprising sodium hydroxide and a surfactant and, after the disintegrating, recrystallizing zeolite constituents in the presence of the surfactant to produce a recrystallized ZSM-5 zeolite having a hierarchical pore structure. The recrystallized ZSM-5 zeolite is recovered and calcined to produce the hierarchical mesoporous ZSM-5 zeolite, which is then impregnated with the phosphorous, lanthanum, cerium, and iron.
