METHOD AND REACTOR FOR CONVERSION OF HYDROCARBONS Russian patent published in 2021 - IPC B01J19/00 B01J19/24 C07C2/58 

FIELD: hydrocarbons conversion.

SUBSTANCE: invention relates to conversion processes for converting a wide range of hydrocarbons to produce more valuable products, and reactor designs for such conversion. A reactor system for converting hydrocarbons, including: a reactor vessel having a reactor wall that defines a reaction chamber; a reactor inlet assembly having a converging channel including a circumferential wall that encloses a central longitudinal axis and extends from opposite ends of the converging channel located upstream and downstream, the circumferential wall narrows in width from the ends located downstream and upstream, to an annular constrained thinned part located between the ends of the converging channel located downstream and upstream, and the end of the converging channel located downstream, is in fluid communication with the reaction chamber of the reactor, with the end of the converging channel located upstream of the process stream forming an inlet of the reactor inlet assembly; feed collection unit in fluid communication with the inlet of the reactor inlet collection unit, the central axis extending through the feed collection unit, the supply material collection unit comprising: a downstream wall of the feed collection unit that extends circumferentially around the disposed the upstream end of the reactor inlet assembly and connects to this end, the downstream wall of the feed material collection unit is oriented perpendicularly or substantially perpendicularly with respect to the central axis; an upstream wall of the feed collection assembly that is axially spaced upstream above the downstream wall of the feed collection assembly along a central axis and extends perpendicularly or substantially perpendicularly across the central axis; an upstream gas dividing wall and a downstream gas dividing wall, each of which is axially spaced between the downstream and upstream walls of the feed collection unit and which are axially spaced from one another, with an upstream the downstream gas dividing wall and the downstream gas dividing wall or circumferential portions thereof are oriented perpendicular or substantially perpendicular to the central axis, at least one wall, selected from an upstream gas dividing wall and a downstream gas dividing wall, terminates at a position upstream of the converging channel, which defines a central opening that encloses the central axis of the converging channel, wherein between the upstream wall of the feed collection unit and the upstream dividing wall, an upstream annular inlet flow space is defined, a downstream inlet flow annular space is defined between the downstream wall of the feed collection unit and the downstream gas dividing wall, an intermediate space is defined between the upstream gas dividing wall and the downstream gas dividing wall intake current; where said annular inlet flow spaces cause the introduced feed materials to flow perpendicular or substantially perpendicular to the central axis of the converging channel in the form of an inward swirling fluid flow pattern within said flow spaces around the central axis of the converging channel; and where the region extending from the central opening of at least one wall selected from the upstream and downstream dividing walls to the inlet of the reactor inlet assembly defines the central chamber of the feed collection, with heated combustion gases from at least one of the spaces of the inlet flow is led out into the central chamber, wherein the feed hydrocarbon material and the heated combustion gases pass in the form of swirling gases through the converging channel into the reaction chamber.

EFFECT: increasing the efficiency of conversion of hydrocarbons.
