A particle separation system for a catalytic chemical reactor.

The invention relates to the chemical industry and can be used for processing methane and other volatile, liquid, solid fusible hydrocarbons when producing hydrogen, soot, and other flammable gases. The invention relates to a method for the pyrolytic decomposition of hydrocarbons, in which a pyrolysis reactor arranged in a space bounded by a lining is heated by flue gases generated by combusting a hydrogen-enriched mixture of air and gaseous hydrocarbons, while ensuring a maximum decrease in CO.sub.2 emissions into the atmosphere. The invention also relates to a unit for the pyrolytic decomposition of hydrocarbons. The technical result is a high degree of separation of hydrogen and carbon by fast high-temperature pyrolysis at atmospheric pressure without oxygen supply and without CO.sub.2 production.

A system for and method of regenerating a siloxane treatment vessel. At least one heat exchanger receives a flow of fluid from the siloxane treatment vessel, and discharges a cooled flow. A knockout tank receives the cooled flow, separates a condensed portion for disposal, and discharges the remainder. A heater raises a temperature of the remainder flow of fluid, and delivers a heated flow to the siloxane treatment vessel.

The present invention provides a multistage single reactor system for hydroprocessing and a process of carrying out multistage hydroprocessing in the said reactor assembly consisting of, a fixed bed solid catalyst system, a feed injection system enabling axial flow of hydrogen saturated hydrocarbon feed, a hydrogen dispensing system inside the reactor enabling minimum required hydrogen flow in cross-flow pattern, also using multitudes of integrated separation and withdrawal limbs for continuous staging. The innovative reactor disclosed in the present invention enables continuous separation and withdrawal of gaseous products along the reactor length by means of combined horizontal reactor orientation and vertical separation limbs provided at the top of the horizontally oriented reactor. The advantage of the reactor assembly includes effective heat sink of exothermic reactions and lower severity of operation due to removal of inhibitory gaseous products.

A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.

The invention relates to a device (D) for distributing a fluid, which is able to be arranged in a fixed catalytic bed (C.sub.1, C.sub.2) of a reactor (R), said device comprising conveying means for conveying said fluid, comprising a plurality of pipes each directly receiving a distinct share of said fluid, distribution means for distributing said fluid, means for generating a local pressure drop in said fluid, such that: the device comprises manifold means (2a) for collecting said fluid together, and providing the fluidic connection between the pipes of said fluid conveying means and said fluid distribution means, said means for generating a local pressure drop are added on to said conveying or distribution or manifold (2a) means.

A catalytic reactor comprises a floating particle catcher unit and a particle catching surface which extracts particles from the fluid flow stream above the catalyst bed whereby at least a part of the particles settles on the particle catching surface instead of clogging the catalyst bed.

A chemical reactor is implemented on a substrate and has an inlet for receiving a fluid and/or a gas; a filter element for reducing or preventing that materials cause a blockage in the fluid supplied and/or the gas supplied in a part of the chemical reactor located further away; and a part located further away for transporting and/or processing the fluid and/or the gas. The part located further away has a depth dlow smaller than the depth dhigh of the inlet. The filter element has a first duct part and a second duct part; the first duct part is positioned closer up against the inlet than the second duct part, the first duct part is deeper than the second duct part, the first duct part has a diverging width and is free from pillar structures, and the second duct part is filled with filter pillars.

A catalytic reactor comprises a particle separator the reactor internals by means which makes the fluid flow stream perform a radial outwards and upwards S-curve flow path, which enables the particles to be extracted and settle in a collection section with low flow activity and turbulence.
