A universal chemical processor (UCP) including a reactor vessel with a main chamber, comprises inlets for feedstock, a fluidizing medium and reactants. The UCP further includes a reactive X-ray chemical processor (RXCP) having a large area hollow cylindrical cold cathode in the main chamber, a grid positioned concentrically with respect to the cathode, and an anode positioned concentrically with respect to the cathode and grid. In operation, when activated, the cathode of the RXCP emits electrodes onto the anode, which then emits X-rays into a radiation zone within the main chamber capable of ionizing feedstock and reactants, inducing chemical reactions, and sterilizing and decomposing organic materials within the radiation zone, and wherein, a fluidized bed is supported in the main chamber when the fluidizing medium and feedstock are supplied. The RXCP and the fluidized bed portions can be operated separately or in conjunction to achieve unanticipated results.

A process (and a related system) for collecting samples of a polymerization catalyst or of a catalyst-containing polymer from an operation unit, having an upper end and a lower end, of a polymerization plant, including the steps of: a) extracting a prefixed amount of product from the lower end of the operation unit through a discharge valve; b) directing the product towards a filtering unit through an inlet valve; c) flushing an inert gas through the filtering unit; d) outgassing the filtering unit, through the outlet valve; and e) displacing the filtering unit, for collecting the sample.

The present invention is generally directed to a reactor for the production of low-carbon syngas from captured carbon dioxide and renewable hydrogen. The hydrogen is generated from water using an electrolyzer powered by renewable electricity or from any other method of low-carbon hydrogen production. The improved catalytic reactor is energy efficient and robust when operating at temperatures up to 1800 F. Carbon dioxide conversion efficiencies are greater than 75% with carbon monoxide selectivity of greater than 98%. The catalytic reactor is constructed of materials that are physically and chemically robust up to 1800 F. As a result, these materials are not reactive with the mixture of hydrogen and carbon dioxide or the carbon monoxide and steam products.

The present invention relates to a system, method, and use for the unloading of solid material particles used in a physical, chemical, and/or biological process in a tank and for the inertization of the tank.

The pump is configured to generate negative pressure in the receiving tank and in the tank, and the inert gas supply device is configured to insert inert gas into the tank and supply inert gas to at least one injector, to allow the displacement of solid material particles from the tank to the receiving tank.

Disclosed is a method for preparing ammonia gas through a reaction between an ammonium salt and a silicate. An aqueous solution of the ammonium salt in the form of atomized droplets is contacted with a silicate at a high temperature for a reaction to generate ammonia gas and a solid substance. The silicate can be solid particles, and forms a bed. The generated ammonia gas is collected, the solid substance is extracted, part of the same solid substance is mixed with a fresh silicate solid particle, and the mixture continuously reacts with the atomized droplets of the aqueous solution of the ammonium salt.

A reactor system includes a reactor vessel configured to contain a process fluid, and a sparger assembly that operably coupled to the reactor vessel and configured to supply a mixture of a gas and a recirculated process fluid to the reactor vessel. The sparger assembly includes a plurality of sparger chambers. Each sparger chamber includes a process fluid conduit fluidly coupled to a process fluid return of the reactor vessel via a process fluid inlet, wherein the process fluid inlet has a first block and bleed valve assembly. Each sparger chamber includes a sparger conduit fluidly coupled to the process fluid conduit and a sparger disposed within the sparger conduit and fluidly coupled to a gas source via a gas inlet. Each sparger chamber also includes a process fluid-gas mixture outlet that fluidly couples the sparger conduit to a sparger outlet of the reactor vessel.
