Abstract:
The present disclosure relates to reactor components and their use, e.g., in regenerative reactors. A process and apparatus for utilizing different wetted areas along the flow path of a fluid in a pyrolysis reactor, e.g., a thermally regenerating reactor, such as a regenerative, reverse-flow reactor, is described.
Abstract:
Herein disclosed is a reactor comprising a housing; an inlet tube having a section with perforations along its length, wherein the inlet tube section is within the reactor housing; an outlet tube having a section with perforations along its length, wherein the outlet tube section is within the reactor housing; and at least one cylinder made of sintered metal contained within the reactor housing, wherein the sintered metal is catalytically active. In some cases, the sintered metal in the reactor comprises a porous metallic multifunctional (PMM) catalyst. Other reactor designs and the method of use are also described herein.
Abstract:
Provided is a reformate hydrotreatment method, the method comprising: under liquid phase hydrotreatment conditions, bringing the reformate and a catalyst having a catalytic hydrogenation effect into contact in a hydrogenation reactor, the hydrogen used in the hydrotreating process at least partially coming from the hydrogen dissolved in the reformate. According to the method of the present invention, the reformate separated from a reformate products separating tank can directly undergo liquid phase hydrotreatment; therefore not only can the hydrogen dissolved in the reformate be fully utilized, but the olefins in the reformate can also be removed, while eliminate the requirements for recycle hydrogen and a recycle device thereof. The reformate obtained by the method of the present invention reduces the bromine index to below 50 mgBr2/100 g, and has an arene loss of less than 0.5 wt %.

The present application provides a scrubber for a gasification system. The scrubber may include a column, an inlet for a flow of dirty syngas, an inlet diffuser system positioned about the inlet, and an outlet for a flow of cleaned syngas.
Abstract:
An apparatus, system, and method are disclosed for capturing electrical energy from a process designed for producing hydrogen. An electrode is placed within a stream of liquid alkali metal that flows through a titration module and interacts with water to produce, among other byproducts, hydrogen. Another electrode is placed within a reaction chamber that houses the water. The electrodes can then be coupled to a terminal, and during the hydrogen generation process (when the liquid alkali metal and water interact) the stream of liquid alkali metal acts as an anode and the electrode in the water as a cathode. Current flows, and energy is captured and made available as electrical energy at the terminal, which can be connected to electrical loads. The terminal may be connected with the terminal of a fuel cell that is consuming the hydrogen that is being produced, thus providing additional voltage and/or current.
Abstract:
Device for distributing a fluid in a controlled manner, in particular for distributing a gas loaded with particles, the device comprising a pipe (1) provided with at least one inlet orifice (2) and with a series of outlet orifices (3) spread along the pipe (1) and cut in the side wall of this pipe, characterized in that at least one section (4) of the wall, located downstream of at least one outlet orifice and limited by a section (5) of the edge of this orifice, has a shape such that this section of the edge of this orifice is positioned inside the pipe so that, when the device is in service, the flow direction of the fluid exiting this orifice and travelling along said wall section is controlled by the shape of the latter section.

Abstract:
A reactor for the autorefrigerant alkylation process has a reactor vessel with a lower end inlet for the refrigerant reactant and the sulfuric acid and a series of inlets for the olefin reactant at vertically spaced intervals. A flow path for the reactants is provided by co-acting baffles which define sequential reaction zones. The baffles interact with a rotary mixer with multiple impellers to provide agitation. Outlets for the vaporized refrigerant and the reaction effluent are provided at the upper end of the vessel. In the alkylation process, the liquid isoparaffin hydrocarbon reactant/refrigerant with a sulfuric acid alkylation catalyst is introduced into the lower end and passed along the extended reactant flow path with the olefin reactant introduced at intervals along the path. The reaction mixture flows in the sequence of serial reaction zones within the reactor to promote mixing of the isoparaffin reactant with the acid catalyst.
Abstract:
Methods and apparatus for introducing a gas into the reaction zone of a reactor. Such methods and apparatus can more evenly distribute the gas throughout the reaction zone. Spargers for introducing a gas into the reaction zone of a reactor can be employed in systems and methods for carrying out the liquid-phase oxidation of an oxidizable compound, such as para-xylene.
