A diffuser object for a flue gas desulfurization (FGD) absorber is described. The diffuser object is placed in a high flue gas velocity zone inside the absorber in order to better distribute the flue gas and improve absorption efficiency. A method of improving absorption efficiency in a FGD absorber is also described. The method involves identifying high and low velocity zones within the absorber and positioning diffuser objects within the high velocity zones in a non-packed manner. The placement of the diffuser objects and configuration of the objects are calculated to equalize flow rates within the absorber.

The invention relates to a method for the heterogenically catalyed gas-phase partial oxidation of precursor compounds of (meth)acrylic acid in a fixed catalyst bed, containing as the catalyst an activated mass of mixed oxide, shaped to form a geometric body. Said geometric body is a geometric base body, into whose surface a cavity is incorporated.

The present invention relates to a dual functional catalyst having both the catalytic reaction function and fractionation function and a catalytic distillation equipment for packing the catalyst therein. Said catalyst has a special shape and can be packed at random into the reaction section of said equipment. So, there exist adequate free spaces inside pellet and between pellets, enabling the vapor and liquid streams to pass through the catalyst beds directly and countercurrently, and contact with the dual functional catalyst directly. The reaction between the reactants and fractionation of products can be carried out simultaneously. Thus a high reaction efficiency is achieved. No special inner part is needed in the reaction section to pack the catalysts, so the structure of the equipment is simple and easy to operate, and the investment and cost of operation are low.
摘要:
Catalyst elements are shaped to provide large surface area per unit of volume (porosity), while providing high packing density. Generally, the elements are characterized by more than six faces of identical size and shape, and by members extending outwardly in three dimensions. Each element includes a plurality of concave regions defined by the intersection of various of their planar surfaces, yet is not simply a section of an extrusion.

A compressible biomass carrier for use in fluid treatment systems is disclosed. The biomass carrier includes an extruded circumferential mesh-like structure and elongated elements positioned in a space confined by the circumferential mesh-like structure and at least some of the elongated elements are joined to an inner portion of the mesh-like structure.
