摘要:
Methods and systems for reducing mercury emissions from fluid streams having a high concentration of sulfur oxide species are provided herein. In embodiments, mercury is removed from flue gas streams containing sulfur trioxide (SO3) by injecting a dry admixture of a porous mercury adsorptive material and at least one dry agent into the flue gas stream.

摘要:
Provided is a method for producing a porous material, wherein porosity can be controlled to 50% or higher by means of a freezing method, pore size can be controlled to 10 µm to 300 µm, and pore diameter distribution is uniform. The method is a method for producing a porous material, comprising freezing a mixture of water and a raw material comprising at least any of a ceramic material, a resin, a metal, and precursors thereof from a specific portion of the mixture to use ice crystals produced at the time as a pore source and then heat-treating a dry material obtained by removing the ice from the frozen material, wherein the mixture of a raw material and water or the frozen material comprises an antifreeze protein.
摘要:
The application relates to the particulate water absorbing agent of the present invention composed primarily of a polyacrylic acid- or polyacrylate-based water absorbing resin and containing a chelating agent and a phosphorous compound. Accordingly, the particulate water absorbing agent composed primarily of a water absorbing resin achieves both excellent water absorbing properties and anti-coloring effect which would normally be incompatible. A particulate water absorbing agent for absorbent core is provided that is suitable for actual use.
