THERMALLY STABLE MONOLITH CATALYST FOR REFORMING REACTION
The present invention relates to a monolith catalyst for reforming reaction, and more particularly, to a thermally stable (i.e. thermal resistance-improved) monolith catalyst for reforming reaction having a novel construction such that any one of Group 1A to Group 5A metals are used as a barrier component in the existing catalyst particles to inhibit carbon deposition occurring during the reforming reaction in a process for formation of a reforming monolith catalyst while improving thermal durability as well as non-activation of the catalyst due to a degradation.
Method for producing aqueous zirconium chloride solution
A method for producing an aqueous zirconium chloride solution includes: grinding zircon sand to an average particle diameter of 10 m or less; adding a sodium compound to the ground zircon sand to thereby obtain a mixture; firing the mixture in an iron container at 400 C. or less to thereby obtain a decomposed product; firing the decomposed product in a stainless-steel container at 400 to 1,100 C. to thereby obtain a fired product; dispersing the fired product in water to prepare a dispersion, and washing the fired product with water while adjusting the temperature of the dispersion to 70 C. or less, thereby obtaining a water-washed cake; washing the water-washed cake with hydrochloric acid with a pH of 1 to 6 to thereby obtain zirconium hydrate; and dissolving the zirconium hydrate in hydrochloric acid, and then removing insoluble components to thereby obtain a salt solution.

Water treatment composition and method of using same
A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.
METHODS AND SYSTEMS FOR STRONTIUM IMPURITY EXTRACTION
Provided herein are methods and systems for extracting zirconium and/or other impurities from a strontium-containing mixture. A method for removing zirconium from a mixture including zirconium and strontium can include converting at least a portion of a Zr-containing precursor to ZrF.sub.4 in the mixture, converting at least a portion of a Sr-containing precursor to SrF.sub.2 in the mixture, solubilizing at least a portion of the ZrF.sub.4 and/or the SrF.sub.2 in a solvent to create a solution, and/or separating at least a portion of the solubilized ZrF.sub.4 and/or at least a portion of the solubilized SrF.sub.2 from the mixture.
