摘要： An agent for removing a halogen gas, such as chlorine, in a waste gas by means of reduction; a method for producing this agent; a method for removing a halogen gas by use of this agent; and a system for removing a halogen gas. The agent for removing the halogen gas contains at least pseudo-boehmite, that serves as a host material, and a sulfur-containing reducing agent, that serves as a guest material. 1-8% by weight of the reducing agent, in terms of elemental sulfur, based on the total amount of the pseudo-boehmite and sulfur-containing reducing agent is present in the agent. At least one inorganic compound selected from among oxides, carbonates salts and hydrocarbon salts of alkaline earth metal elements, transition metal elements and zinc group elements is additionally contained in the agent as a third component.

摘要： An adsorbent is provided to adsorb ruthenium from aqueous solution for recovery and/or reuse or removal of said ruthenium, and a method for purifying, for example, sea water and/or water containing sodium ions, magnesium ions, calcium ions, chlorine ions or other ions, polluted with a radioactive element, using said adsorbent.The ruthenium adsorbent includes manganese in the form of oxides thereof. The adsorbent can further include at least one additional transition metal element other than manganese, such as copper. The adsorbent soaked in water removes radioactive ruthenium or the like through adsorption, and thereby can purify, for example, sea water and/or water containing sodium ions, magnesium ions, calcium ions, chlorine ions or other ions.

摘要： A process for treating a petroleum fraction and for efficiently absorbing an organic halogen compound from a fluid mixture of the organic halogen compound and an inorganic halogen compound derived from crude oil. Also disclosed is an improvement in absorption performance of a halogen-compound-absorbing material, thereby reducing the frequency with which the absorbing material is exchanged. The absorbing agent includes attapulgite (palygorskite) having high absorption performance with respect to organic halogen compounds. Also disclosed is an absorption column in which the aforementioned absorbing agent and a halogen-compound-absorbing agent, that includes zinc oxide, are disposed in series, thereby making it possible to raise the treatment performance with respect to a fluid that contains, in high concentrations, the organic halogen compound in addition to the inorganic halogen compound.

摘要： A halogen gas removing agent for removing halogen gas from a gas flow, which reduces the risk of leakage of the halogen gas exhausted from a semiconductor production process by treating the gas flow with the removing agent and a process for producing the removing agent. Also provided are an apparatus for removing the halogen gas using the removing agent, and a method for monitoring the state of consumption of the halogen gas. The halogen gas removing agent includes an inorganic compound base material, a sulfur-containing reducing compound and a color indicator, preferably using a pseudoboehmite as the base material, adding a pH indicator having a transition range in a pH range of 3 to 8 as the color indicator, and adding a basic metal compound such as zinc oxide.

摘要： A catalyst for oxidizing a substance such as ethylene, carbon monoxide, or formaldehyde at high efficiency even at a low temperature of 100° C. or below, such as room temperature or below. Further, an oxidation catalyst of a low-temperature substance in which a noble metal and a metal halogen salt other than that of a noble metal are supported on a metal oxide carrier.

摘要： A method for manufacturing a catalyst that oxidatively decomposes ethylene, carbon monoxide, formaldehyde, etc., at high efficiency even at low temperatures, wherein discharge of harmful gases such as halogens during the manufacture is reduced. Further, a method for manufacturing a low-temperature oxidation catalyst including: (1) a step for causing a non-halogen-containing noble metal compound to be supported on a carrier; (2) a step for reducing the noble metal compound on the carrier obtained in step (1); (3) a step for causing a halide to be supported on the carrier obtained in step (2); and (4) a step for drying the carrier obtained in step (3) and obtaining a low-temperature oxidation catalyst.
