Title: Catalyst for hydrolyzing carbonyl sulfide and hydrolysis
Inventor: NOJIMA SHIGERU
IPC: B01J27/232
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To convert carbonyl sulfide having numbers of base points into hydrogen sulfide by hydrolysis by adding a metal sulfate or a metal carbonate as a cocatalyst to anatase type titanium. SOLUTION: As a method for highly activating a TiO2 carrier, the addition of a cocatalyst is considered. The addition of a metal sulfate and a metal carbonate as a substance of a stable structure is considered. Besides, conversion into a complex oxide is cited to improve the performance of the TiO2 carrier. In general, by the conversion of a metal oxide into a complex metal oxide, the specific surface area increases, and also the heat resistance is improved. Also, solid base points increase. Although the form of a catalyst used in this reaction is not specified, a honeycomb-shaped catalyst is preferable. This catalyst added with a cocatalyst is prepared by a method in which metatitanic acid or titania, a metal sulfate, and a metal carbonate are added, and the mixture is added with a binder, kneaded, molded into a honeycomb, dried, and baked.

Title: Formation of heat-insulating synthetic wooden board
Inventor: NISHIBORI SADAO
IPC: B27N3/08
Filed: 1984-04-27
Abstract: PURPOSE:To obtain a heat-insulating synthetic wooden board free of warping and distortion by a method in which a cellulosic short fiber is mixed with a reinforcing fiber such as glass fiber, etc., and the mixture is pressed under high pressures for molding. CONSTITUTION:A cellulosic base material (e.g., wood chips, pulp, etc.) is cut into short fibers and beaten into cottony material to form an aggregate 1 having many raising portions 1a on its surfaces and having sizes of about 60 mesh. The aggregate 1 of short fibers is mixed with an inorganic reinforcing fiber 2 (e.g., glass fiber or carbon fiber mainly) to form a mixed material. The mixed material is hot- or cold-pressed to bring about the integral adherence of the aggregates 1 and the entanglement of the fibers 2. Since expansion and contraction caused by the swelling of the aggregate 1 are absorbed by the raising portions 1a, the occurrence of warping and distortion of the synthetic wood board can be prevented.
