Title: Production of adsorbent with crystobalite, tridimite and their mixture as raw material
Inventor: MINAGAWA TETSUJIRO
IPC: B01J20/10
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To produce a functionally gradient adsorbent with two inside-high and outside-low adsorptivity species formed in one solid grain by applying necessary treatment to the crushed grain and solid grain produced from the raw material. SOLUTION: A granular solid produced from the crushed grain and powder of crystobalite, tridimite and their mixture is phosphated and heat-treated (kept at 870 deg.C for one hour and furnace-cooled, for example) to form two species having a different adsorptivity in one solid grain. Each formed layer has a high-adsorptivity core and low-adsorptivity shell, and the adsorbed component is not accumulated but diffused inward. The discharge of the internally adsorbed component to the periphery is minimized, an efficient action is revealed, and the adsorbent is semipermanently utilized with a simple treatment.

Inventor: YONEMOTO TAKAHARU
IPC: C23C8/36
Filed: 1985-11-13
Abstract: PURPOSE:To make an electrolytic current go down and improve a removal rate, by letting a copper-based electrode wire pass through the inside of oxygen low temperature plasma, forming an oxide film on its surface, and oxidizing the surface without entailing any drop in the strength. CONSTITUTION:A Cu-30% Zn alloyed wire 9 extended to 0.2mm in diameter as an electrode wire is pickled prior to treatment and washed clean and dried up. On the other hand, it is deaerated by a vacuum pump 11, feeding it with 100% oxygen by a gas cylinder 6, and a gas flow rate is set to a range of 500cc/min., taking in a microwave of 24.5GHz and output 500W from an microwave generator 1. And, when the wire 9 is passed through the inside of a reaction pipe 3, temperature of the wire 9 is 180 deg. in the measured result by an infrared radiation thermometer, and its surface color is changed to black, thus formation of an oxide film is confirmed. In consequence, the surface of the electrode wire is smooth, and its tensile strength remains unchanged prior to treatment so that a removal rate can be improved as much as 33% over.

Title: Production of emulsified heavy oil fuel
Inventor: IIZUKA MASANORI
IPC: C10L1/32
Filed: 1992-09-24
Abstract: PURPOSE:To obtain an emulsified heavy oil fuel of excellent stability by emulsifying a heavy oil, water, a specified precursor and a neutralizing agent or a saponifying agent for the precursor while forming an emulsifier. CONSTITUTION:This fuel is produced by emulsifying 60-85wt.% heavy oil, 10-40wt.% water, 0.01-10wt.% carboxylic compound or an ester as a precursor for an emulsifier and 0.01-5wt.% neutralizing agent or saponifying agent for the precursor while forming an emulsifier by reacting the precursor with the neutralizing agent or the saponifying agent.
