Patent number: 5304234Abstract: A gas separation process and a unit therefor. The process comprises the steps of: introducing a gas consisting of two or more components into an adsorption system in which adsorbent particles circulate in a fluidized state, thereby to allow, at atmospheric pressure or an elevated pressure, the adsorbent particles to adsorb a gas component to be separated from the gas; transferring the adsorbent particles adsorbing the gas component to a desorption system; and then desorbing the gas component from the adsorbent particles in the desorption system which is regulated to have either a lower pressure or a lower pressure and a higher temperature than the adsorption system.Type: GrantFiled: August 31, 1992Date of Patent: April 19, 1994Assignee: Chiyoda CorporationInventors: Toru Takatsuka, Ryuichiro Kajiyama, Yoshimi Okada, Seiya Hirohama, Tetsuo Shibagaki, Toshio Kushida

Patent number: 5284983Abstract: Disclosed is a purification process for removing lipophilic impurities coined in an aqueous crude ethanol solution, in particular, for efficiently removing impurities consisting of C.sub.3 -C.sub.4 alcohols. The process involves (a) a first extraction step wherein the aqueous crude ethanol solution is extracted with an extractant for removing the lipophilic impurities, except for the C.sub.3 -C.sub.4 alcohols, contained in the aqueous crude ethanol solution by subjecting the aqueous crude ethanol solution to extraction with the extractant in a pressurized state containing carbon dioxide in a liquidized state or carbon dioxide gas in a supercritical state; (b) a concentration-distillation step wherein a raffinate obtained in the first extraction step is fed to a distilling column to thereby obtain a highly concentrated aqueous ethanol solution from a top of the distilling column and withdraw fraction containing C.sub.3 -C.sub.Type: GrantFiled: February 3, 1993Date of Patent: February 8, 1994Assignee: Basic Industries Bureau of Ministry of International Trade and IndustryInventors: Tsunehisa Muto, Futoshi Kanegae, Toru Takatsuka, Seiya Hirohama, Masazumi Ojiro

Patent number: 4836909Abstract: A process of thermally cracking a heavy petroleum oil wherein the heavy petroleum oil is treated successively in a cracking furnace and then in a perfect mixing type tank reactor. The thermal cracking in the cracking furnace is performed at a temperature at the outlet of the cracking furnace of 450.degree.-520.degree. C. with a conversion of at least 60-75% of the overall conversion rate while the thermal cracking in the tank reactor is performed at a temperature of 400.degree.-450.degree. C. a pressure of from ambient pressure to 1 kg/cm.sup.2 for a period of time of less than 30 minutes but not less than 10 minutes while feeding steam having a temperature of 435.degree.-700.degree. C. to the tank reactor in an amount of 8-20% by weight of the heavy petroleum oil fed to the cracking furnace.Type: GrantFiled: September 9, 1987Date of Patent: June 6, 1989Assignee: Research Association for Residual Oil ProcessingInventors: Itaru Matsuo, Yuzo Takahashi, Hideo Hashimoto, Toru Takatsuka, Takeru Iimori, Hitoshi Maekawa, Tamotsu Ito, Yoshihiko Shohji, Ryuzo Watari, Hiroshi Aida

Patent number: 4487686Abstract: A heavy hydrocarbon feed stock is, after being heat-treated in a first cracking zone, is introduced into a second thermal cracking zone for obtaining a thermally cracked product and a pitch product. The second cracking zone has a plurality of cracking reactors which are connected in series, through which is successively passed the treated feed stock and to each of which is supplied a gaseous heat transfer medium to maintain the liquid phase therein at a temperature sufficient for effecting the thermal cracking and to strip the resulting distillable, cracked components from the liquid phase. The thermal cracking temperature in one reactor is so controlled as to become higher than that in its adjacent upstream-side reactor. The distillable, cracked components in respective reactors are removed overhead therefrom and separated into a heavy fraction and a light fraction, while the liquid phase in the downstream-end reactor is discharged therefrom for recovery as the pitch product.Type: GrantFiled: February 24, 1984Date of Patent: December 11, 1984Assignees: Fuji Oil Company, Ltd., Fuji Standard Research, Chiyoda Chemical Engineering & Construction Co., Ltd.Inventors: Shimpei Gomi, Tomio Arai, Tomomitsu Takeuchi, Shigeru Miwa, Toru Takatsuka, Ryuzo Watari
