Patent number: 8226921Abstract: The present invention provides a raw coke having such a structure that the graphitized product resulting from graphitization of the raw coke at a temperature of 2800° C. under an inactive gas atmosphere will have ratios of the crystallite size to the lattice constant of 360 or less in the (002) plane and 1500 or less in the (110) plane, as a raw coke providing active carbon produced by alkali-activating the raw coke, which is reduced in remaining alkali content and can simplify washing operation because washing liquid can easily pass through the activated carbon, or as a raw coke for the production of needle coke.Type: GrantFiled: June 10, 2011Date of Patent: July 24, 2012Assignees: Nippon Oil Corporation, Nippon Petroleum Refining Company, LimitedInventors: Takashi Oyama, Kazuhisa Nakanishi, Tamotsu Tano, Keiji Higashi, Ippei Fujinaga, Hiromitsu Hashisaka, Toshitaka Fujii, Takashi Noro, Akio Sakamoto, Kiwamu Takeshita, Keizou Ikai, Masaki Fujii, Hideki Ono

Patent number: 5376257Abstract: A process for feed oil refining for production of lubricating oil, by using an equipment for lubricating oil production including a fulfural refining unit, a hydrotreating unit and a ketone dewaxing unit, all connected in series. In this process, operations associated with the switch of feed oil are conducted by carrying out the first to seventh step groups successively. Each step group is initiated when a given time has passed since the start of the previous step group, or when the value of a particular measurement item has reached a target value, or when the value of a particular measurement item has shown a change. First, in the first step group, the amount of feed oil supplied to each unit, etc. is adjusted and, in the second step group, the feed oil to the furfural refining unit is switched.Type: GrantFiled: August 2, 1993Date of Patent: December 27, 1994Assignee: Nippon Petroleum Refining Company, LimitedInventors: Akinori Odan, Noboru Shimizu, Norihiko Ageishi
