Publication number: 20100217054Abstract: Disclosed is a method for production of lower olefins from a raw material containing dimethyl ether (DME), which can produce lower olefins (e.g. propylene) with good yield and in an economically advantageous manner by prolonging the time until the reversible deactivation of a zeolite catalyst and preventing the irreversible deactivation of the catalyst, can reduce the amount of water to be recycled to increase the thermal efficiency of the process, and can simplify the facilities and operations. Also disclosed is a method for improving the yield of propylene with good efficiency under practical operating conditions. A feed gas which comprises a DME-containing feedstock gas and an additive gas and further contains steam at a specific proportion is introduced into an olefin synthesis reactor to contact the feed gas with a zeolite catalyst, thereby producing a hydrocarbon product containing C2-C5 olefins.Type: ApplicationFiled: November 13, 2006Publication date: August 26, 2010Applicant: JGC CorporationInventors: Hirofumi Ito, Kazunori Honda, Koji Oyama, Nobuyasu Chikamatsu, Kazutaka Hiraoka, Atsushi Okita

Publication number: 20100013838Abstract: [PROBLEMS] To naturally and smoothly move a control target such as a virtual actor by using a small data amount and effectively perform data setting for it. [MEANS FOR SOLVING PROBLEMS] A computer system includes means for storing node data on a key frame and edge data such as a transition direction between nodes and a frame rate and execution means for shifting to another node by a morphing process determined by the edge data when shifting from one node to another node. Moreover, when inputting data, node icons are connected by an edge icon so as to enable effective data input. In data registration of the morphing process, feature line data is manually inputted for one image of an image pair and then a feature point in the vicinity of the both ends of the feature line is searched so as to automatically compensate the feature line data.Type: ApplicationFiled: August 27, 2006Publication date: January 21, 2010Inventor: Hirofumi Ito
