Title: Oxidative dehydrogenation of hydrocarbon with solid superacid catalyst
Inventor: BENJIYAMIN ESU UMANSUKII
IPC: B01J27/053
Filed: 1995-01-04
Abstract: PURPOSE: To advantageously carry out oxidative dehydrogenation of a hydrocarbon due to the ability to enhance the initial catalyst activity and periodically restore the catalyst activity according to the formation of an active carbon site on the catalyst surface by using a specific catalyst.  
     CONSTITUTION: An alkane or an alkylaromatic compound is brought into contact with oxygen and a solid superacid catalyst preferably at 600-800°F under 200-400 psia to thereby carry out the oxidative dehydrogenation. The alkane or the alkylaromatic hydrocarbon is converted into an alkene or an alkenylaromatic hydrocarbon. The liquid space velocity LHSV (1/hr) of the alkane charging is preferably 1-3 and the molar ratio of the O 2 /alkane is preferably 2-7. For example, sulfated zirconia, a sulfated titania or the like can be used as the solid superacid catalyst; however, the catalyst preferably contains a sulfated oxide or hydroxide of a metal selected form Fe, Co, Mn or the like.

IPC: H01L35/08
Filed: 1984-01-30
Abstract: PURPOSE:To obtain the titled elements having uniform thermoelectromotive force characteristics by forming thermocouple parts and heat generating parts formed by thin film patterns on the same substrate. CONSTITUTION:Four thermocouples which comprise junction parts J1-J4 of regions of p and n type amorphous semiconductor thin films as hot junctions are connected in series. In electrode regions C1 and C2, a thermoelectromotive force is produced when the temperature of junction parts J1, J3 and J2, J4 are different. Meanwhile, the thin film patterns forming regions R1 and R2 of resistance thin films for heating the junction parts J1, J3 and J2, J4 are formed. These two thin film patterns R1 and R2 are laminated on an insulating substrate through an insulating layer and a differential thermocouple element is formed. In this element, when high-frequency power is introduced into the region R1 from electrode regions T1 and T2 to generate heat and D.C. power is supplied to the region R2 from other electrode regions T3 and T4 to control the D.C. power so that a thermoelectromotive force between the regions C1 and C2 becomes zero, the D.C. power shows the introduced high-frequency power.

Filed: 1981-01-30
Abstract: PURPOSE:To easily correct a change in the outgoing direction of a synchrotron orbit radiation beam by a construction wherein an optical element for introducing a light from a light source into an entrance slit is made rotatable and its angle is set to make output of a detector for detecting intensity of the light maximum. CONSTITUTION:An optical element (e.g., pre-mirror) for condensing a light which has emitted from a storage ring and changed in its direction by a pre-mirror is arranged to be rotatable. A detector and a diffractin grating are disposed in an optical path passing through an incident slit. Changes in amounts of light passing through the detector and the incident slit are detected, and the optical element (e.g., pre-mirror) is rotated and selected to have a degree at which the amounts of lights become maximum. The diffracted light from the grating is takn out through an exit slit as a monochromatic light. By so doing, it becomes possible to easily correct a change in the outgoing direction of a synchrotron orbit radiation beam and hence to effectively utilize the incident light.
