摘要:
Disclosed herein is a method and apparatus for recovering hydrogen in the process of desulfurizing petroleum hydrocarbon, in which hydrogen is recovered from the fuel fraction obtained by hydrodesulfurization, and the recovered hydrogen is reused, so that the existing hydrodesulfurization equipment for producing ultralow-sulfur diesel fuel can be utilized to the utmost and simultaneously the effluence of hydrogen from fuel fraction can be minimized, thereby reducing production costs.
摘要:
A computer system using a common Basic input/output system for operation with different expansion adapters which comprises a setting block for setting information of whether expansion adapters are mounted in an expansion block, and a controller for determining whether the expansion adapters are set in the expansion block through signals from the setting block in order to disable execution of a Basic input/output system routine of the expansion adapter which is not set, and enable execution of the Basic input/output system routine related to the expansion adapter which is set.
摘要:
Polymeric compositions capable of forming stable micelles in an aqueous solution, comprising an amphiphilic block copolymer of a hydrophilic block and a hydrophobic block, and a polylactic acid derivative wherein one end of the polylactic acid is covalently bound to at least one carboxyl group. The carboxyl group of the polylactic acid derivative may be fixed with a di- or tri-valent metal ion, obtained by adding the di- or tri-valent metal ion to the polymeric composition.
摘要:
A computer includes a processing unit; a hard disk drive having a main memory region on and from which processing information used in correspondence to processing procedures of the processing unit is directly written and read; a control unit which communicates with the hard disk drive at high speed, for controlling the writing and reading for the hard disk drive; and a communications bus which connects between the hard disk drive and the control unit so that the hard disk drive and the control unit can communicate with each other at high-speed. Accordingly, there is provided a computer which effectively overcomes the limit on a memory storage capacity, and saves the space of a mainboard and reduces the weight thereof.
