    摘要: A non-volatile memory including a logical/physical address control table for controlling data recorded discretely in the non-volatile memory composed of a plurality of blocks each serving as a data deletion unit and including adjacent pages which each have a fixed length and serve as a data read/write unit. An operand data block includes operand identification data that indicates data stored in the operand data block is, in fact, operand data. The logical/physical control table block located in the non-volatile memory includes control-table identification data that indicates that data that is stored therein is, in fact, control table data that includes logical addresses and physical addresses.

    摘要: The present invention is a process for producing styrene by dehydrogenation of ethylbenzene, which contains the steps of (i) feeding a raw material gas containing ethylbenzene and steam to a first dehydrogenating step to produce a reacted gas containing ethylbenzene, styrene and hydrogen in the presence of a dehydrogenation catalyst, (ii) feeding the reacted gas obtained in the first dehydrogenating step to an oxidizing step to combust at least part of hydrogen in the presence of an oxidation catalyst, and (iii) feeding the reacted gas obtained in the oxidizing step to a second dehydrogenating step to produce styrene from ethylbenzene in the presence of the dehydrogenation catalyst, with maintaining the carbon dioxide-generating ratio in the second dehydrogenating step at a level less than 2.1 times that at the initial stage of the reaction.
