    摘要: A unit for hydrorefining of hydrocarbon crude oil comprising sulfur-containing compounds comprises first catalyst layer 33 and second catalyst layer 38, top space 34 for separating vapor component and liquid component, bottom space 36, and valve tray 35 that divides top space 34 and bottom space 36. Hydrogen released from hydrogen nozzle 40 placed in the bottom space is passed through liquid component that has accumulated in the valve tray and stripping of liquid components is performed. Hydrogen released from hydrogen nozzle 40 is again introduced, to second catalyst layer 38 as a cocurrent with the stripped liquid component. By stripping, it is possible to reduce the sulfur content, the nitrogen content and reduce the aromatic content of the hydrocarbon crude oil when compared to the conventional method. Since the hydrorefining unit has a simple structure, the unit can be easily made by modifying existing units.

    摘要: A data multiplexing system which includes a plurality of data multiplexing buses through which a plurality of low-speed digital signals are collected into, and distributed from, a multiplexer/demultiplxer. In a data multiplexing mode, the low-speed digital signals entered from a plurality of low-speed transmission lines have their signal format converted by respectively corresponding low-speed interface circuits, and the resulting signals are multiplexed in time slots designated within a multiplexed signal of primary level on the up bus line of the corresponding data multiplexing bus. The high-speed multiplexer multiplexes the collected signals up to a predetermined signal level and sends the resulting secondary multiplexed signal to a high-speed interface module having a high-speed transmission line interface. The high-speed interface module converts the received secondary multiplexed signal and sends the resulting signal to the high-speed transmission line. The signal of the high-speed transmission line is processed by the high-speed interface module and the high-speed demultiplexer, and the low-speed digital signals are sent to the low-speed transmission lines.

In a data multiplexing mode, the low-speed digital signals entered from a plurality of low-speed transmission lines have their signal format converted by respectively corresponding low-speed interface circuits, and the resulting signals are multiplexed in time slots designated within a multiplexed signal of primary level on the up bus line of the corresponding data multiplexing bus, under the controls of respectively corresponding bus control circuits. The high-speed multiplexer collects the primary multiplexed signals on the up bus lines of the plurality of data multiplexing buses, and further multiplexes the collected signals up to a predetermined signal level. Thereafter, it sends the resulting secondary multiplexed signal to a high-speed interface module having a high-speed transmission line interface. The high-speed interface module converts the received secondary multiplexed signal so as to match the interface of a high-speed transmission line, and sends the resulting signal to the high-speed transmission line. In a data demultiplexing mode, the signal of the high-speed transmission line is processed by the high-speed interface module and the high-speed demultiplexer, and the resulting signals are distributed through the down bus lines of the data multiplexing buses so as to send the low-speed digital signals to the low-speed transmission lines.

    摘要: An image region extraction capable of extracting an image of a significant moving object in a dynamic image accurately and easily at high speed. The operator is required to manually enter the rough boundaries for the significant region in the first two fields of the dynamic image only, and the subsequent extraction operation for each subsequent field of the dynamic image is carried out automatically according to the conjectured rough boundary obtained on a basis of the extraction regions for the two fields immediately preceding that field. The extraction region for the significant region is obtained from the rough boundary on a basis of an original image of a respective field of the dynamic image, and the extracted image of the significant region in each field of the dynamic image is obtained by multiplying the original image of each field and the extraction region for the significant region in each field.

    摘要: A hydrorefining catalyst of a hydrogenation active metal component supported on a refractory porous carrier has a median pore diameter determined by the nitrogen adsorption method of 8 to 20 nm, a pore volume determined by the nitrogen adsorption method of 0.56 cm3/g or greater, and a pore volume of pores with a pore diameter of 50 nm or larger determined by the mercury intrusion porosimetry method of 0.32 cm3/g or greater. Both the demetallizing activity and metal deposition capacity of the catalyst in hydrogenation and demetallizing of heavy oil are high. The hydrorefining catalyst is obtained by kneading a porous starting powder principally composed of &ggr;-alumina and having a pore capacity of 0.75 m3/g or larger and a mean pore diameter of 10 to 200 &mgr;m, molding and calcining, and supporting an active metal component on the product.

    摘要: A heavy oil is hydrorefined using a hydrorefining catalyst. A spent hydrorefining catalyst whose activity has decreased is heat treated (S1) and pulverized to obtained a regenerated powder (S2). This regenerated powder is fractionated according to its metal content (S3), formed (S6), dried (S7), and calcined (S7) to manufacture a regenerated catalyst whose volume of pores with a diameter of 50 to 2000 nm is at least 0.2 ml/g, and whose volume of pores with a diameter over 2000 nm is no more than 0.1 mL/g. Using this regenerated catalyst, a heavy oil containing at least 45 wt ppm vanadium and nickel as combined metal elements is hydrodemetalized, and the vanadium and nickel are recovered from the used regenerated catalyst (SS1). Through hydrorefining, the metal components are recovered more efficiently, and the spent catalyst can be reused to manufacture a regenerated catalyst that exhibits high reaction, activity.
