    • 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.

    • 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.

    • A catalyst carrier composed of a refractory inorganic oxide has a rotationally symmetrical shape having a hollow portion, such as a doughnut shape. An outer peripheral surface and the inner peripheral surface separating the hollow portion are linked by curved surfaces, and the height h of the carrier along the rotational symmetry axis is less than the outer diameter Do of the carrier. Using a catalyst having this carrier shape for a fixed bed makes it possible to prevent granular substances from causing catalyst plugging, and catalyst life can be extended because the catalyst-induced differential pressure increase is low even when granular substances accumulate on the catalyst. It is also possible to prevent the reaction fluid from undergoing channeling. Also provided is a hydrogenation reactor whose fixed bed is packed with the catalyst.
    • 由耐火无机氧化物构成的催化剂载体具有中空部分的旋转对称形状,例如环形。 分离中空部的外周面和内周面通过曲面连结,沿着旋转对称轴的载体的高度h小于载体的外径Do。 使用具有这种载体形状的催化剂作为固定床使得可以防止颗粒物质引起催化剂堵塞,并且即使在催化剂上积累颗粒物质时催化剂诱导的差压增加较小,也能够延长催化剂寿命。 还可以防止反应流体进行通道化。 还提供了一种氢化反应器,其固定床装有催化剂。
