    摘要: A process for producing an alcohol from a fatty acid ester, a fatty acid triglyceride or a fatty acid by continuously catalytically reducing the starting material in the presence of a hydrogenation catalyst is disclosed. In the process of the present invention, two reactors (i.e., the main reactor located upstream and the after reactor located downstream) being located in series are employed. In the process of the present invention, two reactors are employed and the temperatures thereof are individually controlled, whereby the conversion ratio is elevated while suppressing the formation of hydrocarbon and aldehyde by-products. Thus, an alcohol of extremely high quality and high purity can be produced. Further, the process of the present invention makes it possible to omit any post-treatment for eliminating the by-products. Furthermore, the active life of the hydrogenation catalyst can be remarkably prolonged by using three reactors (i.e., the guard reactor, the main reactor and the after reactor).

    摘要: A body frame for a motor bicycle includes a main frame, a head tube provided at a front end of the main frame and down tubes extending rearward from the main frame. The main frame, head tube and down tubes are cast with a light alloy into an integral form of a hollow and thin-wall structure. A production process of the body frame, wherein an integrally-formed core, which is formed into a shape similar to that of the body frame, is hollow and has good permability. A molten metal is charged into the mold and a vacuum is applied to the interior of the core. The molten metal is charged into a cavity defined between the core and the molding surface of the mold by a low-pressure casting method, and the molten metal is solidified so as to cast the body frame. A production apparatus of the body frame includes a liftable cope fitted to a vertical casting machine, a fixed drag, and slidable molds disposed in combination with the cope and being capable of horizontally sliding in a state that the cope is released from the drag. A body frame having both properties of light weight and high stiffness, and a production process and apparatus thereof is provided wherein casting defects and to provide a high-precision cast article, is provided.
