Title: Coal liquefaction and reaction column for coal liquefaction
Inventor: MOCHIZUKI MICHIHARU
IPC: C10G1/06
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To enable the long-term, stabilized, and continuous running of a coal liquefaction plant by preventing the operation troubles such as blockage of pipping and valves caused by sticking of solid substance formed in the liquefaction reaction column onto the wall surface of the liquefaction reaction column and release of the sticking solid substance, when coal liquefaction reaction is carried out in the process. SOLUTION: This coal liquefaction process is carried out by pressurizing and heating a slurry containing coal, a solvent for liquefying coal, a catalyst for coal liquefaction in the presence of hydrogen and the liquefied oil is distilled and a part of the products is hydrogenated and recycled. In this case, circular mark or spiral mark are grooved on the wall surface of the liquefaction reaction column to make the flow of the liquid phase turbulent on the wall face thereby preventing solid substance from sticking to the wall surface. As a result, the operation troubles such as blockage of piping and valves caused by peel off of solid substance from the wall surface of the reaction column can be prevented and enable the long-term continuous stabilized operation of the coal liquefaction plant and reduction of its running cost.

Abstract: PURPOSE:To permit change of an optical path with a large angle by adhering silicone tightly to another material having smaller temp. coefft. of refractive index than silicone, and changing at least the temp. of the silicone with a temp. changing means. CONSTITUTION:When a heater 15 is ON, silicone rubber 14 is heated and a large difference of refractive index is generated between waveguides 12, 13. In this case, the area heated by the heater 15 is so wide as compared to the area of the silicone rubber 14 that a part of the waveguides 12, 13 is also included in the heated area, but the change of the refractive index of the waveguides 12, 13 are negligible as compared to the change of the refractive index of the silicone rubber 14. Therefore, almost all of the light l11 is reflected totally at the boundary face of the waveguide 12 and the silicone rubber 14 even if the light is incident with a small angle of incidence, and proceeds as light l13 through the waveguide 13. By this method, the optical path is changed with a large angle.
