    摘要: Filtration of coal digest can be greatly facilitated by liquid phase extraction using an aromatic solvent oil of coal in at leasttwo stirred reactors in series. Control of residence time is greatly enhanced, reducing or eliminating short residence time digest components which increase filter cake resistivity and long residence time components which have repolymerised and cause loss of yield.

    摘要: A method is provided for testing the activity of a catalyst for a chemical reaction in which naphthalene is reversibly hydrogenated by gaseous hydrogen into tetralin, which avoids the need to pressurise a test vessel with hydrogen, enables simple apparatus to be used and gives good accuracy. Tetralin and catalyst are introduced into a sealed container (10), the container (10) is heated to a reaction temperature for a predetermined time, and the amount of naphthalene formed by dehydrogenation is determined. The method is applicable to the measurement of catalyst activity for catalysts used in the production by hydrogenation of coal-derived liquids.
