Title: Short residence time coal liquefaction process including catalytic hydrogenation.
IPC: C10G1/06
Filed: 1981-04-02
Abstract: Normally solid dissolved coal product and a distillate liquid product are produced by continuously passing a feed slurry comprising raw feed coal and a recycle solvent oil and/or slurry together with hydrogen to a preheating-reaction zone (26, alone, or 26 together with 42), the hydrogen pressure in the preheating-reaction zone being at least 1500 psig (105 kg/cm2), reacting the slurry in the preheating-reaction zone (26, or 26 with 42) at a temperature in the range of between about 455 DEG and about 500 DEG C. to dissolve the coal to form normally liquid coal and normally solid dissolved coal. A total slurry residence time is maintained in the reaction zone ranging from a finite value from about 0 to about 0.2 hour, and reaction effluent is continuously and directly contacted with a quenching fluid (40, 68) to substantially immediately reduce the temperature of the reaction effluent to below 425 DEG C. to substantially inhibit polymerization so that the yield of insoluble organic matter comprises less than 9 weight percent of said feed coal on a moisture-free basis. The reaction is performed under conditions of temperature, hydrogen pressure and residence time such that the quantity of distillate liquid boiling within the range C5-454 DEG C. is an amount at least equal to that obtainable by performing the process under the same condition except for a longer total slurry residence time, e.g., 0.3 hour. Solvent boiling range liquid is separated from the reaction effluent (83) and recycled as process solvent (16). The amount of solvent boiling range liquid is sufficient to provide at least 80 weight percent of that required to maintain the process in overall solvent balance.

Title: Compressed-air pile-driver
IPC: B25D9/08
Filed: 1982-03-26
Abstract: A compressed-air pile-driver, especially for axially insertable tools, including a ram arranged in a housing. The interior of the housing is divided by the ram respectively into an upper compression or expansion chamber and a lower compression or expansion chamber, which can each be alternately connected to a compressed-air source via air connection pipes and a control valve, with each having an air-outlet orifice opened alternately by the ram. In the upper expansion chamber, a pressure chamber, into which the upper air connection pipe of the upper expansion chamber opens, is divided off by an intermediate plate which is approximately parallel to the end face of the ram. Located in the intermediate plate is at least one orifice which connects the pressure chamber to the upper expansion chamber, and which is closed in a leak-proof manner by the ram in its upper dead-center position, the ram additionally being retained firmly in its upper dead-center position by a retaining device. Only when a pressure overcoming the retaining force of the retaining device is built up in the air-inlet orifice is the ram thrown explosively downwards, absorbing high energy in the course of short acceleration paths. The housing of the compressed-air pile-driver is injection-molded from plastic, preferably polycarbonate resins, in order to save weight and cost.
