    Abstract: A process for directly liquefying coal in a reactor including a preheating section and a reaction section, each having a plurality of pressure-resistant vertical pipes, comprises introducing into the preheating section a paste consisting of finely divided coal, catalyst and heavy oil. In the preheating section the paste is heated to a temperature of 380.degree. to 410.degree. C. and preheated hydrogen is blown into each pipe to create a velocity of Reynolds number equal to at least 3.times.10.sup.3 and an axial dispersion coefficient of not more than 0.05. The preheated paste and hydrogen are forwarded to the reaction section where they are heated to a temperature of 400.degree. to 500.degree. C. and further hydrogen is introduced into each pipe of the reaction section to maintain the velocity and axial dispersion values and a high partial pressure of hydrogen. The total quantity of hydrogen introduced is 1 to 3 times the stoichiometric value.

    Abstract: The gas to be polymerized is introduced into the working zone of a high pressure piston compressor and is compressed in timed relation to a pressure suitable for the polymerization. The gas temperature suitable for the polymerization process at the end of the compression stroke is set by cooling or heating the gas before the gas enters the compressor. The catalyst or initiator activating the polymerization is introduced into the working zone of the compressor during the compression stroke or after completion thereof, e.g. with the aid of a controlled injection valve. The gas containing the polymer and expanded approximately to the initial pressure is passed out of the compressor into a separator and is here freed from the polymer, while the residual gas is re-cycled to the compressor by means of a blower. For the polymerization of high-pressure polyethylene, the gas is compressed to a final pressure of about 2500 kg/cm.sup.2 at a temperature of about 130.degree. C. in the working zone of the compressor before introduction of the catalyst. The compressor may operate in a two-stroke or four-stroke cycle.

    Abstract: Lignocellulose is pulped batchwise by introducing it and the white liquor in predetermined quantity, together with a variable quantity of black liquor, into a continuously steam pressurized digester. When the cooking cycle has been completed, the pulp product is withdrawn. The time intervals of feed material introduction and pulp product withdrawal are correlated to insure that all of the lignocellulose charged to the digester is cooked uniformly, as by withdrawing the pulp product over a time interval which is substantially equal to the feed time. For economy and efficiency of operation, the digester preferably is operated in conjunction with one or more companion digesters to which it is connected. The first digester then is blown while a second digester is charged, making possible transfer of hot pressurized black liquor from the former to the latter.

    Abstract: A high-temperature, fluid-wall chemical reactor can be equipped with a variable profile, counterflow heat exchanger and a reaction product control system. The heat exchanger includes two tubular walls, positioned concentric of one another, and a spiral baffle disposed between the two walls to define a spiral, annular coolant channel. The walls and baffle are made of a refractory material. The heat exchanger has an inlet and an outlet to permit a coolant to be circulated through the coolant channel. The reaction product control system includes a reaction product analyzer and means for withdrawing and transferring samples of reaction product exiting the reactor. The reaction product analyzer can receive samples of reaction product and generate a signal corresponding to deviations between the chemical composition of the product and a preselected composition. The control system also includes a reactor temperature controller to vary a temperature of the reactor in response to the signal from the reaction product analyzer to reduce the deviations.
