    摘要: The present invention relates to a process for supply of a polymerization catalyst component to a polymerization reactor which comprises: a. Providing a first stream comprising the catalyst component in a first line, which first line is connected to and downstream of a pump outlet or of a flow control valve, b. Providing a diluent stream in a second line, c. Contacting the first stream and the diluent stream to form a mixed stream and passing the mixed stream to a polymerization reactor, characterised in that the mixing of the first stream and the diluent stream takes place by providing the first stream from the first line and the diluent stream from the second line separately to a mixing chamber which has an enlarged cross-section compared to the first and second lines.

    摘要: A method for the heat treatment of granular solids includes initially introducing solids into a first reactor configured as a flash reactor or fluidized bed reactor where they are brought into contact with hot gases at temperatures in the range 500° C. to 1500° C. Next, the solids are passed through a residence time reactor in which they are fluidized. The residence time reactor is configured in a manner such that it has various regions which are separated from one another, from which the solid can be withdrawn in a manner such that it is provided with a variety of residence times in the residence time reactor.

    摘要: A chemical reaction method includes preparing a chemical reaction apparatus including a horizontal flow reactor partitioned into multiple chambers by multiple partition plates. A liquid content horizontally flows with an unfilled space provided thereabove. a microwave generator and a waveguide that transmits microwaves to the unfilled space are also included. The reactor is inclined such that, in each of the chambers, a weir height on an inlet side is higher than a weir height on an outlet side by at least an overflow depth at the partition plate on the outlet side. The content is flowed over each of the multiple partition plates inside the reactor. The content flowing inside the reactor is irradiated with microwaves. The inclination angle of the reactor is changed in each of the chambers so that a weir height on an inlet side is higher than a weir height on an outlet side.

    摘要: A chemical reaction method having steps of preparing a chemical reaction apparatus by partitioning an inside of a horizontal flow reactor into multiple chambers by multiple partition plates, and flowing a liquid horizontally with an unfilled space being provided thereabove, generating microwaves with a microwave generator, and transmiting the microwaves, with at least one waveguide, to the unfilled space in the reactor. Also forming a top portion of the partition plates act as a weir, inclining the reactor such that, in each of the chambers, a weir height on the inlet side is higher than a weir height on the outlet side by at least an overflow depth at the partition plate on the outlet side, flowing content over each of the partition plates inside the reactor, and configuring the weir heights of the partition plates in the reactor are the same in a state where the reactor is not inclined.
