Abstract
A bladed reactor for pyrolysis of hydrocarbons comprises a rotor with blades that form an axial-flow blade cascade, a fixed torus-shaped hoop that adjoins the tips of the blades, and a housing that encloses the hoop and a rotor periphery so that a passage having a ring shape of its meridian section is formed. One or more partitions are installed in the passage, an inlet port is located directly after each partition while an outlet port is located directly in front of each partition. Nozzle vanes forming a nozzle cascade are installed upstream of the blade cascade, and diffusing vanes forming a diffusing cascade are installed downstream of the blade cascade. There is a vaneless space between the exit from the diffusing cascade and the entry into the nozzle cascade. A group of nozzle vanes arranged directly after each partition may be separated off from the remaining nozzle vanes by a bulkhead so that a channel is formed which connects the corresponding inlet port with separated group of nozzle vanes to simplify the reactor starting.
