Process and rotary machine type reactor
First Claim
1. A shock wave reactor for thermal cracking of hydrocarbon-containing feedstock, comprising:
- a casing wherein a duct is formed with at least one inlet and at least one outlet;
a rotor, the periphery of which contains an axial-flow blade cascade;
wherein the casing substantially encloses the periphery of the rotor and a number of stationary vane cascades inside the duct, and further wherein the stationary vane cascades are configured to direct a feedstock containing process stream to repeatedly pass said stationary vane cascades in accordance with a helical trajectory while propagating within the duct between the inlet and outlet and to generate stationary shock-waves to heat the feedstock.

Abstract
A rotary machine type shock wave reactor suitable for thermal cracking of hydrocarbon-containing materials includes a casing, a rotor whose periphery contains an axial-flow blade cascade, and a directing rim, provided with at least two stationary vane cascades, adjoining an axial-flow rotor cascade, wherein the casing substantially encloses the periphery of the rotor and the directing rim. The cascades are configured to direct feedstock containing process stream to repeatedly pass the cascades in a helical trajectory while propagating within the duct between the inlet and exit and to generate stationary shock-waves to heat the feedstock. The axial-flow rotor cascade is configured to provide kinetic energy and add velocity to feedstock containing process stream, and the stationary vanes located downstream the rotor cascade are configured to reduce the velocity of the stream and convert kinetic energy into heat. The reactor may also process carbohydrate-and glyceride-based feedstock, and gaseous biomass matter.
