1. A reactor for centrifuge pyrolysis of a feedstock, the reactor comprising:
a cylindrical reactor vessel having a first end and a second end, and having an inlet proximal to the first end for receiving the feedstock and an outlet proximal to the second end for discharging at least one pyrolysis product;
a heated surface defining an inner wall of the cylindrical reactor vessel;
a cylindrical rotor concentric to the cylindrical reactor vessel along a longitudinal central axis, the longitudinal central axis being coincidental with an axis of rotation of the cylindrical rotor; and
at least one rotor blade coupled to the cylindrical rotor along a length of the cylindrical rotor such that the or each at least one rotor blade defines a respective plane that is angled away from a circumferential plane such that each of said respective planes defined by the or each at least one rotor blade is bisected by the circumferential plane, wherein the circumferential plane is a plane on which the axis of rotation of the cylindrical rotor lies and which bisects the cylindrical rotor lengthwise, wherein the axis of rotation does not lie on the respective planes defined by the or each at least one rotor blade, wherein the or each at least one rotor blade projects radially outwards from said cylindrical rotor, and wherein the or each at least one rotor blade is non-tangential to said cylindrical rotor;
wherein the cylindrical rotor is for rotation about the longitudinal central axis to impel a centrifugal force to the feedstock for contacting the heated surface to thereby result in the at least one pyrolysis product; and
wherein the or each at least one rotor blade is configured for facilitating propagation of the feedstock in an axial direction from the first end to the second end.
