A sequential mixer for mixing a heated hydrocarbon stream and a supercritical fluid to produce an intimately mixed stream upstream of a supercritical reactor. The sequential mixer comprising a body having a body length and a body diameter; a hydrocarbon inlet physically connected to the body, having an inlet diameter, the hydrocarbon inlet is operable to receive the heated hydrocarbon stream into the sequential mixer; a mixed stream outlet physically connected to the body and fluidly connected to the supercritical reactor, having an outlet diameter; a traversing axis extending through the center of the body from the hydrocarbon inlet to the mixed stream outlet; a cross-sectional axis, the cross-sectional axis perpendicular to the traversing axis; and a plurality of fluid ports physically connected to the body, the plurality of fluid ports are arranged in a port alignment arrayed along the traversing axis, each fluid port has a port diameter and a port angle, the supercritical fluid is injected through the plurality of fluid ports; and a flow restrictor installed between each of the plurality of fluid ports.
