1. A method comprising:
delivering heated resid fluid to a nozzle through a first conduit, and also delivering diluent fluid to the nozzle through a second conduit;
generating a stream of heated atomized resid fluid through the nozzle, which is a two-phase nozzle, a three-phase nozzle, or a capillary nozzle, wherein the stream comprises droplets independently having a diameter from 3 μm to 50 μm; and
delivering the stream to a plurality of cracking particles having a diameter of from 40 μm to 400 μm, wherein the plurality of cracking particles have a temperature from 700° C. to 1200° C. when the stream is delivered, wherein the droplets are smaller than the cracking particles by a factor of from 2 to 10.
