摘要： In a reactor for cracking heavy hydrocarbon oil through a fluidized bed of the particles of natural ores, coke-like materials are deposited on a top of the reactor or pipe inside surfaces of a transfer line from the reactor to a scrubber. To effectively scour out the deposited coke-like materials, particles of natural ores having a mean diameter of a few hundred .mu.m is made to be contained in an effluent gas from the top of reactor, passing through the transfer line at a concentration of 1 to 40 g/m.sup.3. The particles of natural ores have a good effect of scouring out the deposited coke-like materials and can keep the transfer line efficiently clean even with a small amount of the particles of natural ores, decreasing a pressure drop in the transfer line.

摘要： A process for producing a cracked distillate and hydrogen from a heavy oil which comprises cracking the heavy oil in the presence of laterite or a laterite-containing catalyst while simultaneously depositing coke on said laterite or laterite-containing catalysts, reducing the laterite or laterite-containing catalyst on which the coke is deposited, and forming a hydrogen-rich gas by contacting the reduced laterite or laterite-containing catalyst with steam.
