  • Process for thermal cracking of heavy petroleum oils
    Patent number: 4490243
    Abstract: In a process for thermal cracking of heavy oils in which a heavy petroleum oil is caused to contact a heated fluidized bed of solid particles in the presence of steam thereby to obtain principally light petroelum oils, the solid particles are stable at the temperature of the thermal cracking and are of substantially spherical shape of porous nature of a pore volume of 0.10 to 1.0 cm.sup.3 /g, a specific surface area of 50 to 1,500 m.sup.2 /g, and a weight-mean diameter of 0.025 to 0.25 mm.
