Process for producing cracked distillate and hydrogen from heavy oil
First Claim
1. 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 catalyst, reducing the laterite or laterite-containing catalysts on which the coke is deposited while simultaneously burning the coke in a reducing atmosphere, and forming a hydrogen-rich gas by contacting the reduced laterite or laterite-containing catalyst with steam.

8. A fluidized bed process for producing a cracked distillate and hydrogen from a heavy oil which comprises introducing said heavy oil into a first reaction zone containing a fluidized bed of laterite or a laterite-containing catalyst at a temperature of about 450°
- to 600°
C. under a pressure of about 0 to 15 kg/cm2 G and simultaneously depositing coke on said catalyst, removing the cracked distillate from said reaction zone and circulating said coke deposited laterite catalyst to a second reaction zone wherein said coke deposited laterite catalyst is fluidized and reduced at a temperature of about 750°
to 950°
C. under a pressure of about 0 to 15 kg/cm2 G while simultaneously burning the coke in a reducing atmosphere, circulating said reduced laterite catalyst to a third reaction zone wherein said catalyst is fluidized and contacted with steam at a temperature of about 600°
to 950°
C. under a pressure of about 0 to 15 kg/cm2 whereby a hydrogen-rich gas is formed. - View Dependent Claims (9, 10, 15)
