It is comparatively modern technique. It is comparatively an older technique.
It is continuous process. It is batch process.
The catalyst is fluidized (i.e. in form of fine powder), circulated by air stream and is separated from the oil vapoues by means of cyclone. The catalyst has bigger particle size and is stationery.
The cracking temperature is 5000C. The cracking temperature is 4500×
The pressure of heavy oil vapors is 3-5. The pressure of heavy oil vapors is 1-5
