The differences between fluid bed catalytic cracking fixed bed catalytic cracking are as
| Fluid bed catalytic cracking | Fixed bed catalytic cracking |
|---|---|
| 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 |
| Kg/ cm2 | Kg/cm2 |
