| Abstract: | The article analyzes a basic reason of heavy crude with high viscosity and high colloid asphalt content. Aiming at the characteristics and the problem present in normal oil. transportation process, it puts forward a new thinking: plant catalytic cracking and visbreaking. The main purpose for catalytic cracking is to degradate big molecules in heavy crude with many carbon content into small molecules in heavy oil with a few carbon content. The article expounds the principle of heavy crude catalytic cracking and visbreaking, and p'oints out that the key of this new technical thinking is to select a kind of low temperature and high efficiency heavy crude catalytic cracking agent, select heat driven method, arrange the equipment of heavy crude catalytic cracking at plant layout and planning. |
