    摘要: A process for the fluid catalytic cracking of a heavy fraction oil, which comprises the step of bringing the heavy fraction oil into contact with a catalyst containing an ultrastable Y-type zeolite, in a fluid catalytic cracking apparatus having a regenerating zone, a reaction zone, a separation zone and a stripping zone and under conditions that a reaction zone outlet temperature is in a range of 550 to 700°C, a catalyst/oil ratio is in a range of 15 to 100 wt/wt, and a difference between a regenerating zone catalyst concentration phase temperature (1) and the reaction zone outlet temperature (2) is in a range of 5 to 150°C. According to the fluid catalytic cracking process, an amount of dry gases generated by the thermal cracking of the heavy fraction oil can be lessened while a yield of light fraction olefins can be enhanced.

    摘要: A process for the fluid catalytic cracking of heavy fraction oils containing heavy metals such as Ni and V, which comprises withdrawing a portion of ferrite-containing catalyst particles circulating in a fluid catalytic cracking apparatus, separating the thus withdrawn catalyst particles into metals-richly deposited catalyst particles and metals-poorly deposited ones by using a magnetic separator and then returning the metals-poorly deposited catalyst particles, together with fresh ferrite-containing catalyst particles, into said cracking apparatus.
