Abstract

A process is described for FCC middle distillate maximization comprising the use of two distinct converters, which are operably coupled, said process aiming to maximize the production of LCO for diesel, generate a specific gasoline and decrease fuel oil production. Converter "A" operates with low contact time in the riser, from 0.2 s to 1.5 s (preferably from 0.5 s to 1.0 s), enabling a higher reaction temperature, even when there is low severity, of 510°C to 560°C (preferably 530°C to 550°C), and with a suitable catalyst for maximizing LCO. Converter "B" has a high-activity catalytic system, which is suitable for cracking the naphtha and DO generated in the first converter. Preferably, converter "B" has two separate risers, which makes it possible for the reaction temperatures of each riser to be independently adjusted according to the most recommended range for maximizing cracking of each of the flows: 530°C to 560°C for the DO riser and 540°C to 600°C for the naphtha riser. The high-quality LCO flow generated by the low-severity cracking in converter "A" is not contaminated with the lower quality LCO generated by DO re-cracking in converter "B", since each converter has its own fractionating tower. The use of low contact time as a means for reducing severity in converter "A" with the intention of producing better quality LCO allows said converter to operate at a higher reaction temperature for the same level of conversion and LCO quality, resulting in greater operational reliability of the unit, as well as benefiting the heat balance of the converter. In existing units, the heat balance improvement allows the air blower to rest by increasing feedstock temperature, and also allows cruder feedstock to be processed.
