Cracked products gasoline

The cracked products pass out through two stages of cyclones which collect entrained catalyst and return it to the dense bed. Velocities at the outlet of the dense bed are normally 2.0-3.0 ft./sec. Upon leaving the cyclones, the vapors go to the primary fractionator which separates the heavy products from the gasoline and lighter components. The light products go on to the light ends recovery unit. The heavy material is separated and either recycled to the reactor or withdrawn from the system. [Pg.19]

Conversion is often defined as the percentage of fresh feed cracked to gasoline, lighter products, and coke. Raw conversion is calculated by subtracting the volume or weight percent of the FCC products (based on fresh feed) heavier than gasoline from 100, or ... [Pg.358]

As discussed previously, the ZSM-5 cracking products which occur outside the gasoline boiling range are mainly and olefins. The incremental olefin yield shows a higher... [Pg.68]

Other Properties. THERMAL STABILITY. Several attempts have been made to correlate knock resistance with thermal stability. Petrov (162) attempted to account for the knock characteristics of various gasoline fractions in terms of their cracking products. Rice (177) showed that a parallelism existed between yields of cracking products and knock tendency. Estradgre (60) did not find a direct relation between temperature for initial cracking and detonation characteristics. [Pg.191]

Crude oil is heated to temperatures at which it thermally cracks into gasoline and distillate products and lower-molecular-weight gases. This liquid cracking process is referred to as visbreaking. A schematic of the process and the effect of operating variables on performance is shown in Fig. 19-12. [Pg.21]
