Two-years of experience in operating two type 43-102 cat crackers on the new Ts-100 industrial catalyst, which replaced Ts-10 catalyst without changing the conditions, are generalized. The yield of naphtha cut increased by 3-4 wt. % in this period, the sum of light cuts increased to 75-76 wt. %, and the motor octane number (MON) of the naphtha cut increased from 78 to 79.5 %. The catalyst consumption rate decreased from 1.9 to 1.6 kg/ton and the servicing interval increased to 1.5 years.
