Abstract

The paper studies the amount and structure of coke on coked and regenerated cracking catalysts used in industrial units. The temperature range of coke oxidation was established (the peak temperature is 515.6°C), which indicates the presence of an amorphous structure on the coked catalyst surface. The coke C/H ratio was determined using the calculation method based on the industrial plant regenerator flue gas composition analysis. This ratio varies in a wide range of 0.57-1.9 units. The efficiency of regeneration was determined by the amount of oxidized coke, which was 78.1 %.
