Sažetak
The influence of catalyst type, temperature, and feedstock, on the distribution of catalytic cracking products has been determined. The experiments have been performed according to the microactivity procedure MAT ASTM D-3907, with two commercial fluid catalitic cracking (FCC) catalyst and two gas oils as feedstock, at C/O ratio from 2,25 to 3,75, and in the range of 482-520 C. The effects of catalyst and feedstock properties on gasoline and liguefied petroleum gas (LPG) yields were established from the selectivity curves. Also, the influence of these parameters on the LPG composition and its applicability to alkylation and oxygenate production was determined in relation to the P/O ratios, as well as the coorresponding isomerization/hydrogen transfer ratios. The temperature effects were in accordance with the thermodynamics of main catalytic cracking reactions.
