Methods for investigating catalyzed pyrolysis?

During normal production, people generally don’t give this much thought, as most devices have their appropriate reaction depth; even if adjustments are made, they are only minor tweaks. More attention is paid to the product distribution. However, the book states that the ratio of \"(c1+c2)/i-c4\" is used to distinguish between catalytic cracking and thermal cracking reactions. C1 and C2 are characteristic products of thermalization, while isobutane (i-C4) is a product of the hydrogen transfer reaction, which is a characteristic reaction in catalytic cracking. In the normal catalytic cracking process, this ratio ranges from 0.6 to 1.2; a value of <0.6 indicates that catalytic cracking is the dominant process, while a value >1.2 suggests that the cracking reaction is too intense. This applies only to ordinary devices; devices such as DCC may have a value greater than 1.2. There is also a measure of the degree of intensification based on the butadiene content; as the butadiene content increases, the intensity increases as well. It is also possible to use the ratio of C4/(C3+C4) in liquefied gas to determine the degree of intensification; a value of 0.65–0.7 indicates that catalytic cracking reactions dominate, while a value below 0.5 suggests a higher degree of intensification.
