Coking problem

Will a mixture of saturated and unsaturated hydrocarbons ranging from C1 to C7+ coking at around 400 degrees? (Note: Gas from the MTP reactor)
On the other hand, for heat transfer media used in chemical plants, hydrocarbons with a stable molecular structure, high bond energy, and a high boiling point (allowing operation at atmospheric pressure) are generally chosen – to be used as heat transfer oils. At present, the highest temperature at which liquid-phase synthesized heat transfer oils can be used is below 350 degrees Celsius. Mineral oil generally has a maximum temperature of around 280–300 degrees; it has a short service life and tends to form scale and coke. On the other hand, it’s certain that the substance you mentioned will coking if exposed to such high temperatures for an extended period of time.
Okay, so when choosing heat exchangers, if they have the flow in the shell side, it is easier to clean them. .
