If I was going for a soft drink, it would have to coke.
The deactivation could be due to coke deposition on acidic sites following multiple cracking [52].
Both reactions are endothermic and favored at high temperatures and susceptible to coke forming side reactions.
The relation can be easily extended to apply to coke deposition in continuous-flow reactors.
Deactivation processes occur upon dichloropropane conversion, mainly due to coke deposition.
However, use of propylene, as alkylating agent at very high temperatures leads to coke formation which results in deactivation.
The activity is however decreasing with time-on-stream due to coke deposits.
Nevertheless, furfural conversion decreased rapidly due to coke formation inside zeolite pores.
Modeling of the TAP data provides insight into the deactivation mechanism due to coke deposition.
At high temperatures, the heaviest components ("precoke") are converted to coke, which undergoes combustion.
Lignin pyrolyzed at higher temperatures yielded chars with greater order, similar in composition to coke.
