Hydrocarbon penetration

What is the principle behind hydrocarbons in the acidic gases entering the sulfur production furnace penetrating through without being decomposed inside the furnace, reaching the catalytic conversion stage, and thereby causing catalyst deactivation?
It is mainly due to insufficient air supply to the sulfur production furnace, which results in incomplete combustion of hydrocarbons; this leads to the formation of carbon deposits on the surface of the catalyst in the converter, thereby causing the catalyst to become inactive. The general treatment method is to increase the bed temperature of the converter in order to treat the catalyst.
Reply to 2# hcw990811219: Simply put, is it carbon buildup that causes the catalyst to become inactive?
However, the regeneration temperature for carbon buildup can easily cause permanent deactivation of the catalyst!
