โœฆ Synopsis

Studies of carbon deposition from aliphatic and aromatic hydrocarbons over metal catalysts were carried out over the temperature range 700-1025 K using a microbalance coupled with a tubular reactor. The influence of the nature of the reactor wall on the rate of carbon formation, as well as the effect of hydrogen in preventing deactivation of the catalysts, was investigated. A general reaction scheme is proposed to explain the relationships between the different types of carbon formed on the catalysts.

Primary causes of deactivation of hydrodesulfurization catalysts are partial poisoning of the interior pore surface and pore-mouth plugging by deposition of metals from organo-metallic compounds in the reactor feed. A model is developed to account for both causes of deactivation. It can be used to p
