WebProblem 8-6 (Level 2) Methyl cyclohexane (MCH) is being dehydrogenated to toluene (T) in a catalytic, fluidized-bed reactor. The feed to the reactor is a 2/1 (molar) mixture of H2 and MCH at a temperature of 500∘C and atmospheric pressure. The feed rate of MCH is 2.0lb⋅mol/s. The reactor contains 20.0 lb of catalyst and operates adiabatically. WebThe reaction of n-hexane to cyclohexane (or indeed methylcyclopentane) is a dehydrogenation step. Simple evidence would be the molecular formulae: C6H14 → …

Problem 8-12 (Level 2) Methyl cyclohexane (MCH) is being dehydrogenated to toluene (T) in an ideal, plug-flow reactor that is packed with catalyst particles. The feed to the reactor is a 20/1 (molar) mixture of H2 and MCH at a temperature of 500∘C and atmospheric pressure. The feed rate of MCH is 1000 gmoV/s.
WebWe would like to show you a description here but the site won’t allow us. WebDehydrogenation is conducted at moderately high temperature for both processes, but while this heat is effectively retained in the ammonia process (where the primary byproduct is gaseous nitrogen), it is not in MCH process, where gaseous toluene must be returned to liquid state via a process that does not lend itself as well to heat retention.
WebCyclohexane dehydrogenation, similar to other dehydrogenation reactions, is an endothermic and equilibrated reaction, which means that its conversion is limited to thermodynamics and increases with temperature. Temperature increases mean higher energy consumption and an increase in side reactions and coke formation.
