31b.3 Technical Questions
1. Discuss the detailed process related to the gas liquid hydrogenation reaction ?
Ans: For gas liquid reaction in hydrogenation
A series of rate process and 8 kinetic reaction exist as shown in fig below:
For many hetrogenous catalytic reactions, the rate behavior is characterized by:
-
• Surface reaction and adsorption controls the reaction rate at 100°C.
• Rates increases as H2 pressure increases (at the max 7 atm gage)
• At 180°C, mass transfer for solution of H2 and diffusion to and from catalyst are rate controlling steps.
