Abstract
Hydration of acetylene under steady-state conditions around 450 K proceeds on Cd-clinoptilolite without catalyst deactivation and formation of by-products. Reaction rates were determined under steady-state conditions at different partial pressures of acetylene, water, and acetaldehyde. In relation with the results, rate equations for different kinetic models were evaluated. Langmuir-Hinshelwood kinetics was established. According to this model, acetylene and water must adsorb on similar sites, and the surface reaction between the adsorbed reactants is the rate-determining step, which is followed by equilibrated desorption of the produced acetaldehyde.
