The vapour and liquid phase alkylation of various reactions are studied over MnAPO-5 and MnAPC-11. The product distribution and selectivity are discussed in terms of dimensions of the molecules. The coke content, regeneration time required by the catalyst and TOS are studied. The studies suggest that a strong deactivation of the catalyst occurs with increase in bulkiness of the reactants. The vapour phase reactions carried out at high temperatures (350 and 400 degrees C result in faster deactivation of the catalyst, whereas the liquid phase reactions showed good conversion and extended catalyst life.
