Abstract
Experiments in the temperature range 390 °C to 537 °C have been carried out for the selective oxidation of propylene to acrolein and isobutylene to methacrolein quantitatively in a laboratory-scale, shallow fluidised bed of bismuth-molybdate catalyst (particle size 60–80 µm), and the optimum operating conditions determined. Uniformity of fluidisation was achieved by use of a stirrer within the catalyst bed. The minimum fluidisation velocity was derived and oxidation experiments performed at this and low superficial gas velocities.
Effects of bubble formation on conversion, selectivity to methacrolein, and yields of the by-products were measured. Kinetics of the reaction and catalyst studies and their part in the reactions were investigated. Carbon and oxygen mass balances were checked in order to determine the experimental error.
