| Abstract: | Tremendous increase in the production of petrochemicals, plastics, and synthetic fibers have caused an expanding demand for ethylene. Alternate sources for production of ethylene are being seriously considered as the conventional source, naptha, has become scarce and expensive. The most promising of the new processes for ethylene manufacture seems to be the catalytic conversion of methanol to ethylene. A lot of work has been done in this area by Dr. Anthony Using a Berty reactor. To improve the ethylene selectivity and to study the catalyst essensialy at constant activity, it was desirable to develop a fluidized bed system. In this work, a fluidized bed system of plexiglass was designed and constructed to conduct cold flow study. Best design and operating conditions to obrain good fluidization were determined. Three different porous distributor plates were examined and the one giving unifom distribution of gas and hence a very good fluidization was selected. Optimum particle size distribution of catalyst to obtain good fluidization was determined. The bounderies of operation, the lower one defined by minimum fluidization and upper one defined by begining of slugging, were also determined. Various correlations for design of distributor plates, prediction of minimum fluidization velocity and prediction of slugging condition were examined and most reliable design criteria were determined. A technique for continuous feed and withdrawal of catalyst was developed. |
