Study of multiphase flow useful to understanding scaleup of coal-liquefaction reactors.
Report on the study of multiphase flow to understand further scaleup of coal liquefaction reactors, is given. Gas holdup measurements for air and water were made using the 13 inch acrylic column to test the equipment. The preliminary results indicate all the equipment and the experimental techniques work satisfactorily. Preliminary analyis indicates the use of porous plates as a gas distributor in the 6 inch column yield gas holdup values close to 0.25 at the bubble and bubble slug transition. A number of porous plates were used of different material, pore size and thickness. (from author's abstract) (Microfiche)
