摘要:

A high volatile bituminous coal was pyrolyzed by use of microwave energy and by traditional convective heating. In both cases the pyrolysis was conducted under vacuum to facilitate product recovery. The gas and liquid fractions produced on pyrolysis were analyzed by means of gas chromatography.

摘要:

The present work analyzes the process of mass transfer with chemical reaction in a system formed by a periodically curved catalytic wall, which is wetted by a descending film. Through the film a limiting gaseous reactant is transferred from the stagnant gas phase to the catalyst where the chemical reaction takes place.

摘要:

A quantitative study of the axial and tangential components of the mean velocity in a 3″-hydrocyclone using laser doppler anemometry has revealed multiple reverse flows in the vortex core. Flow visualization by dye injection shows that these flows are coherent over a significant portion of the hydrocyclone and that little radial mixing occurs between these secondary flows and the outer helical flow. A 2:1 contraction in the vortex finder plays an important role in causing four distinct simultaneous countercurrent flows in the conical section of the hydrocyclone.
