VERFAHREN ZUM ENTAGGLOMERIEREN UND ERNEUEREN DER OBERFLÄCHE EINES KATALYSATORS IN EINEM WIRBELBETT |
摘要 |
<p>A fluid bed catalyst which has lost activity or fluidization quality through agglomeration, contamination, or a physical or chemical change on the surface of the catalyst is deagglomerated and/or its surface re-exposed, by contacting the fluidized catalyst 2 with a high velocity gas (8) sufficient to cause multiple collisions among the catalyst particles and thereby deagglomerating the particles and/or abrading the surface of the particles to expose fresh catalyst. <IMAGE></p> |
