Process for cleaning of waste materials by refining and/or elimination of biologically Difficult to degrade halogen-, nitrogen- and/or sulfur compounds. |
摘要 |
<p>Liquid waste materials, contaminated with biologically difficult to degrade halogen, nitrogen and/or sulfur containing compounds and containing 0.1-60 WT.% halogen up to 10 WT% sulfur and/or small amounts of nitrogen, are cleaned or purified by conditioning these materials and passing them together with hydrogen over a guard column filled with absorbent, preferably granular alumina, under a hydrogen pressure of 30-80 bar and with an LHSV of 0.5-2.5H<-><1> and subsequently passing the stream over a hydrogenating catalyst, preferably a catalyst comprising nickel or cobalt plus molybdenum supported on an inert carrier.
<??>The catalyst is preferably a sulfided catalyst.</p> |
