Systematically analyzing the problem of heavy metals in the municipal sludge, a meta-analysis of nine metals was undertaken to distinguish the sources and sinks of those with the impact of their accumulation on the environment. Municipal sludge was rich in N, P and K nutrients, was found to...

The paper reports partial oxidative gasification of phenol for hydrogen in supercritical water (SCW) at lower temperature (753 K), at which cleavages of aromatic ring occur difficultly and tend to undesirable polymerization. The results showed that O2 is effective to gasification of phenol in...

Bifunctional Fe/ZrO2 was prepared by mechanical mixing method, and its bifunctional effect on reductive dechlorination of chlorobenzene in subcritical water was studied. Dechlorination efficiency increased with increasing iron content in catalyst and catalyst amount. Dechlorination efficiency...
