Fenton reaction which is involved in Fe 2+ and H 2 O 2 , was observed by H.J.H. Fenton over 120 years ago, can decomposed organic compounds into H 2 O and CO 2 by the production of oxidizing species. This reaction has been widely used in wastewater treatment, remediation of groundwater. However the mechanism of this reaction is still in discussion. Here, recent studies on the mechanism and kinetics of fenton reaction are summarized and discussed; suggestions are given in research in this field.

Multistep fast pyrolysis of magnesium chloride (MgCl₂)–impregnated biomass materials offers a promising way to obtain a value-added chemical-rich liquid product. In this work, cotton stalk with MgCl₂was pyrolyzed in a thermogravimetric analyzer and a fixed-bed reactor at 260°C. The feedstock characteristics, product distribution, and liquid-phase compositions were analyzed. The presence of MgCl₂ changed the product distributions and liquid-phase composition. Only two targeted chemicals were successfully collected for the purpose of chemical production. The effect of catalyst loading on pyrolysis behavior for furfural and acetic acid production was studied. The furfural and acetic acid contents in the water-free liquid phase were about 28 and 51 percent, respectively, whereas the MgCl₂ content was 18.54 percent.
