Kerosene oxidation rate

Oxidation of kerosene (fuel oil no. 1) and diesel fuel (fuel oil no. 2) by soil microbes, as determined by dehydrogenase activity, increased with increasing loading rates for both fuel oils (up to 60% w/w oil/dry soil) for up to 7 days of incubation but decreased thereafter. Dehydrogenase activity in soil treated with diesel fuel was almost twice that of soils treated with kerosene (56 and 32 g formazan/g soil/24 hours, respectively) (Frankenberger and Johanson 1982). 

Dispersions are finely divided particles suspended in some liquid, often flammable, to inhibit oxidation, reaction with moisture, or to accurately control reaction rates e.g., sodium may be dispersed in toluene, xylene, naphtha, or kerosene.
