ABSTRACT
Metals and metal oxides, as a rule, accelerate the liquid-phase oxidation of hydrocarbons.
This acceleration is produced by the initiation of free radicals via catalytic decomposition of
hydroperoxides or catalysis of the reaction of RH with dioxygen (see Chapter 10). In addition
to the catalytic action, a solid powder of different compounds gives evidence of the inhibiting
action [1-3]. Here are a few examples. The following metals in the form of a powder retard the
autoxidation of a hydrocarbon mixture (fuel T-6, at T¼ 398 K): Mg, Mo, Ni, Nb V, W, and Zn [4,5]. The retarding action of the following compounds was described in the literature.
