Abstract
The present disclosure covers the use of polymers or copolymers having a naphthalene-type unit in their structure as heterogeneous hydrogen transfer agents for hydrogenation, hydrotreatment or reduction reactions. These heterogeneous hydrogen transfer agents may or may not be supported on metallic oxides and may be used in the presence of reducing agents such as hydrogen or methane. These hydrogen donors, being solid at the reaction temperature, may be recovered from the reaction mixture and reused, and are thermally and chemically stable at temperatures up to above 450° C.
