The invention belongs to the technical field of catalyst materials and
hydrogen energy, and relates to a preparation method of a
platinum-
ruthenium bimetallic catalyst and an application method of the
platinum-
ruthenium bimetallic catalyst in hydrogenation of an organic
hydrogen carrier. According to the technical scheme, the bimetallic catalyst contains a carrier and an active
metal component, the carrier is porous
alumina or other carriers, and the active
metal component is a mixture of
platinum and
ruthenium components. The preparation method of the catalyst is an impregnation method, and comprises the following steps: preparing an
alumina carrier, impregnating a
metal precursor,
roasting after impregnation, and carrying out
reduction treatment. The invention also provides a process method for applying the catalyst to
hydrogenation reaction of the organic
hydrogen carrier. The process method comprises the following steps: adding the catalyst and the organic
hydrogen carrier into a reaction container of a reaction kettle by adopting a kettle type reactor; the organic
hydrogen carrier is benzyl
toluene, dibenzyl
toluene and the like. The preparation method of the platinum-ruthenium bimetallic catalyst, provided by the invention, has relatively high universality, is particularly suitable for the hydrogenation field of organic hydrogen carriers, and is beneficial to promoting the development of the technical field of hydrogen energy.
