Bimetallic supported catalysts for hydrocarbons and alcohols reforming reactions
This chapter gives a brief resume of the state of the art on bimetallic catalysts for the reforming of hydrocarbons and alcohols. As part of hydrogen production technologies, reforming is the most widely used process, thanks to its low cost and mature technology. The bimetallic catalysts show an improvement in activity, selectivity, and stability with respect to the monometallic systems; their use allows to design systems with unique characteristics, totally different from those of monometallic catalysts. The most diffused reforming technology concerns methane conversion and is mainly used in industrial processes for the production of ammonia, methanol, and the C5-C12 hydrocarbon fractions. However, the reforming of nonfossil sources is the fastest growing research field, due to the renewability and low environmental impact. This chapter is divided into three main sections, reforming of methane, hydrocarbons, and alcohols, which are focused on the description of the main bimetallic catalyst systems, reaction mechanisms proposed and, where possible, comparisons on the performance.
