Bifunctional metal-acid catalysts for selective hydrocarbon conversion
In the petroleum industry, one of the key reaction is the hydroisomerisation of linear alkanes into branched alkanes products that have a higher octane value and are therefore more valuable.  This reaction is typically performed involving a bifunctional catalyst including a metallic site and an acid site. The intimacy criterion between this two actives sites is a critical parameter for activity and selectivity.  Although it was generally admitted that a close proximity was required, it has been shown recently, that a nanoscale proximity between the two type of active sites can be detrimental for the selectivity.  The relationship between the metal site and the acid site will be studied in further detail.
