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. [1] 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. [2] 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. [3] The relationship between the metal site and the acid site will be studied in further detail.
