Hydroprocessing of fuels can help
meeting the demands of the market in terms of refining heavier (more
refractory) feeds while manufacturing products with enhanced quality [1]; higher H:C ratio, lower
molecular weight and less aromatic-heteroatom molecules. For severe
hydroprocessing (hydrocracking), a bifunctional catalyst is used [2] in order to yield products of
hydrogenation-hydrogolysis (on the metallic sites) and cracking (on the acidic
sites). Although the mechanisms of reaction hydrocarbon- hydrogen on the
metallic sites have been extensible studied [3-5], the analogous
ones on the acidic sites (with hydrogen) remains less well understood. In this
work we have studied the hydroconversion of a cycloalkane (methylcycloalkane)
on a zeolite HZSM-5 in
hydrocracking conditions as a model reaction. Tracing reaction products and their
ratios enable us to state the condition at which certain mechanisms dominate so
that enhanced product distributions can be obtained.
