Asphaltenes : Chemical Transformation During Hy... Page

The nature of these transformations is highly dependent on temperature and the presence of catalysts.

Nickel and vanadium also tend to concentrate in the remaining asphaltene structures as lighter components are cracked away. Impact of Reaction Conditions Asphaltenes : chemical transformation during hy...

Resistant to removal; it often concentrates in the asphaltene fraction during processing, sometimes leading to an overall increase in nitrogen content. The nature of these transformations is highly dependent
