Water-in-oil (W/O) emulsions create many processing problems in petroleum industry. The enhanced stability of droplets and poor separation of emulsions are often associated with the interfacial accumulation of asphaltenes. The complex nature of asphaltenes has complicated the understanding of...
Suppression of addition reactions of asphaltene model compound during hydrogenation with sulfided iron catalystDownload
A model compound is used to probe the chemical and physical behaviors of asphaltene. Hydrogenation reactions were conducted in a batch microreactor at 430℃, 13.9 MPa H2 for 30 min using a solution of 1,3,6,8-tetrahexylpyrene in tetralin. Sulfided iron was prepared on α-alumina, γ-alumina and...
