Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

EFFECTS OF MATERIAL CHARACTERISTICS ON PERFORMANCE OF HYDROCRACKING CATALYSTS

Journal of the Turkish Chemical Society Section B: Chemical Engineering, 2017
Hydrocracking is a refinery process used to convert heavy hydrocarbon fractions to lighter cuts with high added value. The products that usually range from heavy diesel to light naphtha involving middle distillate as targeted cut are obtained as a result
