Green Needle Coke Production from Pyrolysis Biocrude toward Bio-based Anode Material Manufacture: Biochar Fines Addition Effect as “Physical Template” on the Crystalline Order

Eliezer A. Reyes Molina, Trevor Vook, William Joe Sagues, Keonhee Kim et autres

A new method for producing green needle coke (GNC) is developed by replacing the “heavy fraction” of petroleum pitch delayed coking with fast pyrolysis biocrude. A series of alternative biocrude distillation, carbonization, and calcination conditions were investigated to determine the influence of …

Foamability of non-aqueous systems containing asphaltenes from a heavy crude oil

Eliezer A. Reyes Molina, José G. Delgado‐Linares, Antonio L. Cárdenas, Ana Forgiarini

Non-aqueous foams are much less studied than aqueous foam systems, although non-aqueous foams are important in many industries like petroleum refining. In this study, the foamability of non-aqueous systems consisting of toluene, paraffin, and asphaltenes was tested. It was found that the …
