Anti-Strip Additive for Bitumen by Processing Lignin

Abstract:

The study was directed toward modifying of lignin by applying processes of depolymerization alkylation and propoxylation to obtain anti-strip additives for bitumen. Lignin depolymerization was carried out by catalytic hydrotreating on catalyst W-Mo/Al2O3, in continuous system and a fixed bed of catalyst. Dispersant characteristics of phenols obtained by lignin depolymerization where improved by increasing the content of hydrophobic groups and of hydrophilic groups, changes made through alkylation and propoxylation of this phenols. Alkylation of cresols was performed in a batch system in the presence of a catalyst phosphotungstic acid supported on mesoporous silica and propoxylation was performed in a batch system in the presence of KOH catalyst. Heterogenous catalysts characterization where performed by determining the acid strength and textural characteristics. The adhesiveness of bitumen is improved by addition of depolymerized-alkylated-propoxylated lignin.
