Abstract:
     A process for preparing series hydrocarbon surfactants by modification of black liquid resin after paper-making include the reaction of or compounding C4-C38 paraffin, olefin, or aromatic hydrocarbon, one or several of alkyl and aromatic petroleum surfactants, with 20%-80% black liquid resin in alkaline aqueous solution under ordinary pressure and at 80-100 deg.C for 1-3 hours. The obtained hdyrocarbon surfactant may be effectively used in thick petroleum extraction, asphalt emulsification and the third extration of petroleum to greatly reduce viscosity of petroleum with a reduction rate of up to 97-98%.
