摘要
Cis-9-Octadecenylamine modified α-Fe 2 O 3 and Fe(OH) 3 nanoparticles were successfully synthesized by using a one-step synthetic method. XRD results revealed that lower ratio of oleylamine to Fe 3+ introduce forming hematite phase but higher ratio introduce forming Fe(OH) 3 phase. FTIR, TGA, contact angle, and XPS results indicated that olelyamine were modified on the surface of α-Fe 2 O 3 or Fe(OH) 3 . A larger amount of oleylamine modifier is conducive to the dispersion of the catalysts in heavy oil. Oleylamine modified Fe(OH) 3 can be transformed into α-Fe 2 O 3 in situ during the catalytic reaction and shows higher catalytic activity in the viscosity reduction of Shengli extra heavy crude oil.
