Heavy or extra-heavy oil is hard to transport through pipeline because of its high viscosity and density. To reduce its viscosity and density, in situ partial upgrading process is required. For using a catalyst of RTP which is one of the upgrading processes, iron nanoparticles were synthesized by using W/O microemulsion with water/n-butanol/CTAB/n-octane. Synthesized nanoparticles had relatively uniform size (~10nm) and shape. Also, they have superparamagnetism, which can be used for recovery of them after cracking reaction. By XRD, it was verified that these nanoparticles are composed of iron, and their TEM images showed that they have spherical shapes and about 10nm diameters. The synthesized iron nanoparticles were added to RTP(Rapid thermal pyrolysis) reactor as catalyst. In comparison to liquid products without catalyst, liquid yield were similar. API degrees of liquid products with catalyst are higher than those without catalyst. |
