Quan, Hongping published the artcileThe effect of hydrogen bonds between flow improvers with asphaltene for heavy crude oil, Recommanded Product: Dodecyl 2-methylacrylate, the main research area is asphaltene heavy crude oil hydrogen bond flow improver.
A series of chem. products with characteristic groups in mol. structures were synthesized as novel flow improvers (FIs) for heavy asphaltenic crude oil. The rheol. measurement results showed that the FI-5 could behave the better performance in improving fluidity of heavy oil than FI-2 due to the former could form stronger hydrogen bonds with asphaltene in oil, which was confirmed through Fourier transform IR spectroscopy (FTIR) and energy of simulating studies. Furthermore, X-ray diffraction (XRD) anal. results demonstrated that two products altered asphaltene structure at different degree through hydrogen bonding interaction, and the aggregation-dispersion effect of FIs on asphaltene were resp. obtained through scanning electron microscope (SEM), which beneficially weakened the stable structure of asphaltene in the heavy crude oil system. Hence, the mechanisms were tried to propose that could explain the phenomenon in rheol. measurement why FI-2 was not as good as FI-5 in improving fluidity of heavy oil. Results also indicated that the asphaltene content and aggregation structure in oils were vital parameters for its viscosity.
