So, choose appropriate catalyst and other functional material, make heavy realize catalytic cracking or degradation, to reduce the irreversible restructuring content or change its molecular structure, reduce the high-viscosity oil viscosity, to a certain extent, can reduce yields to heavy viscous drilling, airtight gathering and transportation and processing of difficulty, this also is the current research hotspot. In order to seek excellent catalyst and other functional materials, literature and the previous research mainly concentrated in the experiment, but experiments takes a lot of human, material and financial resources, and the cycle is long. Considering the current for heavy drop from the theory research and less sticky catalyst, the subject will use density functional theory (DFT) method, using Gaussian03,Chem 3D software and electronic structure and chemical from the aspects of catalysts, or functional materials, reduce heavy hydrogen to achieve in heavy upon the possibility of glue.
The oil is composed mainly of hydrocarbon oxygen, nitrogen, and sulfur and organic compounds of three elements, and the most important oxygenated compounds are acids compounds. Hydrogen bonding effect between molecular interactions, resulting in the enhancement of heavy viscosity heighten. The following main with acetic acid, discusses the model of furan - contains the iron ions, the influence of catalyst for hydrogen realize the possibility of hydrogen weakened. |
