因此，選用適當催化劑和其他功能材料，使稠油實現(xiàn)催化裂解或降解，不可逆地降低重組分含量或改變其分子結(jié)構(gòu)，降低稠油黏度，在一定程度上使稠油輕質(zhì)化，可以降低稠油開采、集輸和加工難度，這也是當前研究的熱點之一。為了尋求優(yōu)良的催化劑和其他功能材料，先前主要的文獻和研究集中在實驗方面，但實驗需要耗費大量人力、物力、財力，且周期較長�？紤]到目前從對于稠油降黏催化劑的理論研究較少，本課題將利用密度泛函理論（DFT）計算方法，利用Gaussian03軟件包，結(jié)合Chem 3D等軟件，從電子結(jié)構(gòu)和化學鍵方面，探討應用催化劑或功能材料降低稠油中氫鍵，以達到稠油降黏的可能性。 石油中的非烴組成主要是含氧、氮和硫等三種元素的有機化合物，而最重要的含氧化合物是酸類化合物。氫鍵的作用使得分子間相互作用力增強，從而導致稠油粘稠度增高。以下主要以乙酸-呋喃為模型，探討含鐵離子催化劑對氫鍵的影響，實現(xiàn)削弱氫鍵的可能性。 |

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. |
