国内外微生物采油技术综述

生物技术特别是微生物采油技术，已经引起了石油工程技术人员的空前关注，目前在国内外开展的微生物采油先导性矿场试验已初见成效，较为典型的当数美国和俄罗斯，我国的吉林、胜利等油田也进行了矿场试验，增油效果令人鼓舞。同时，随着科学技术的发展，一些先进的微生物学研究工具已经进入微生物采油技术的研究领域，如分子生物学、示踪剂及可视化技术等已经成为微生物采油机理研究的重要工具。相关的石油烃降解理论以及建立数学模型等也取得了系列成果。微生物采油的应用也从过去的单井处理逐渐向整个区块或油田发展，并见到了明显效果。

Behavioral Phenotype of the Reeler Mutant Mouse: Effects of Reln Gene Dosage and Social Isolation.

Reeler (rl/rl) and reeler/wild-type (+/rl) mice synthesize Reln at subnormal rates, as do patients with schizophrenia, bipolar disorder, and autism, thereby forming the basis for a Reln hypothesis for vulnerability to these psychopathologies and justifying attention to the behavioral phenotypes of Reln-deficient mice. Tests of gait, emotionality, social aggression, spatial working memory, novel-object detection, fear conditioning, and sensorimotor reflex modulation revealed the behavioral phenotype of rl/rl, but not +/rl, mice to be different from that of wild-type (+/+) mice. These results reveal no effect of Reln gene dosage and provide significant challenges to both the Reln and the neurodevelopmental hypotheses of the etiology of major psychopathologies.

天然气脱除Ｈ２Ｓ和ＣＯ２是天然气净化领域经常遇到的问题。Ｈ２Ｓ与醇胺的反应属瞬间质子反应，ＣＯ２与醇胺的反应则复杂得多，醇胺溶液对Ｈ２Ｓ的选择性分离主要依靠ＣＯ２与醇胺的反应速度差异来实现。文章介绍了伯胺，仲胺，叔胺及空间位阻胺溶液反应的机理和动力学。     

Relationship between CO2 Sensor Voltage Response and Phase Equilibrium of Solid Electrolyte Na, K-β/β"-Al2O3

A type of CO2 sensor based on oxygen concentration cell was designed as following: Cell I: Pt | Au, O2,CO2|Na2CO3(Au)|NKBA(Au)|YSZ|O2, CO2|Pt or Cell Ⅱ: Pt|Au, O2, CO2|K2CO3(Au)|NKBA(Au)|YSZ|O2, CO2|Pt.(Na,K-β/β″-Al2O3 is named by NKBA). The sensor signal is consistent with the Nernstian slope within the region ofphase equilibrium for Na, K-β/β"-Al2O3 material. The relationship between CO2 sensor voltage response and phaseequilibrium of solid electrolyte Na, K-β/β-Al2O3 is discussed in this paper.

高能气体压裂过程中CO气体浓度扩散规律

针对低渗透油气田在高能气体压裂增产措施中CO气体中毒事件,运用现场数据和数学模拟方法通过对CO气体流动、扩散等的综合研究,建立了CO井筒流动及大气扩散模型。同时,也考察了井筒压力、气油比、大气稳定度等主要因素对CO气体扩散的影响。通过现场实例计算,证实模型具有较高的准确性,对合理、有效地开发油气田及煤层气的开发具有重要的实际意义。     

A kinetic investigation into the removal of carbobenzyloxy group from protected amines via hydrogenolysis reaction

Hydrogenolysis of a carbobenzyloxy group (CBz) was studied utilizing molecular hydrogen in the presence of carbon-supported palladium catalyst. It was demonstrated that the kinetics of the reaction are greatly influenced by the presence of the CO₂ by-product. It was found out that the presence of CO₂ determines whether the reaction is first or zero order since it causes deactivation of the catalyst via inhibition. The effect of potassium carbonate (K₂CO₃) and triethylamine (TEA) as additives was investigated. A considerable solvent effect was also observed that may be explained by the variation of dispersion of the catalyst from one solvent to another.
