隔膜中残油量对锂电池性能的影响

锂离子电池隔膜在锂离子电池中主要起隔绝正负极防止短路和允许锂离子导通的作用[1],因此,锂离子电池隔膜品质的优劣直接影响到锂离子电池的应用性能。在锂电池隔膜制备的过程中,以石蜡油作为造孔剂,用热致相分离法制备聚乙烯微孔膜,石蜡油的残留不可避免。本文研究了隔膜中石蜡油的残留量对电池自放电、倍率放电、高温存储、循环性能等应用性能的影响。研究结果表明,残油量越低锂电池的应用性能越优。     

生物地耕法降解含油污泥的研究

Remaining oil distribution in Ng3^3 bottom water reservoir of Lin 2-6 fault-block in Huimin depression and potential tapping in horizontal well

Oil reservoirs with secondary bottom water in Ng33 members (in Guantao formation, Paleogene system) of Lin2-6 fault block in Huimin depression (Bohai Bay Basin) have entered the late stage of ultra-high water-containing-exploitation. Oil exploita-tion from vertical wells is becoming more and more inefficient. The reservoir type, with water displacing oil and the remaining oil distribution are specifically studied in order to improve the efficiency of the recovery ratio. An integrated scheme for adjusting horizontal wells has been designed and the key technique of the scheme optimized. The study shows that: 1) the positive rhythm of fluvial depositional features is the internal cause of the flooding of oil reservoirs while water injection, injection-production patterns and accumulative petroleum production are the external causes; 2) oil-water driving patterns have transferred from edge water ad-vancing to bottom-water-coning; distribution of the remaining oil mainly concentrates in the upper rhythm and top of the middle rhythm in Ng33 members; 3) a great deal of remaining oil is enriched in high positions of faults, in axes of tiny structures, in stagna-tion areas among water-injection wells and oil-wells and in tectonic saddle areas with sparse wells. Compared with vertical wells, horizontal wells have advantages such as high recovery, high off-take potential, high critical output, large controlling areas and long time of bottom-water breakthrough.

R＆D and Application of Catalyst for Resid Hydrotreating in Upflow Reactor

In order to extend the operating cycle of the upflow reactor for resid hydrotreating, the Research Institute of Petroleum Processing taking into account the specifics of resid hydrotreating upflow reactor has developed the high-performance RUF series of catalysts suitable for operation in the upflow reactor. The results of commercial application of catalysts revealed that this RUF series of catalysts loaded after optimized grading could effectively remove metals, sulfur and carbon residue from the residuum to provide improved oil for the following fixed-bed reactor. In the meantime, the RUF series of catalysts have excellent stability to reach an operating cycle of 1.5 years, resulting in minimization of losses caused by refinery downtime.
