Development and Commercial Application of Resid Hydrotreating Technology RHT

The RHT technology is developed by Research histitute of Petroteum Processing (RIPP) for residuum hydrotreating in order In produce good quality RFCC feed. The advantages of the RHT series catalysts are presented in this article, based on the results of activity tests and a 9500 hours service life test in pilot plants and the assessment on a commercial application.     

Abrasive Water Jet Perforation—An Alternative Approach to Enhance Oil Production

This article investigates the mechanisms, the results of laboratory experiments, and the results of field tests on the abrasive water jet (AWJ) perforation for enhancing oil production. The mechanism investigation showed that the AWJ perforation is a two-stage process, the ductile casing erosion stage and the brittle rock penetration stage, and each stage follows different failure mechanisms. The laboratory AWJ-parameter experiments were conducted on pressure, flow rate, abrasive material, abrasive granule size, abrasive flow rate, ambient pressure, rock material, and exposure time. The field tests of 10 oil wells (11 runs) illustrated that the AWJ perforation depth could reach about 0.78 m with pump pressure of 45-60 MPa at different formations, while the location error was less than 0.1 m. The oil production rate comparison, before and after implement, showed the AWJ perforation technology can effectively and prominently enhance oil production.

北方民居经典——牟氏庄园

牟氏庄园，是中国规模最大、保存最完整的封建地主庄园，是国家级重点文物保护单位。 该建筑群坐落在胶东半岛的栖霞市区北端的古镇都村，占地2万多平方米，拥有房产5500多间。各院沿南北中轴线依次建大门、前庭、客厅、寝楼，北群房及东西厢房构成多进四合院，疏密相问，布局井然。建筑工艺精湛之极，雕刻砌凿各见风景，尤其石砌墙体，堪称中国一绝。该建筑群落规模恢弘，古朴壮观，集中国历史文化、建筑文化、民族文化之大成，可称北方民居经典之作。     

阿克苏河流域近期防洪规划及工程措施

新疆阿克苏河流域洪水危害比较严重，全流域有较大的河道防洪险工段50多处，主要集中在托什干河的阿合奇、上色来阿拉尔、联合渠龙口、空台、阿合雅、牙满苏，以及库玛拉克河、阿克苏河、塔里木河等处．河道洪水洪峰高，历时短，洪量小，并有突发性洪水，防洪规划的原则是以防为主，防治并重，全面规划和综合治理．近期河道防洪标准为20年一遇，一般防护工程防洪标准为5年一遇．河道防洪工程的结构形式，上游河段采用砌石混凝土结构，中游采用铅丝笼堆石和稍料三角架结构，下游及塔里木河采用混凝土井柱桩式的型式，以满足流砂游动性河床冲刷深的特点．     

Deactivation kinetics and modelling of coke removal under supercritical conditions for the example of ethylbenzene disproportionation

Deactivation kinetics and coke removal kinetics were derived from experimental studies on the disproportionation of ethylbenzene with a protonated Y-faujasite (Z-14) in a loop reactor under supercritical conditions. Derivation of the steady state kinetics of ethylbenzene disproportionation permitted determination of the catalyst activity. At small educt mole fractions of ethylbenzene, owing to the modest removal of coke the deactivation kinetics can be described by a power relationship. The rate of coke removal can be correlated with the activity and the deactivation rate of the catalyst.     

还原扩散法直接制造ZrNi合金粉末的研究

对以Ｃａ作还原剂ＺｒＯ粉末和Ｎｉ粉末作原料，用还原扩散法直接制造ＺｒＮｉ合金粉末的过程进行了研究分析，发现Ｃａ不令是ＺｒＯ２的还原剂，而且Ｎｉ的溶剂和载体，在合金形成过程中，Ｎｉ通过在液体Ｃａ中溶解和扩散，到达被还原出出来的金属Ｚｒ表面，并与Ｚｒ合金化形成ＺｒＮｉ合金因此Ｃａ的添加量是过程的关键因素。
