    • A process for the selective hydrogenation of dienes and acetylenes in a mixed hydrocarbon stream from a pyrolysis steam cracker in which a front end a one step acetylene hydrogenation is carried out using catalyst comprising (A) 1 to 30 wt. % based on the total weight of the catalyst of a catalytic component of nickel only or nickel and one or more elements selected from the group consisting of copper, rhenium, palladium, zinc, gold, silver, magnesium, molybdenum, calcium and bismuth deposited on (B) a support having the a BET surface area of from 1 to about 100 m2/gram, total nitrogen pore volume of from 0.2 to about 0.9 cc/gram and an average pore diameter of from about 110 to 450 Å under conditions of temperature and pressure to selectively hydrogenate acetylenes and dienes. The process hydrogenates the dienes and acetylenes to olefins without loss of ethylene and propylene in the light and heavy products which eliminates the need for further processing of the heavier stream. In addition the amount of polymerization in the lower part of the distillation column reactor is reduced.
    • 在来自热解蒸汽裂化器的混合烃流中二烯和乙炔的选择性加氢的方法,其中前端使用包含(A)1-30重量%的催化剂进行一步乙炔氢化。 基于仅镍或镍的催化组分的催化剂的总重量和选自铜,铼,钯,锌,金,银,镁,钼,钙和铋的一种或多种元素的% (B)具有1至约100m 2 / g的BET表面积,0.2至约0.9cc / g的总氮孔体积和约110至450的平均孔径的载体在温度条件下 以及选择性氢化炔烃和二烯烃的压力。 该方法将二烯和乙炔氢化成烯烃,而在轻质和重质产物中不损失乙烯和丙烯,这消除了对较重物流的进一步加工的需要。 此外,蒸馏塔反应器下部的聚合量降低。

    • A new approach is disclosed for measuring the pressure of tight gas reservoirs, using information obtain from continuous injection prior to hydraulic fracture stimulation. The technique can be obtained utilizing either bottom-hole or surface pressure gauges and properly instrumented surface injection pumps. The analysis is completed by plotting injection and rate data in a specialized form from terms arranged in Darcy's radial flow equation to obtain a curve or trend. The key component to proper application of this technique is to obtain both baseline and one or more calibration data sets. These calibration data sets are obtained by either increasing or decreasing the injection pressure and/or rate from the baseline data. Initial reservoir pressure is assumed, but the calibration data indicates if the guess was too high or low. Accurate estimates of reservoir pressure may be obtained in a few iterations.
    • 公开了一种新的方法来测量紧密气藏的压力,使用在水力压裂刺激之前从连续注射获得的信息。 该技术可以利用底孔或表面压力表和适当仪表的表面注射泵来获得。 通过以Darcy的径向流方程式排列的术语以专门的形式绘制注射和速率数据,以获得曲线或趋势,从而完成分析。 正确应用该技术的关键部分是获得基线和一个或多个校准数据集。 这些校准数据集是通过从基线数据增加或减少注入压力和/或速率获得的。 假设初始储层压力,但校准数据表明猜测是否过高或过低。 油藏压力的准确估计可以在几次迭代中获得。
