Influence of reaction temperature, pressure and space velocity on the direct synthesis of dimethyl ether (DME) from syngas is studied in an isothermal fixed-bed reactor. The catalyst is a physical mixture of C301 copper-based methanol (MeOH) synthesis catalyst and ZSM-5 dehydration catalyst. The experimental results show that the chemical synergy between methanol synthesis reaction and methanol dehydration reaction is evident. The conversion of carbon monoxide is over 90%.

作者： McMasters, O.D. ETREMA products inc Ames United States

The development of the giant magnetostrictive rare earth-iron materials is reported from their discovery in the early 1970's to their present use in transducer and sensor applications. Fifteen broad market areas, ranging from miniature devices in the medical industry to high powder sonar and seismic sources have been identified. A world-wide customer base in these high technology fields has been established and the superior properties of these materials are responsible for the rapid growth of the magnetostrictive transducer industries. The critical design criteria that lead to efficient devices are reported and the performance of several of these products is presented. The key patents associated with these giant magnetostrictive materials and devices using these materials are reviewed. The present and future of these technologies in reference to commercialization, market growth and the impact on the many transduction industries are discussed. (Author abstract) 9 Refs.

Convergence of roof and floor in underground mine openings is a common occurrence. This convergence not only adversely affects the ability of workers, equipment and supplies to travel through the mine, it also reduces the effectiveness of the mine ventilation system, which is essential for the dilution of methane gas and airborne respirable dust. While installing secondary standing supports to control floor and roof convergence, such supports, by nature, partially obstruct a portion of the airway. These added obstructions inhibit the ability of the ventilation system to operate as efficiently as it could by inc.easing the resistance in and reducing the cross-sectional area of the airway. This study introduces and demonstrates the benefits of The Eye CAN^(TM) standing roof support, which controls floor and roof convergence and is less obstructive to air flow than conventional wooden cribs. Laboratory findings show that the normal resistance of a supported lined airway is reduced by using this new product from Burrell Mining products, inc., while providing the same roof support characteristics of an established product—The CANò. Load vs. displacement curves generated from laboratory tests demonstrated that this new product behaves with the same roof support characteristics as others in The CAN product family. Ventilation data gathered from a simulated mine entry was then used for computational fluid dynamics(CFD) *** CFD analysis showed an improvement with The Eye CAN vs. other accepted forms of standing roof support. This proof-of-concept study suggests that, when using this new product made by Burrell Mining products, inc., not only will the convergence from the roof and floor be controlled, but airway resistance will also be reduced.

热喷涂技术已被广泛用于制备金属表面保护涂层,其特点是可直接喷涂熔融态或加热的金属前驱体。涂层材料通常是由等离子体或氧燃料燃烧装置加热。在喷涂过程中,基体温度需冷却并精确控制,以避免由于过热而引发的涂层质量问题。本文开发了一种低温氮气基冷却液,其可直接冷却正在进行喷涂的基体部位,避免传统空冷方式下涂层间隙中存在的冷却间歇(等待基体被喷涂部位冷却),进而提高喷涂效率。该系统不仅可以冷却工件,还可通过红外传感器和闭环控制方案将工件温度控制在指定范围。实验表明,热喷涂冷却可将工艺时间大幅减少50%,并提高沉积效率,同时,还可实现更严格的温度控制(±20°F),更小的微孔隙率密度(0.05%),更高的基材硬度,更少的涂层氧化或碳损失,并使涂层中的残余应力最小化。
