摘要：截至2016年3月1日,陕西省首个甲醇制芳烃（MTA）项目——陕西宝氮化工集团新建的10万t/a甲醇制芳烃项目已平稳运行45 d,目前日产芳烃300 t,接近设计负荷。据了解,该项固定床绝热反应器一步法甲醇转化制芳烃技术甲醇制芳烃,和国外开发的同类技术相比,省略了用于甲醇制二甲醚的反应器及其催化剂,设备投资强度降低,生产过程控制更为简单合理。

摘要：由于有的家庭厨房小,且摆放的东西较多,厨房显得比较拥挤,致使液化石油气钢瓶倾斜放置或者卧放.这是很危险的。 液化石油气,顾名思义是液态的。在液化石油气钢瓶正常放置时,即使是满瓶,液体也只占钢瓶容积的85％.所以瓶的上部仍是空的。但不是真空的,而是充满丁烷、丁烯、丙烷、丙烯等的混合气。

摘要：Water tightness and seepage control are important considerations in the design and construction of dams. Plastic concrete cut-off walls are one of the effective means for seepage control in earth dams constructed on permeable substrate. An important requirement for the plastic concrete in such applications is adequate strength for the design loads and low enough permeability to meet the water tightness requirements of the dam. As permeability of cement-based materials, such as concrete, is mainly dependent on water to cement ratio, the permeability of plastic concretes is much higher than those of normal concretes. It is thus apparent that the achieving to low permeability is an important problem in plastic concrete. So a method, which could reduce the permeability of plastic concretes without unduly increasing their elastic modulus, would provide considerable technical advantages. In the present research, the possibility of lowering the permeability of plastic concrete thorough replacement of a portion of cement by micro silica was investigated. The aim of the experimental research was to investigate the effects of various levels of cement replacement by micro silica, including 0%, 3%, 6%, 9%, 12% and 15% on strength and permeability of plastic concrete. The results illustrate that the use of micro silica for replacement of some of the cement content in plastic concrete results in very substantial decrease in permeability. Obtained results show that through the use of micro silica in plastic concrete, it is possible to keep the strength and elastic modulus at the level of control mix and still achieve to reduction in permeability.
