摘要： Disclosed is a method for increasing the yield of a slurry bed reactor. The method provides a slurry bed reactor with a recycling unit or a replacing unit. An absorbing agent is fed into the slurry bed reactor. The absorbing agent is a substance that can react with at least one product of a primary reaction or at least one reactant of a side reaction. Then, the absorbing agent is transmitted into the recycling unit or the replacing unit. The recycling unit renews the absorbing agent and sends the renewed absorbing agent back into the slurry bed reactor for reuse. The replacing unit replaces the absorbing agent with new absorbing agent and sends the new absorbing agent into the slurry bed reactor for use.

摘要： Disclosed is a method for making dimethyl ether by reactive distillation. The method provides a reactive distillation tower with a top, a bottom, and rectification, reaction and stripping zones defined therein. The top of the reactive distillation tower is retained at 25° C. to 40° C. while the bottom of the reactive distillation tower is retained at 84.6° C. to 170° C. Each of the rectification, reaction and stripping zones includes several sieving trays. The reaction zone of the reactive distillation tower is filled with catalyst. The pressure in the reactive distillation tower is lower than 8.0 bars. Methanol is introduced into the reactive distillation tower so that the methanol travels from the reaction zone toward the bottom for contact with the catalyst to provide a top stream and a bottom stream. The top stream includes dimethyl ether. The bottom stream includes water and a remaining portion of the methanol. Finally, the dimethyl ether is collected in the top of the reactive distillation tower. The purity of the collected dimethyl ether is higher than 99%.

摘要： The present invention provides a plasma torch device. The device comprises a front electrode, a back electrode and a vortex flow generator. The torch roots of the back electrode are moved by fixed magnets. By controlling the magnets coordinated with vortex air flow, the torch roots are moved back and forth periodically on inner surface of the back electrode. The torch roots do not stay at the same place for long for preventing increasing local heat burden of the electrode. Thus, life time and maintenance cycle of the electrode is prolonged with reduced operational cost of plasma torch and enhanced reliability of the device.
摘要翻译： 本发明提供一种等离子体焰炬装置。 该装置包括前电极，背电极和涡流发生器。 背面电极的割炬根由固定磁铁移动。 通过控制与涡流空气流动协调的磁体，焊炬根部在后电极的内表面周期性地前后移动。 手电根不会长时间停留在同一处，以防止电极的局部热负荷增加。 因此，延长了电极的寿命和维护周期，降低了等离子体焰炬的运行成本，提高了设备的可靠性。
