  • Patent number: 10709005
    Abstract: Plasma torch with an integrated electrode incorporating many heat pipes each heat pipe comprises an evaporating section and a condensing section set at a front end and a rear end of the electrode, respectively. The heat pipes with extremely high thermal conductivity can be used to replace the traditional water-cooled torch's electrode. The effect of reducing the elevated temperature at the torch's arc root zone through cooling by heat pipes is beneficial for prolonging the lifetime of plasma torch. Each heat pipe is filled with a small amount of working fluid. Even if one heat pipe is etched out, the cooling liquid thus ejected is limited without causing gas explosion and rock curing; the rest of heat pipes are not damage and can still function; although the heat dissipation efficiency might be reduced a little, the plasma torch still works. Thus, flexibility of the whole heat dissipation is enhanced.

  • Patent number: 10302379
    Abstract: An apparatus is provided for detecting the quality of a heat pipe. The apparatus has an infrared (IR) thermal imager bound with a data computing-and-analyzing program to detect thermal conductivity quality and vacuum quality of the heat pipe. An online overall detection is thus provided to quickly detect the quality of the heat pipe without damage for efficient quality control. Requirements of quality detection are met for mass production of heat pipes. The apparatus comprises the heat pipe to be tested; a tape adhered to a surface of the heat pipe; a fixed base for disposing the heat pipe; a heating device in an allocation space of the fixed base; the IR thermal imager located facing to the tape; a signal line connected to the IR thermal imager; and an electronic device connected to the IR thermal imager through the signal line.

  • Publication number: 20160362355
    Abstract: An oil product of gasoline is fabricated. The product contains hydrocarbon compound ranged as a gasoline composition. The purification process of dimethyl ether (DME) used in the present invention greatly reduces the feed rate for obtaining a smaller reactor with cost down. Carbon dioxide (CO2) is separated to be recycled back to the gasifier to be reused, archived or used otherwise for improves global environment. At the same time, CO2 is reacted with hydrocarbons, water vapor, etc. through a novel high-temperature plasma torch to generate a synthesis gas (syngas) of carbon monoxide (CO) and hydrogen (H2) for regulating a hydrogen/carbon ratio of a biomass- or hydrocarbon-synthesized compound and helping subsequent chemical synthesis reactions. In the end, the final gasoline production has a high yield, a high octane rate, low nitrogen and sulfur pollution and a highly ‘green’ quality.

  • Patent number: 8816134
    Abstract: 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.

  • Publication number: 20140070533
    Abstract: A fast heat transfer device is provided. The device dissipates heat and generates power at the same time. A liquid flow is used to absorb heat for forming a vapor gas flow; then, the gas flow drives a blade turbine and a power generator; and, finally, the gas flow is cooled down to become the original liquid flow for recycling. Thus, the present invention dissipates heat and generates power simultaneously with a minimized size and a reduced cost together with energy conservation.

  • Patent number: 8440728
    Abstract: 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.

  • Publication number: 20110294654
    Abstract: A method for making a catalyst is provided. A plasma treatment is inserted between drying process and calcination process. By using a plasma, not only the species and materials in the gas-phase can reacted and inserted into the catalyst, but also the species and materials on the catalyst surface can be modified and removed from the catalyst. The plasma process can thus alter catalyst characteristics, increase products' selectivity, and enhance catalytic activity.
