Abstract: A robot for pond desilting is provided, which includes a frame, a lead screw sliding table, and a suction pipe. An end of the frame is provided with a pressure-resistant cabin. A lead screw base is disposed on the lead screw sliding table. A rotary lead screw is disposed on the lead screw sliding table. The lead screw base is disposed on the rotary lead screw. Waterproof motors are disposed above the lead screw base, a pump body is disposed in the frame, and the suction pipe is disposed at an end of the pump body. When the robot is placed at the bottom of the pond, the motor inside the pressure-resistant cabin drives the power wheels to rotate, the power wheels drive the tracks to rotate around the power wheels, bearing wheels, and tension wheels, thereby driving the frame to move.

Abstract: The present invention provides an iron and steel smelting method, wherein separating the product of the catalytic dehydrogenation reaction on propane to obtain a mixed gas containing hydrogen, methane, and ethane; and mixing the mixed gas with water and/or CO2 as a catalytic conversion raw material, and producing synthesis gas by means of a catalytic conversion reaction, the synthesis gas being used for iron smelting, and electricity being used to provide energy for the catalytic conversion reaction. The method catalytic dehydrogenation of propane is combined with steam cracking, and unconverted propane is prepared into methane, ethane, etc. by means of steam cracking; synthesis gas is further obtained by means of reforming and component adjustment, and the synthesis gas is a good raw material for direct reduction of iron.

Abstract: The present invention provides a method of steam cracking using electricity to supply energy. This method is to provide energy for steam cracking reaction of a cracking raw material by electromagnetic induction with electricity; the cracking raw material comprises one or more of naphtha, cycloalkane and cycloolefin; wherein the cycloalkane is a C4-C8 cycloalkane, and the cycloolefin is a C4-C8 cycloolefin. The present invention utilizes electricity to provide energy for the steam cracking reaction through an electromagnetic coil, which is a new use of electricity and solve the current problem of excess electricity. Moreover, utilizing the electromagnetic coil to provide power can make the heat distribution in the furnace tube of the cracking furnace more uniform, and it is easier to control the reaction temperature and the progress of the reaction.

Abstract: An oral microemulsion of elemene is disclosed. The microemulsion is made of elemene, surfactant, cosurfactant and water or buffer solutions with pH 5˜8. Said surfactant is selected form tweens, polyoxyethylene castor oils, polyethylene glycol stearates and mixture thereof. Said cosurfactant is selected from ethanol, 1,3-propanediol, glycerol and mixture thereof. The concentration of elemene in the microemulsion is 1˜5 g/100 ml. The ratio of elemene, surfactant and cosurfactant is 1˜5(weight):1˜40(weight):1˜40(volume), wherein the unit of weight/volume is g/ml.
