The invention provides a preparation method which is simple and easy to operate and is used for loading an MOFs (Metal-organic Frameworks) material on a big-pore tubular carrier to prepare a continuous and compact non-crack MOFs thin film, and solves the difficult problems that the MOFs material has few nucleation sites on the surface of the organic carrier and is difficult to form the film, particularly, the MOFs material has a large defect on the surface of the big-pore carrier and a pure chemical method cannot achieve the effect of uniformly modifying.

Damage to a gallium arsenide substrate during plasma ignition for PVD processing is avoided by a virtual shutter, which provides the functions without the disadvantages of a mechanical shutter to minimize the density of high energy particles created during plasma ignition from reaching the GaAs substrate. A plasma ignition process sequence uses a high pressure gas ignition gas burst in combination with the control of other parameters, such as (a) varying the plasma ignition gas composition to include xenon, krypton or fluorinated molecular gases, (b) varying target-to-substrate distance to at least double the distance during plasma ignition, (c) increasing the magnetron magnetic field strength either permanently or during plasma ignition to about 400 Gauss, (d) preconditioning the target by sputtering whenever the system has been idle for several minutes, (e) adjusting the power supply power ramping to the target over 5-6 seconds or more, and/or (f) using a simple electric circuit to drain charge build up on the GaAs substrate.

The invention relates to a method for removing tar and coke during gasification and a method and a device for reforming combustible gas. The method is characterized in that: pyrolytic gasified gas is fed into a porous ceramic superadiabatic partial tar and coke oxidizing and removing device, and undergoes partial combustion at the front end of porous ceramics or inside a ceramic body; high temperature generated by the combustion carries out heat storage of a porous ceramic body; during the process, the tar inside a combustible gas undergoes pyrolysis in the superadiabatic environment of the porous ceramics so as to form small molecular gas, while alkane gas components inside the combustible gas undergo reforming reaction inside the porous ceramics; and the coke is completely oxidized inside the porous ceramics, thereby reaching the goal of removing the coke. The methods and the device have the advantages that: the tar and the coke are not attached to the porous ceramics or the surface of porous ceramic catalyst, and inactivation phenomenon caused by tar and coke attachment does not occur; moreover, the content of the tar and the coke in gas is almost equal to zero after the reforming, and the heat value of fuel gas is increased.
