Abstract: Aspergillus cejpii is used in metabolism of a flammable and explosive gas. It has been determined that Aspergillus cejpii S8 exhibits an excellent absorption and metabolism effect for a flammable and explosive gas such as hydrogen and methane, and a mixed gas including the flammable and explosive gas. The Aspergillus cejpii S8 strain can undergo a metabolic process with a flammable and explosive gas or a mixed gas including the flammable and explosive gas as a carbon source and/or an energy source, thereby achieving the efficient treatment of the flammable and explosive gas or the mixed gas including the same. The Aspergillus cejpii S8 strain demonstrates high environmental safety and a prominent removal effect and can be conveniently used without toxic and side effects, which facilitates the application and transformation.

Abstract: A compound equipment of a latex-free tufted carpet is provided. The compound equipment includes an unwinding device, a compound roller, and a shaping device. The unwinding device is configured to unwind a rolled blank blanket, a hot-melt fiber mesh, and secondary cloth. The compound roller is configured to stack and compound the unwound blank carpet, the unwound hot-melt fiber mesh and the unwound secondary cloth in sequence to obtain a preformed tufted carpet. The shaping device is configured for the setting of the preformed tufted carpet at a preset temperature to obtain a finished tufted carpet. Combined with the hot-melt fiber mesh, the secondary cloth and the blank carpet are consolidated by means of thermally induced bonding, and latex is not needed for consolidation.
