Abstract
The invention relates to an apparatus used for evaluating catalysis performance of a catalyst. The apparatus comprises a distributing device, a hydrocarbon fuel bubbling apparatus, a tubular furnace for placing a to-be-measured catalyst, and a tail gas detection apparatus which are connected in order through pipelines; the hydrocarbon fuel bubbling apparatus is connected with the tubular furnace through a mixed gas pipeline, and a first stop valve is arranged at the mixed gas pipeline; auxiliary testing pipelines are arranged on the pipelines at an inlet end and an outlet end of the tubular furnace in a parallel mode, a second stop valve is arranged on the auxiliary testing pipeline, and the inlet end of the auxiliary testing pipeline is arranged between the first stop valve and the hydrocarbon fuel bubbling apparatus. The apparatus is capable of evaluating the catalysis combustion performance of the catalyst for hydrocarbon fuel in a simple and efficient mode, and is helpful for selecting the optimal catalyst for the different hydrocarbon fuels.
Description
technical field [0001] The invention relates to the field of catalytic combustion of hydrocarbon fuels, in particular to a device for evaluating the catalytic performance of a catalyst. Background technique [0002] Fuel tank explosion is one of the main factors that threaten the safety of aerospace, so the fuel tank inerting system that reduces the flammability of fuel tanks has always been a research hotspot for aircraft safety. The air separator-based onboard inert gas production system (OBIGGS for short) has become an inerting system widely used in domestic and foreign aircraft because it can effectively reduce the oxygen content in the fuel tank space and ensure the safety of the fuel tank. [0003] However, the OBIGGS system also has certain limitations in the application process, such as having a certain impact on the performance of the aircraft engine, adding additional weight to the aircraft, and expensive components. The green airborne inert gas production system ...
