Abstract

The invention relates to a simulation system for predicting auto-thermal reforming reaction of diesel oil, a prediction method and a medium. The simulation system comprises a first simulation module for simulating auto-thermal reforming main reaction and complete oxidation reaction, a second simulation module, which is used for simulating the reaction of generating deposited carbon through high-temperature cracking, the reaction between micromolecular olefin and alkane and the reaction of generating macromolecular alkane or aromatic hydrocarbon through unconverted or incompletely converted diesel oil, a third simulation module, which simulates the accompanying reaction, and a summarizing module, which obtains the product and the product content in the auto-thermal reforming reaction of the diesel oil to be predicted according to the prediction reaction results of the second simulation module and the third simulation module. According to the simulation system for predicting the auto-thermal reforming reaction of the diesel oil, the simulation modules and the connection relation are highly matched with the actual reaction type and the reaction relation of the auto-thermal reforming reaction of the diesel oil, so that the composition and the content of the auto-thermal reforming reaction product of the diesel oil can be better predicted, and the composition and the content of the auto-thermal reforming reaction product of the diesel oil are closer to those of the actual reaction product.

Description

technical field [0001] The present application relates to the field of energy technology, in particular to a simulation system, prediction method and medium for predicting diesel autothermal reforming reaction. Background technique [0002] In response to the energy crisis and environmental pressure, the clean and efficient utilization of fossil fuels has become an important research topic in the energy field. Diesel-fuel cell power generation technology is an effective way to cleanly and efficiently utilize diesel. Diesel produces hydrogen-rich gas through reforming reaction, which is supplied to fuel cells for power generation, which not only improves the efficiency of diesel energy utilization, but also solves the problem of hydrogen sources for fuel cells. Diesel reforming methods mainly include steam reforming, partial oxidation reforming and autothermal reforming. Steam reforming requires a large amount of external heat supply, the system structure is huge, and it is...
