With the rapid development of world economy and the substantial increase in living standards, energy demand is increasing dramatically. As a mobile energy for fuel cell and to achieve high efficiency and zero emission car of the hydrogen energy, in recent years widespread concern around the world. Hydrogen is a new energy future of humanity is e to hydrogen combustion with high efficiency and no pollution.
It is precisely because of China's hydrogen technology instry is lagging behind and enormous development needs, and thus hydrogen proction technology in China have a greater prospects for development. Self-heating steam reforming of diesel fuel to improve the thermal efficiency of diesel fuel and recing pollution, therefore, self-heating steam reforming of diesel fuel the development of two major energy and environmental issues of great significance.
In this paper, straight-run diesel oil as raw materials to study self-heating steam reforming technology: the design of the precious metals, non-precious metal catalyst system; the use of sub-volume were prepared by impregnating one kinds of noble metal catalyst, three kinds of non-noble metal catalyst; the design of two diesel autothermal reforming reactor and experimental process, the formation of diesel autothermal reforming device; through the screening evaluation of the activity and stability of the catalyst; in the analysis of diesel-wide basis, through single-factor experiments and orthogonal experimental study and an analysis of influencing factors, optimizing the process conditions; a diesel re-engineering the process of self-heating of the thermodynamic analysis; studied methods to restore the catalyst to carry out the XRD, specific surface area, SEM characterization.
The results show that: In this reactor, the experimental device designed to meet the diesel requirements of self-heating steam reforming; PtLaCe/Al2O3, LaCeCoCrFeNi/Al2O3 catalyst has good catalytic activity and stability; single factor experiment results showed that the catalyst PtLaCe/Al2O3 LaCeCoCrFeNi/Al2O3 catalyst is superior to the activity. Orthogonal experiments show that, PtLaCe/Al2O3 catalyst operating conditions suitable for the 700 ℃, liquid space velocity of diesel 0.24h-1, water 20 C, oxygen and carbon than 0.6, Under these conditions, the hydrogen proction rate of 37.4mol/mol, hydrogen content was 55%; CHEMCAD thermodynamic process analysis and simulation results show that under these conditions are able to achieve steam reforming of diesel self-heating; In this paper, in situ rection of diesel options.

Along with the rapid development of the world economy and the level of human life, energy demand has increased dramatically. As a removable for fuel cell and the realization of energy efficiency and zero pollution emission car of hydrogen, in recent years have extensive attention of the world. Hydrogen is the future of humanity's new energy, because the hydrogen possess high combustion efficiency and pollution-free characteristics.
Because of our instry technology development hydrogen lagging and huge development needs, thus hydrogen proction technology in our country have larger development prospects. Since heat reforming hydrogen diesel fuel efficiency and improve diesel that rece pollution, therefore, diesel since the development of thermal reforming hydrogen for energy and environmental protection two big questions is important.
Based on the research straight-run diesel as raw material from hot reforming diesel hydrogen technology: the precious metals, non-noble catalyst system, Using piecewise constant water-volume impregnation method for the precious metal catalysts, three non-noble metal catalysts, Since the two diesel designing hydrogen reactor thermal reforming experimental process, and established the thermal reforming diesel hydrogen. Through the activity and stability evaluation screened catalyst, On the basis of analyzing diesel by single factor experiment, and the orthogonal experiment investigation and analysis of the factors affecting the process conditions and optimization, Since the reforming process of hot diesel thermodynamic analysis, The method of the catalyst, and specific surface area, XRD, SEM.
Research results show that: the reactor, the experiment device design is reasonable, satisfy the reforming diesel hydrogen requirements, PtLaCe/Al2O3, LaCeCoCrFeNi/Al2O3 catalyst has better catalytic activity and stability, Single factor experiment results showed that the activity PtLaCe/Al2O3 catalyst LaCeCoCrFeNi superior Al2O3 / catalyst. The orthogonal experiment shows that PtLaCe/Al2O3 catalyst suitable operating conditions for the 700 degrees Celsius, diesel hydraulic airspeed 0.24 h - 1, water, carbon, oxygen than 20 carbon than 0.6, in this condition, the hydrogen proction rate for 37.1 mol/mol, hydrogen content for 55%, CHEMCAD process thermodynamic analysis and simulation results show that the condition of diesel reforming hydrogen can realize hot.
