Background technique
With the development of society, the problems such as energy shortage, environmental pollution and greenhouse effects have become countries in the world political affairs
Mansion focus of attention.In order to protect environment for the survival of mankind and make sustained economic development, clean new energy is developed and can
The renewable sources of energy are becoming the common choice of countries in the world economic development.Hydrogen Energy, both can be with as a kind of zero carbon or low-carbon energy
Storage can be convenient and transport again, and the great change of energy resource structure may be brought using it as " the hydrogen economy " of core, thus reduce or
Politics for the purpose of fighting for petroleum, military conflict are eliminated, world peace is conducive to.
New technology is utilized as clean efficient " hydrogen economy ", the preparation of hydrogen energy source and the application of fuel cell have become thus
Two important core problems in field.As Hydrogen Energy is goed deep into what fuel cell technology was researched and developed, small distributed and portable combustion
Material battery power supply system gradually becomes new industry growth point, by the further neck for expanding Hydrogen Energy and fuel cell technology application
Domain.However, the link of Hydrogen Energy preparation seriously constrains the further development of current Hydrogen Technology.Although commercial scale hydrogen producing technology
Apply comparative maturity, but by its simple diminution be far from satisfying fuel cell technology commercialization to the cost of fuel hydrogen and
The requirement of interface relevant art.
Therefore, many researchers study small-sized hydrogen-manufacturing reactor: in order to reduce reactor volume, will pass
The multifunctional reactor that heat, mass transfer, differential responses process synthesis carry out is one of hot spot of research.In all about miniaturization hydrocarbon
Class, alcohol reforming hydrogen production reactor research in, most crucial critical issue is exactly the biography improved between heat releasing source and heat sink
The thermal efficiency.General using dislocation INDIRECT COUPLING mode, that is, catalysis is burnt or other exothermic reactions are as heat source, utilizes heat exchange
Mode be hydrogen manufacturing endothermic reaction heat supply, can utmostly improve density of hydrogen in product gas.Since such suction heat release couples
Hydrogen-manufacturing reactor involved in strong exothermal reaction and strong endothermic reaction and strong exothermal reaction and evaporation coupling, wherein heat
System arrangement will directly influence the performance of reaction.Once irrational distribution of the heat in entire reaction system, will lead to more
Kind negative effect, such as reaction conversion ratio is low, catalyst inactivation and byproduct of reaction are more, more seriously such case can
The pipeline that reactor can be damaged and its be connected with reactor.Most typical in the negative effect of heat irrational distribution is exactly to react
The bad control of device temperature, so that the selectivity of catalyst and yield are lower.In addition, for hydrogen feedstock (alcohol, alkane etc.) will be contained
