The problems such as.
Current 90% or more the energy both is from non-renewable fossil fuel (coal, former oil and gas).However, fossil
Consuming excessively for fuel is to increase CO in atmosphere2The main reason for discharge amount, therefore greenhouse effects are brought again, threaten all biologies
Existence.Utilize renewable energy (wind energy, solar energy, biomass energy, underground heat and hydroelectric generation etc.) replacing as fossil fuel
Dai Pin, which has become, realizes one of most potential development tactics of sustainable development society.Wherein, (one kind is abundant for biomass energy
Non-fossil carbon source) be capable of providing various valuable function chemicals and high energy density fuel.
The effective valueization of biomass utilizes and is not only to provide useful fuels and chemicals, while can also pass through progress
Photosynthesis and biorefinery technique reduce CO2Discharge amount.Thus, it is expected that the year two thousand thirty, the part of bio-fuel in transport service
Volume is up to 9% or so.It, can also be in sustainable development using natural biomass abundant as the raw material of chemicals production
Promote the development of Green Chemistry under background.
Catalytic hydrogenation treatment method plays very crucial effect during biomass is converted into fuel chemicals.
Heterogeneous solid catalyst has multiple physicochemical property, and high hydrothermal stability, efficient catalytic restore and repeatability,
Homogeneous liquid catalyst is substituted using them, is significantly during biomass higher value application.
In fact, heterogeneous catalysis field accounts for 90% of chemical production processes or so, and the industrial products more than 20% are raw
It produces.Partial size, shape and the porosity of solid catalyst play huge effect in catalysis reaction.
Heterogeneous catalysis is the one kind for converting renewable biomass to the advanced fuel and fine chemicals of sustainable development
Promising technology.Porosity and nanostructure are heterogeneous solid catalyst features the most general, these features determine special
Determine the accessibility in reactivity site, the selectivity of reaction mechanism and required product.Therefore, to the porosity of catalyst and nanometer
The accurate adjustment of structure has become a kind of potential mode of exploitation Novel solid-catalyst, achieves more efficient biomass
Catalyzed conversion.
Catalyst particle form is finely adjusted, especially metal or metal oxide, the electricity of catalyst surface will be optimized
Son and geometrical property.The nano-metal-oxide of controllable shape can preferentially expose exhibiting high surface active crystal face.Therefore, may be used
To enhance the interaction between active site and active material, biomass hydrogenation deoxidation reaction efficiency can effectively improve.
Other than partial size and form, selection of the porosity of solid catalyst for raising catalyst activity and product is controlled
Property is also very important.The pore size of solid catalyst can directly affect the diffusion of active material in biomass conversion reaction
Characteristic.In addition, using specific porous material that can mutually provide specific absorption as the carrier of catalyst for stable catalytic activity
Site.
Due to biomass molecule be it is complicated and highly viscous, use these single mode porous materials to urge as biology correlation
The significant challenge of agent is the obstruction that can encounter mass transfer during the reaction.
Therefore, the research of the porous bimetallic catalyst of support type has caused researcher more and more to pay close attention to.Develop function
The industrial applications that the bimetallic catalyst of energyization is converted into platform chemicals to veratryl alcohol have realistic meaning, while meeting can
The strategic requirement of sustainable development.
