Technical field
The invention belongs to energy technology field, and in particular to a kind of conversion of biomass thermal produce fuel oil or
The method of other chemicals, relates more particularly to for by biomass pyrolytic or the derivative pyrolysis of its pyrolysis
The catalytic deoxidation of oil and the method that produces pyrolysis oil derived from hypoxic bio matter.
Background technology
Fast pyrogenation is that one kind uses pyrolysis reactor by organic carbonaceous biomass material, i.e. " biomass ",
300-900 DEG C is quickly heated up under anaerobic, it is produced solid product, product liquid and gaseous state
Thermal decomposition product.The condensable part (steam) of gaseous pyrolysis product is condensed into pyrolysis oil.Biomass pyrolysis oil
Can directly be burnt as fuel for some boilers and Industrial Stoves application, and be alternatively arranged as catalysis
Potential raw material in method is used to produce fuel in oil plant.However, biomass pyrolysis oil is complexity
Height oxygen close organic liquid, its property limits its use as bio-fuel at present.
For example, biomass pyrolysis oil has highly acidity and low energy densities, its major part is attributable in oil
Oxygenated hydrocarbons, it undergoes secondary reaction during storing.This kind of oxygenated hydrocarbons in biomass pyrolysis oil include
Carboxylic acid, phenol, cresols, alcohol, aldehyde etc..Pyrolysis oil derived from standard biologic matter includes more than 30wt%
The oxygen from these oxygenated hydrocarbons.Biomass pyrolysis oil changes into bio-fuel and chemicals needs biology
The deoxidation wholly or in part of pyrolysis oil derived from matter.This deoxidation can be via two main routes, i.e. water
Or CO2Elimination and carry out.But biomass pyrolysis oil deoxidation is easily caused into catalytic pyrolysis, catalysis
Pyrolysis or quick carbon distribution, blocking, the inactivation of catalytic hydrogenation treatment catalyst reactor.Obviously, just
It is the heat or acid catalyzed polymerisation due to each component of biomass pyrolysis oil, such as oily each component itself gathers
The second order reaction of conjunction.Accordingly, it is desirable to provide for producing hypoxic bio matter pyrolysis oil without blocking
