Description
Technical field
The present invention relates to a kind of catalyst, more particularly to a kind of biomass liquefied oil catalytic cracking dehydrogenation catalyst, belong to
Catalyst field.
Background technology
With the increasingly depleted being continuously increased with oil of energy demand, seek a kind of new energy of alternative traditional fuel
The inevitable requirement for solving energy shortage, maintaining social development is turned into.Biomass energy is regenerative resource, wide material sources, including：
Timber and forest industry discarded object, agricultural wastes, water plant, city and industrial organic wastes, animal wastes etc..Its is excellent
Point is that sulphur, nitrogen content are low, and environmental pollution is small in process；Organic matter is changed into fuel and reduces public hazards, is following energy
Chief component in source structure.But the depth of biomass utilization is inadequate, and industrialized condition is immature, especially in profound profit
Larger space with aspect be present.It is that biomass energy deep processing should wherein by biomass liquefying product (bio-oil) upgrading refining
One of approach.Due to the complicated component of biomass liquefying product, there are the compounds such as alcohols, ethers, acids, hydro carbons, phenols,
The problems such as oxygen content is high, calorific value is low, moisture and acid number are higher, is not suitable as engine fuel and chemical products is straight
Connect utilization.Have high oxidation, unstability, sticky, corrosivity, strong hygroscopicity and chemical composition complicated for bio-oil
The features such as property, traditional petroleum fuel is directly substituted to be very limited with it, therefore, it is necessary to refined, improved to it
Its quality is to reach fuel oil requirement.
At present, bio-oil process for purification can be divided into physics method for refining and chemical refining method.Physics is refined mainly to be passed through
The means such as solvent, emulsification are added to complete, although its calorific value can be improved, are restricted using field.Chemical refining mainly collects
In in catalytic hydrogenation, catalytic pyrolysis, catalytic esterification etc., no matter be to urge using any chemical refining method, its key technology
The exploitation of agent pair.The oil quality that catalytic hydrogenation obtains is higher, but because equipment requirement is high, abrasion is big, and technical requirements are high, whole
Costly, while the blocking of the inactivation of catalyst and reactor restricts the development of this technology to individual process.Catalytic cracking process
Bio-oil is cracked under the conditions of existing for catalyst, oxygen is deviate from the form of CO2, H2O or CO.The process reaction
Condition is gentleer, it is not necessary to is hydrogenated with, consersion unit requires that no catalytic hydrogenation is strict, thus has very big development potentiality, together
When catalytic pyrolysis refined raw material oil yield it is relatively low, coking rate is high, and catalyst life is short, therefore how to improve process catalysis
Activity, selectivity and the anticoking capability of agent, turn into the crucial and anxious bottleneck to be broken through of tackling key problem.
