Description
Technical field
The present invention relates to the method for increasing that a kind of furfuran compound aromatization turns to aromatic hydrocarbons, especially raising benzene, toluene, two
The ratio of the important basic organic chemical industry raw material such as toluene in the product.
Background technique
Benzene, toluene and dimethylbenzene are the important basic organic chemical industry raw materials of social development, its own or pass through reproduction
Multiple product chain can be derived, product is widely used in the numerous areas such as polyester, chemical fibre, rubber, medicine and fine chemistry industry, state
Interior consumption figure reaches up to ten million tons, has great influence to the national economic development.Benzene is a kind of basic petrochemical material of multipurpose, can
To produce numerous products, including ethyl benzene/styrene, cumene/phenol etc. derived from it.Paraxylene is mainly for the manufacture of right
Phthalic acid gathers cruel fiber such as producing by terephthalic acid (TPA) (PTA) or diethyl terephthalate (DMT) intermediate
Polyethylene terephthalate (PET), resin and film.These three types of aromatic hydrocarbons are typical light aromatics, are abbreviated as BTX.Mesh
The production of preceding domestic and international BTX depends on non-renewable fossil resource, such as can be by a catalyst by petroleum by adding
The technical process such as hydrogen, reformation, aromatic hydrocarbons conversion and separation obtain.But fossil resource reserves are limited and non-renewable, so that with
Petroleum is that the cost that main refining raw material produces aromatic hydrocarbons is more shown in surging.In addition, continually developing for fossil resource is a large amount of using generating
Greenhouse gas emission, caused a series of environmental problems are on the rise, therefore develop from renewable resource route and produce aromatic hydrocarbons
Significant and application value.
The plant that nature is widely present is a kind of typical renewable resource, belongs to one kind of biomass.Global biology
The annual yield of matter is about 200,000,000,000 tons, and rich reserves are from a wealth of sources, cheap and easy to get.From reproducible biomass resource
It is prepared with the extensive concern that widely applied aromatic hydrocarbon product causes scientific circles and industry.
Currently reported to convert biomass into BTX, a kind of method is that the complete thermal cracking gas of biomass is turned to synthesis
Gas (CO+H2), using F- T synthesis technology prepare BTX, as Sasol company develop Fischer-Tropsch high temperature (350 DEG C) synthesis technology,
Alkene and Determination of Alkane Content are more than 80% in product, arene content about 6% (Zhou Congwen etc., Shenhua science and technology, 2010,8 (4)：93-
96).In terms of the process, F- T synthesis can be used as a kind of transform mode of gasification of biomass, but its major product is alkane and alkene
Hydrocarbon, aromatic hydrocarbons only account for small part.Second class is to convert Biomass Syngas to methanol, continues aromatization process later
To obtain aromatic hydrocarbons.Convert methanol and dimethyl ether to by multiple reactors the mistake of aromatic hydrocarbons as US, P 4686312 are reported
Journey, converts methanol into after aliphatic hydrocarbon that aromatization turns to aromatic hydrocarbons again first, and that there is processes is long for the process, and aromatics yield is not high
Problem, in addition the carbon in biomass gasification process in biomass material there are about 50% is converted to carbon dioxide rather than an oxidation
Carbon, gasification efficiency are relatively low.Therefore synthesis gas is converted biomass into, using F- T synthesis or the route of aromatization of methanol
The deficiencies of step is long, and the yield of aromatic hydrocarbons is not high.
