Description

A kind of acidic molecular sieve and resin compounded Catalysts and its preparation method
Technical field
The present invention relates to a kind of acidic molecular sieve and resin compounded Catalysts and its preparation method, this catalyst can be used in olefin hydration low-carbon alcohols processed, ether process.
Background technology
Olefin hydration is one of important organic catalytic reaction.In olefin hydration reaction tool represent meaning and with practical value be the reaction that olefin hydration is prepared corresponding alcohols, as ethanol, isopropyl alcohol, sec-butyl alcohol have purposes widely as important Organic Chemicals and solvent in industries such as coating, dyestuff, medicine, synthetic rubber, spices, agricultural chemicals.In recent years, along with the level of crude oil processing increases, produced a large amount of C 2~C 7alkene, and olefin hydration is the important means that consumes alkene, is also the important method of industrial production alcoholic product.Olefin hydration reaction is typical acid catalyzed reaction, and its catalyst is generally sulfuric acid and phosphoric acid, because above-mentioned two kinds of catalyst exist the problems such as burn into loss, is progressively replaced by zeolite catalyst and strong resin catalyst in recent years.Although strong resin has certain catalytic activity, due to its exist preparation complicated, easily inactivation, can not regenerate, the shortcoming such as production capacity is low, and make each research institution of the world be devoted to develop low-carbon alkene hydration zeolite catalyst.
Relevant zeolite molecular sieve catalyst is more for the research report of olefin hydration, as EP210793, EP323268, EP323268, EP458048, US4857664, US4727977, US5012014.Above-mentioned document shows that propylene hydration prepared in the zeolite that isopropyl alcohol/isopropyl ether adopts, and β zeolite effect is best.ZSM-5 has good catalytic effect to ethylene hydration, and butylene hydration sec-butyl alcohol processed adopts ZSM series effect good.Under olefin hydration reaction condition, zeolite-type molecular sieve has good catalytic performance, but is subject to the restriction of preparation condition, also exists hydrothermal stability of molecular sieve poor, under reaction condition, catalyst strength is subject to hydrothermal condition to affect decline rapidly, has limited the realization of its commercial Application.
CN1245738A discloses the method for a kind of low-carbon alkene hydration low-carbon alcohols processed.The catalyst that the method adopts is made up of beta-molecular sieve and the binding agent of modification, and modifying element is selected from least one in La, B, Fe, Ge, Ni, Cr, Co, Cu, Mg, Ca, Sr, Ge; Catalyst consists of (percentage by weight) modifying element 1 wt% ~ 5wt%, beta-zeolite molecular sieve 40 wt% ~ 80 wt%, binding agent surplus.It is binding agent that the method adopts Ludox, clay, aluminium hydroxide etc., and the catalyst hydrothermal stability of preparation is poor, under olefin hydration reaction condition intensity decline too fast, be difficult to realize commercial Application.
CN1872826A discloses a kind of method of continuous production lower alcohol, adopt hydrating process, 80~200 ℃ of reaction temperatures, reaction pressure 4.0~20.0MPa, solid acid catalyst adopts cationic ion-exchange resin, low-carbon alkene catalysis hydration is become to low-carbon alcohols, and the alcohol in reaction afterproduct is separated.Catalyzing cation exchange resin olefin hydration conversion per pass lower (<10%), along with reaction is carried out, sulfonate radical runs off and causes equipment corrosion, and needs supporting deionized water system to remove the ion in recirculated water, complex technical process.
Acidic molecular sieve is also for alkene direct hydration etherificate coproduction correspondent alcohol and ether technology, especially propylene hydration etherificate diisopropyl ether processed.Diisopropyl ether blending octane number is high, and Reynolds steam forces down, and exhaust emissions amount is few, is a kind of desirable gasoline additive, and the research that propylene one step hydration and etherification is prepared isopropyl alcohol and diisopropyl ether in recent years comes into one's own day by day.
US 5231233 discloses the propylene hydration etherification method take layer column type MCM-36 as catalyst, at 7.0MPa, 160 ℃, water alkene weight ratio 0.92, LHSV 0.69h -1the different ether of propylene conversion 17.2%, two selective 10.9% under condition.The method propylene conversion and diisopropyl ether are selectively all lower, have limited its commercial Application.
CN 101757942A discloses the method for a kind of Y zeolite through Cr, Mo modification for propylene etherificate diisopropyl ether processed.The method reaches 90%, diisopropyl ether selective 95% take propylene, water, isopropyl alcohol as raw material at 160 ℃, 2.5MPa, alcohol/alkene mol ratio propylene conversion under 1.0 condition.The method, owing to having introduced isopropyl alcohol, has increased separation of products difficulty, and technical process is more complicated.
CN 1298761A discloses a kind of method of beta-zeolite molecular sieve modification, prepares the method for diisopropyl ether for propylene one-step method hydration and etherification, and the method is take propylene, water as raw material is at 160 ℃, 7.0MPa, propylene air speed 0.5h -1under condition, propylene conversion 60%, diisopropyl ether selective 71%.
Acidic molecular sieve is applied in olefin hydration, etherification reaction process, has good catalytic activity, but rarely realizes at present commercial Application, and main cause is because molecular sieve all uses SiO in preparation process 2, Al 2o 3, SiO 2-Al 2o 3, clay, aluminium hydroxide etc. are binding agent, such binding agent has under the reaction condition that water exists in hydration, etherificate etc., hydrothermal stability extreme difference, intensity reduces rapidly, is difficult to reach commercial Application requirement.
