Description

A kind of Fischer-Tropsch synthesis process being applicable to fixed-bed reactor
Technical field
The present invention relates to a kind of Fischer-Tropsch synthesis process being applicable to fixed-bed reactor.
Technical background
Coal produces oil fuel through F-T synthesis and chemical is one of the important content in clean coal technology field.Now, fluidized-bed, slurry bed system and fixed-bed reactor are main reactor of Fischer-Tropsch synthesis.Although fluidized-bed reactor heat transfer coefficient is high, heat-transfer effect good, be easy to automatic production, its fluid mapper process is restive, and catalyst utilization is low, back-mixing, serious wear; Although paste state bed reactor temperature of reaction is even, productive rate is high, also there is serious back-mixing, and the separation of catalyzer is also an insoluble problem; There is the poor feature of bed temperature skewness even bed thermal conductivity in fixed-bed reactor, but fixed-bed reactor volume is little, and catalyzer loading amount is little, is suitable for High Temperature High Pressure operation, is thus usually used in Fischer-Tropsch synthesis process.Particularly cobalt-base catalyst, it has high reactivity, high stability, low water gas shift reaction, low methane selectively, high C 5 +the advantages such as selectivity.But cobalt catalyst cost is higher, to be separated and the problem that runs off causes it not to be suitable for slurry bed system and fluidized-bed reactor, and to be preferablyly applied to fixed-bed reactor.But cobalt catalyst is used for fixed bed to be existed two problems and causes it can not industrial applications, and first is that reaction bed temperature is uneven, very easily temperature runaway; Second is that temperature inequality causes bed utilization ratio low, and productive rate is low.
The original intention of fixed-bed reactor design is exactly mainly take away with the form of the evaporation of water latent heat of vaporization amount of heat produced in reaction tubes.Boiled water is by heat exchange between pipe, and by-product high-pressure steam, enhances heat transfer process.But existing technique still effectively cannot remove the large calorimetric that fischer-tropsch reaction is released, and still there is the problem of beds temperature runaway.Since fixed bed can by the latent heat of vaporization heat radiation between pipe, so also it can strengthen heat transfer by the latent heat of vaporization effect in pipe, just urgently develops a kind of like this Fischer-Tropsch synthesis process that effectively can move heat in pipe at present.
