Description
Technical field
The present invention relates to the manufacture method of highly active catalyst for coal liquefaction, in more detail, relate to and make that to make iron be catalyst for coal liquefaction composition high degree of dispersion, and attached to the manufacture method of the highly active catalyst for coal liquefaction on the carrier that constitutes by micro mist shape coal.
Background technology
For a long time, obtain in that coal is carried out hydrogenation carrying out technological development aspect the direct coal liquefaction method of liquid fuel always, it is generally acknowledged that its most important technology essential factor is to improve the activity of catalyst for coal liquefaction (hydrogenation of coal catalyst).As catalyst for coal liquefaction, desired key element is the yield height of oil, and in generating oil the yield height of matter oil in the shared lightweight, low price, and catalyst consumption is few.The catalyst of these key elements is satisfied in exploitation comprehensively, be realize that direct coal liquefaction method is business-like must obligato technical research problem.
It is generally acknowledged that in the past noble metal series catalysts such as molybdenum, nickel, cobalt are highly active, but its price is very high, and when being used for catalyst of direct coal liquefaction, cost recovery that is used for using repeatedly and poisoning regeneration cost are too high, so practicality is lower.
On the other hand, though the catalytic activity of Fe-series catalyst is poorer than the noble metal series catalysts,,, researching and developing it as business-like catalyst from can disposable viewpoint considering usually from its low price always.
But as Fe-series catalyst, making with the most use is the catalyst that derives from natural pyrite natural materials such as (iron sulfide), though the low price of these catalyst itself, but in order further to improve its catalytic activity, usually how to pulverize the particle diameter of catalyst very little as the exploitation problem.
As the method for dwindling this catalyst particle size, open the spy and to have announced in the flat 6-99071 communique by iron sulfide or iron oxide are reached capacity and proceed again after the particle diameter to pulverize, obtain the situation of high activity catalyst for coal liquefaction.And the red soil that has obtained when also having enumerated various ores, refined aluminum as the raw material of aforesaid compound, the regulus that produces when making iron and steel have also been enumerated the situation as the Dry-crusher of available pulverizer respectively.
But the pulverizing cost of method shown in the above-mentioned communique is very high, certain limit is also arranged aspect active improving, so catalyst consumption is many, so the residue of coal liquefaction (dead catalyst) amount is many, exists the high problem of residue cost of handling.
As making this Fe-series catalyst particle diameter become very little, and improve active method, developed ammonia/iron precipitation method Fe-series catalyst synthetic methods such as (AWIP methods).The AWIP method is in the coal existence or does not have under the condition of coal, and ferric sulfate and ammonia, oxygen, carbonic acid etc. are reacted in the aqueous solution, separates out iron hydroxide, FeO (OH), ferric carbonate etc., generates the catalyst component (catalyst precarsor) of fine (several~tens nanometers).Under the coal existence condition, the catalyst component high degree of dispersion of generation is attached to the surface of coal, and the result can obtain highly active catalytic effect with little amount of catalyst, reduces the cost that catalyst is pulverized etc.
Catalyst component in the aqueous reaction solution that obtains by catalyst component generation/dispersion step, in can dehydration/drying process below as dry body separation and Extraction, and and feed coal, fusion Sulfur (co-catalyst) etc. offer the liquefaction reaction operation with the slurries form together, one side is blown into hydrogen, and one side is carried out liquefaction reaction.
But in business-like extensive coal liquefaction craft flow process, (wet type) makes catalyst component (catalyst precarsor) high degree of dispersion and attached to the method on the coal in the aqueous solution, the equipment operation cost and the unit scale that the coal of attached catalyst are dehydrated operation all will become excessive, therefore the catalyst generating apparatus also will become huge, exist the shortcoming that equipment and operating cost increase.
Under the condition that does not have coal to exist, generate this catalyst component (catalyst precarsor), as separating catalyst, the equipment of its extracting method and operating cost are low to be an advantage, but consider from the catalytic activity aspect, originally very fine catalyst component (catalyst precarsor) can cause secondary aggregation, form the particle diameter of several microns sizes, thus exist can not get resembling aforementioned under the coal existence condition highly active shortcoming the gained catalyst component.
The spy opens in the flat 3-131683 communique on the other hand, thereby as making the Fe-series catalyst high degree of dispersion improve the method for catalytic activity, the case of wet attrition of coal and solvent (oil) and Fe-series catalyst being carried out together machinery is disclosed, make it form slurries, add the sulphur of molten condition in these slurries, mixed hydrogenation makes the method for coal liquefaction.
Open the spy and to disclose in the flat 11-76823 communique being crushed to average grain diameter at the comminuted coal below 20 microns with pulverize iron compound and mix with 1/3~3 weight rate, and make its dispersion remain on slurry catalyst in the oil, the gross weight of said mixture is 60~40 weight % of slurry catalyst overall weight in this slurry catalyst, and remaining is an oil.Also enumerated iron sulfide as aforementioned iron compound.
But in the method that these Te Kaiping 3-131683 communiques and the flat 11-76823 communique of Te Kai are introduced, because is oleophobic property with iron sulfide (pyrite), iron hydroxide, FeO oleophobic property inorganic constituents such as (OH) as the Fe-series catalyst (separating catalyst) of principal component, so in organic solvent (oil), carry out in the method for case of wet attrition with coal, its wetability is bad, if so make particle diameter become very fine, in solvent (oil), carry out high degree of dispersion certain limit is arranged, improve active aspect, be difficult to obtain tremendous progress.
