Flash pyrolysis of organic substances with ionic liquid as a heat carrier for the production of oily or gaseous intermediates

摘要

Flash pyrolysis method for biomass and organic residue input using a suitable ionic liquid for the production of a pyrolysis gas for use in gas CHPs or a slurry or a pyrolysis oil fraction, wherein the preparation of organic water-containing input material by a subassembly consisting of shredder (1), Conveying device (2), warm mixer (3), colloid pump (4) and intermediate container (5) with degassing / venting (6) is effected and by the admixture of ionic liquid having a temperature in the range of about 200-250 ° C is a Adjusting the mixing temperature, which produces a corresponding vapor pressure in the intermediate container and simultaneously sets a softening of the organic substance, whereby in the colloid pump a fine emulsion is realized, the actual pyrolysis in the plant combination hot mixer (7), main process pump (8), expansion and separation vessel (9) and a cyclone (9) is realized , the residence time in the area of the hot mixer pump can be adjusted in the range of 1-10 s by means of media recirculation and possibly entrained droplets of the ionic liquid are retained in an internal or external separator (9).
