摘要

Method for preparing a barrier chemistry going on in a gaseificau00e7ao reactor for black liquor, a reactor of gaseificau00e7ao quu00ecmico, a barrier layer of a reactor and a method for manufacturing a block construction for such a barrier layer, a chemical reactor and a method for preparing a barreir The ceramic in a gasification reactor.The reactor is prepared to convert organic waste of high energy type of black liquor with a large quantity of alkali metal compounds, inorganic or organic, through high temperature oxidation with air or oxygen.By means of the organic residue is converted to a hot gas reducer containing a considerable amount of water vapor and the inorganic compounds to form a fusion containing alkali salt at a temperature of 750 - 1150 198 C and the reactor wall is prepared to understand an exter In (14) with input and output devices associated with reagents and products.The method comprising the preparation of a lining (16, 18) comprising one or more layers of barrier ceramic (16, 18) on the inside of the wall (14).The ceramic barrier closer to (16) of the reactor is composed of a lining material mainly contains compounds of aluminium oxide (A1203) and at least one of oxides of alkali metal (T ^ (II) ^ m) and u00e1xidos metal alkaline earth silicate (T ^ (II) ^ o), forming a compounds of the type I ~ 2 ~. O.al ~ 2 ~ 0 ~ 3 ~ and I ^ (II) ^ o.al ~ 2 ~ 0 ~ 3 ~.
