Abstract
To achieve better distribution of the fluid and optimal flow of bulk products, the feed inlet floor of a mobile bed reactor comprises parallel cellular bulk feed hoppers (9A) covering the surfaces or funnel shaped bulk discharge chutes (9B), the side walls (14A and 14B) of which are provided with openings (16A and 16B) for the passage of feed fluid above which roof-shaped feed distribution elements (18A; 18B; 18C) opening downward are arranged on the inner surface of the hoppers or chutes so as to project from the said surface. For flat, parallel flow of the bulk product, it is particularly advantageous that the distribution elements are arranged so that they also lie, in the direction of flow of the product, above the outlet openings (26A and 26B) for the latter in the hoppers or chutes and therefore preferably cover the entire surface region of the opening in the form of a roof. This type of feed inlet floor is advantageously used, amongst others, by adding to the intake fluid in the region of the said floor, another fluid component, for fluid treatment purposes, which then initiates a desired reaction in the region of fluid treatment and/or by extracting the bulk product from the reactor in cycles and in quantities corresponding to the contaminated layer of the product in the region of fluid treatment, and/or by using as intake fluid a gas or gaseous mixture the dew point of which is not attained at least in the lower horizontal region of fluid treatment. This non-attainment of the dew point is judiciously achieved by means of the feed inlet floor and makes it possible to carry out the fluid treatment in two phases, namely a first wet phase and a second dry phase.
