Abstract: Apparatus for contacting a gas with solid particles comprising a housing, an inlet space, an outlet space and at least one contacting unit, where the contacting unit comprises a first wall, a second wall parallel to the first wall, a plurality of gas conduits connecting the inlet space with the outlet space, which conduits are defined between the first wall and a permeable corrugated plate attached to the first wall on the side of the second wall, and a plurality of zones filled with particles defined between the second wall, the permeable corrugated plate and separating means positioned between the second wall and the permeable corrugated plate and perpendicular to the conduits.

Abstract: A process for removing HCN from gases, which may also contain a hydrogen halide, by hydrolysis in the presence of a supported metal from Group 3b and/or 4b, use being made of a silica-containing carrier or support.

Abstract: Pulverized coal is converted by means of a gaseous mixture and partial oxidation into synthesis gas which is subsequently utilized as a feedstock for the production of hydrocarbons. A gaseous mixture containing non-converted synthesis gas and low boiling hydrocarbons is separated from the higher boiling hydrocarbons and recycled to the coal conversion step.
