- 1. A process for producing hydrocyanic acid in the gaseous phase, which comprises introducing hydrocyanic synthesis gas into a heat exchange means; passing the resultant synthesis gas into a reactor having a single-walled pressure shell, a plurality of annular catalyst beds with particulate catalyst in each bed, and a plurality of annular-shaped cross-flow heat exchange means, said annular catalyst beds and said annular heat exchange means being alternatingly disposed; passing said synthesis gas through the first of said beds in a radially outward direction toward the pressure containment walls of said reactor; passing the effluent from said first bed through the first of said cross-flow heat exchange means in said radially outward direction; passing the resulting effluent successively through the next bed and the next cross-flow heat exchange means for each of the remaining beds and heat exchange means in said radially outward direction, each cross-flow heat exchange means providing inter-stage feed-effluent heat exchange, the shell-side fluid of said heat exchange means flowing radially outwardly in a direction substantially normal to the direction in which the tube-side fluid flows; and recovering a gas which is enriched in hydrocyanic acid.
