Hot synthesis gas is cooled and deashed by passage through first zone in contact with a downwardly descending film of cooling liquid, a second zone in contact with a spray of cooling liquid, a third zone in contact with a body of cooling liquid, and a fourth zone in contact with a spray of cooling liquid－at least a portion of the cooling liquid to the first zone preferably being recycled cooling liquid from which at least a portion of the solids contained therein has been removed.

The method of cooling a hot synthesis gas which comprises passing hot synthesis gas at initial temperature downwardly through a first contacting zone in a quench chamber; passing cooling liquid downwardly as a film on the walls of said first contacting zone and a contact with said downwardly descending synthesis gas thereby cooling said synthesis gas and forming a cooled synthesis gas; passing said cooled synthesis gas downwardly through a second contacting zone in said quench chamber in contact with a downwardly descending film on the walls of said second contacting zone; spraying cooling liquid into said downwardly descending cooled synthesis gas in said second contacting zone thereby forming a downwardly descending further cooled synthesis gas; passing said further cooled synthesis gas into a body of cooling liquid in a third contacting zone in said quench chamber thereby forming a further cooled synthesis gas containing a decreased solids content; passing said further cooled synthesis gas containing a decreased solids content into contact with a sprayed stream of cooling liquid in a fourth contacting zone in said quench chamber thereby forming a cooled product synthesis gas; and recovering said cooled product synthesis gas.
