PRODUCTION OF PRODUCER GAS, WATER-GAS, SYNTHESIS GAS FROM SOLID CARBONACEOUS MATERIAL, OR MIXTURES CONTAINING THESE GASES (synthesis gas from liquid or gaseous hydrocarbons C 01 B; underground gasification of minerals E 21 B 43/295); CARBURETTING AIR OR OTHER GASES [5]

Production of fuel gases by carburetting air or other gases without pyrolysis (for internal-combustion engines F 02)

Carburetting air

Controlling supply of air

with materials which are liquid at ordinary temperatures

by passage of air through or over the surface of the liquid

with the liquid absorbed on carriers

by atomisation of the liquid

Controlling the supply of liquid in accordance with the air supply

in rotary carburettors

Carburetting gases other than air

Adding materials to prevent vapour deposition

Controlling humidity of the air or gas to be carburetted

using raised temperatures or pressures

Odorising air gas
