A natural gas and oxygen reactor (1) having a main combustion chamber (5) fed
by two feeding ducts (2, 6), for natural gas (G1) and oxygen (O) which mix and
combust in the pre-combustion chamber (4) placed between the feeding ducts (2,
6) and the main combustion chamber (5). A second gaseous mixture, made by
natural gas (G2) and oxidising gas (S), is first mixed in a mixing chamber (3) coaxially
surrounding the second chamber (4) and subsequently introduced in the
main combustion chamber (5) wherein it mixes with the burnt gas coming out of
the pre-combustion chamber (4) and undergoes the second combustion. The produced
final gases, rich in reducing compounds are useful for the reduction of iron
ores. A method for reduction of iron ores by means of a gas and oxygen reactor is
also disclosed.

In ein rohrfoermiges gehaeuse eingebauter elektrischer kondensator

Soot formation in the partial oxidation of carbonaceous feed is controlled by controlling the momentum of the oxidant stream relative to the momentum of the carbonaceous feed stream.

Soot control in oxidation reactions

(Part of) charge is reacted in flame produced from combustible gas mixture, gas stream (secondary gas) being intermixed in flame front. Secondary gas may consist of inert gas or one or more gaseous reactants. It can be introduced in same stream as combustible gas mixture or in transverse stream. Process is suitable for synthesis of unsaturated 2C hydrocarbons from light hydrocarbons and O2 and HCN from light hydrocarbons, NH3 and O2. Satisfactory yields are attained.
