METHOD OF OBTAINING SYNTHETIC GAS AND DEVICE TO THIS END Russian patent published in 2009 - IPC C01B3/36 

FIELD: chemistry.

SUBSTANCE: methane or natural gas is mixed with air, the mixture is forcibly ignited and methane is oxidised with atmospheric oxygen in a combustion chamber. Methane is completely oxidised in the combustion chamber. From the products of the oxidation process and atmospheric nitrogen, carbon dioxide is separated, and then mixed with methane again. Complete carbon dioxide conversion of methane is carried out in a reaction chamber, obtaining synthetic gas. The device comprises a combustion chamber 2, for methane or natural gas with atmospheric oxygen, and a mixer 4. The combustion chamber contains an ignition device and is made in form of a flow chamber, the outlet of which is attached to the mixer through an anti-slippage frame 3. Pipes 5 and 6, carrying methane and air respectively, are connected to the mixer. The outlet of the combustion chamber is connected to a heat exchanger 8 for cooling oxidation products and heating air, which is fed into the combustion chamber. The heat exchanger is provided with a socket piece for outlet of oxidation products. The device is also provided with a system 11, for releasing carbon dioxide, carbon dioxide and methane mixer 13 and a carbon dioxide conversion chamber 15, put in the combustion chamber The carbon dioxide conversion chamber is made in form of a flow reactor with walls of heat resistant material.

EFFECT: obtaining concentrated synthetic gas with high output, using air as an oxidising agent, reduced soot output, possibility of regulating content of synthetic gas.
