REACTOR FOR NATURAL GAS CHLORINATION Russian patent published in 2010 - IPC B01J12/00 C07C17/02 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical technology and chemical machine building, namely to reactors of gaseous chlorination of natural gas (methane) and can be used in production of chlormethanes. Reactor for natural gas chlorination contains body (1), cover (2), bottom (3), socket for supply of reagents (4), socket for output of reaction products (5), located in lower part of the reactor body, and internal cup (6) placed coaxially with the body, cup bottom being matched with reactor bottom, in the centre of the cup placed is socket for supply of reagents. Through socket for supply of reagents into the reactor introduced is mixer of reagents consisting of two tubes placed coaxially with the mixer nozzle (7). In claimed construction process of natural gas chlorination is carried out in adiabatic conditions. Products of chlorination, located in circular cavity of the reactor, thermostatically control reactor cup (6) ensuring chlorination process stability. Reaction heat is removed with reaction gases, output through the socket (5) in lower part of the reactor.

EFFECT: prevention of methylene chloride and chloroform return into chlorination zone due to absence of internal recycle of reaction gases, which increases process selectivity and reduces formation of ozone-depleting carbon tetrachloride.
