How much acetylene can be obtained from natural gas containing 90% methane if the yield is 70%?

The synthesis of acetylene from methane is described by the following pyrolysis reaction. 2CH4 = C2H2 + 3H2;

From 2 methane molecules, 1 acetylene molecule is synthesized.

Taking into account the reaction yield of 70% and the methane content of 90%, the following volume of acetylene can be obtained from a unit volume of natural gas:

V C2H2 = 1 x 0.7 x 0.9 / 2 = 0.315%;

For example, from 1000 liters of natural gas under these conditions, it is possible to synthesize 315 liters of acetylene.
