I would need information about the quantity of chemicals and reaction temperature.
The following literture may be useful for your research
Laboratory Method
(A) Principle : In the laboratory,methane is prepared by heating a mixture of anhydrous sodium acetate and soda lime (NaOH + CaO)
CH3COONa + NaOH(CaO) --------> CH4 + Na2CO3
Sodium acetate Soda lime Methane
(B) Procedure : Anhydrous sodium acetate and soda lime are taken in the ratio 1:3 by weight and are mixed immediately.The intimate mixture of sodium acetate and soda lime thus prepared is taken in a dry hard glass test tube fitted with a cork through which a delivery tube passes.The hard glass test tube is now heated strongly when methane is evolved.The first part of the evolved gas is allowed to escape to remove the air inside the test tube.Methane thus produced is collected in a gas jar by the downward displacement of water
(C) Purification : Methane thus prepared contains traces of ethylene,acetylene,hydrogen and moisture as impurities.
(I)Acetylene is removed by passing the impure gas through ammoniacal cuprous chloride solution
C2H2 + CuCl2 ----NH3-----------> C2Cu2 + 2HCl
Ref:https://answers.yahoo.com/question/?qid=20110326232119AAGVaN2
Acetoclastic methanogen bacteria utilize acetate and make methane, anaerobically usually at 35C or higher temperatures. It may be mixed with CO2 in biological settings.
