Reactions that may take place during the tar carbonization process are methanation and Boudouard reactions.
They explain that C[H.sub.4] is produced mainly during the pyrolysis step and as the temperature increases, the production of CH4 remains almost constant because methanation reaction does not take place at any significant extent [4, 54].

Therefore, it is vital to maintain optimal condition to flourish the process of methanation. Biomethanation process primarily depends upon seeding, temperature, pH, carbon-nitrogen (C/N) ratio, volatile fatty acids (VFAs), organic loading rate (OLR), alkalinity, total volatile solids (VS), and hydraulic retention time (HRT) and nutrients concentration.
The [delta][sup.13]C showed obvious positive bias likely caused by decomposition and methanation (C[H.sub.4]) of organic matter caused by methane bacteria.
Grids in the Gulf suffer from large use in the summer and much lower base loads in the winter, which makes any breakthrough in large scale storage of power important, which include various battery options, newly invented graphene supercapacitors and even methanation via hydrogen electrolysis.
Methane can be used directly in gas-fired power plants and CNG vehicles, and the electrolysis and methanation conversion losses harnessed for heating the biogas plant, as at Werlte, and buildings, as at the Prenzlau power-to-gas plant.
It has also expanded the coke oven gas-produced methanation LNG project and set up gas storage facilities in regions where it conducts business to increase the temporary replenishment and supply from gas sources.
Ni catalysts are used in many industrial processes, such as hydrogenation, hydrotreating, hydrogenolysis, methanation and steam reforming of hydrocarbons [9].
