The optimal pressure must be determined when considering the load of industrial production and the thermodynamic effects of methanation reaction in the normal production process. Then, the space—time yield of methane downward trend is more significant. This is because the contact time between the feed gas and the catalyst surface becomes shorter at high space velocity.
You are here:
The effective collision between reactants and feed gas is reduced, and the conversion efficiency of the methanation reaction is reduced. Production at low space velocity is beneficial to improve single pass conversion of carbon monoxide in the actual production process, but productivity of the reactor will be very low. Single pass conversion rate was lower in high space velocity operating conditions. In order to improve the utilization efficiency of the feed gas, the feed gas needs many cycles, which will increase the operation cost. Thus, a proper space velocity needs to be selected to ensure that the catalyst activity is optimal in the actual production.

According to the experimental results, the high pressure was not necessary for methanation reaction pressure at high temperature. The optimal pressure needs to be determined when considering the load of industrial production and the thermodynamic effects of methanation reaction in the normal production process. These parameters were suggested as most suitable for the process of syngas to methane conversion.

First Online: 29 July Introduction Methanation is one of the key techniques for the coal to synthetic natural gas [ 1 ]. Experimental device All the experiments were carried out with a high-temperature, high-pressure fixed-bed reactor system. The flow chart of the experimental apparatus is shown in Fig. Coal gasification.
