摘要： The invention relates to a method for converting a gas into methane (CH4) which includes: a step of activating a catalytic material including praseodymium oxide (Pr6O11) associated with nickel oxide (NiO) and alumina (Al2O3), the respective proportions of which are, relative to the total mass of these three compounds: Pr6O11: 1 wt % to 20 wt %,NiO: 1 wt % to 20 wt %, andA12O3: 60 to 98 wt %; and a step of passing a gas including at least one carbon monoxide (CO) over the activated catalytic material.

摘要： The device (100) for hybrid production of synthetic dihydrogen and/or synthetic methane comprises:
an inlet (105) for a synthesis gas stream preferably comprising at least CO and H2,
a catalytic conversion reactor (110), the following alternative configurations:
a first configuration in which the operating conditions of the reactor promote a Sabatier reaction, so as to produce an outlet gas comprising mainly methane, or
a second configuration in which the operating conditions of the reactor promote a water gas shift reaction, so as to produce an outlet gas comprising mainly dihydrogen;
an outlet (115) for synthetic dihydrogen and/or synthetic methane and
a control system (120) comprising a means (121) for selecting a configuration for operating the reactor and a control means (122) according to the selected configuration, the reactor being configured to operate according to a command.
