Description

technical field [0001] The invention relates to the technical field of catalytic reaction devices, in particular to an electrothermal catalytic reactor. Background technique [0002] Due to the intermittent and fluctuating characteristics of renewable energy (such as wind energy and solar energy), renewable energy generation systems such as photovoltaic power generation and wind power generation cannot output power continuously and stably for a long time, and their large-scale grid connection requires the development of energy storage technology. support. Power-to-gas technology is an energy storage technology that converts electrical energy into chemical energy. Due to its characteristics of large capacity, long cycle, unrestricted by geological and terrain conditions, and the development prospect of deep coupling of natural gas network and power grid, in recent years received widespread attention. However, high cost is still the key problem restricting its large-scale ap...
