Abstract

The invention relates to a solar methane chemical-looping reforming reactor and a using method thereof. The solar methane chemical-looping reforming reactor comprises a rotatable reactor and a gas source connected with the reactor, an oxygen carrier is fixed at the central position of the reactor, an annular jacket is arranged at the outer side of the central position of the reactor, and molten salt is filled in the annular jacket; and a cuboid cavity is arranged outside the annular jacket, and a quartz glass window is arranged on the side, facing sunlight, of the cavity. Through the heat storage characteristic of part of the molten salt, the temperature change of a reaction zone, caused by external sunlight fluctuation, is reduced. The solar energy utilization rate can be improved, the solar heat flow density can be homogenized, the reaction is more stable and controllable, the inactivation of the oxygen carrier, caused by over-high local temperature, can be reduced, and the cost isreduced.

Description

technical field [0001] The invention belongs to the field of high-efficiency thermochemical energy storage of solar energy and the preparation and utilization of solar fuel, and specifically relates to a solar methane chemical chain reforming reactor and a use method thereof. Background technique [0002] Extensive use of coal, oil and natural gas has caused the depletion of fossil energy and environmental pollution. my country has clearly put forward the guidance to reduce the use of chemical energy and increase the proportion of renewable energy. Solar energy is the most abundant renewable energy source and has the potential to solve global energy demand problems, but its intermittency and instability greatly limit its application range. How to realize efficient and large-scale storage of solar energy is the key to efficient utilization of solar energy. The solar thermochemical energy storage process can effectively store and release solar energy through reversible reacti...
