Abstract:
1. A method for regulating the heat and the CO 2 concentration of the air in an enclosed space within which plants or crops are grown, in which method an oxygen-containing gas and a hydrocarbon-containing gas are alternately passed over a bed of particles that are capable of binding oxygen, wherein the oxygen-containing gas is passed over the bed of particles at a temperature of 100 to 1,500° C. and a pressure in a range of 1 to 100 bar whereby the particles are oxidised and heat is released, after which at least part of the heat is provided to the enclosed space, and wherein the hydrocarbon-containing gas is passed over the bed of the oxidised particles at a temperature of 300 to 1,500° C. and a pressure of 1 to 100 bar whereby the oxidised particles are chemically reduced and water and CO 2 are formed, after which at least part of the CO 2 so obtained is provided to the enclosed space.
