A reactor system for carrying out an endothermic catalytic chemical reaction in a given temperature range upon bringing a reactant into contact with a catalyst material. The reactor system includes a reactor unit arranged to accommodate catalyst material including one or more ferromagnetic macroscopic supports susceptible for induction heating where the one or more ferromagnetic macroscopic supports are ferromagnetic at temperatures up to an upper limit of the given temperature range. The one or more ferromagnetic macroscopic supports are coated with an oxide, and the oxide is impregnated with catalytically active particles. The reactor system moreover includes an induction coil arranged to be powered by a power source supplying alternating current and being positioned so as to generate an alternating magnetic field within the reactor unit upon energization by the power source, whereby the catalyst material is heated to a temperature within the temperature range by the alternating magnetic field.

A catalyst for inducing thermal desorption of organic matter-contaminated soil and a preparation method thereof, which uses a colloidal mixture of ferroferric oxide and ferric chloride as a catalytic active component of thermal desorption, and carbon tetrachloride as a solvent. Based on the mass of solvent, a mass percentage of catalytic active component is 0.1%-15%. Ammonia water is added dropwise to ferric chloride aqueous solution to react in oil bath to generate a ferroferric oxide colloidal solution, then ferric chloride and obtained ferroferric oxide colloidal solution are added to carbon tetrachloride, and mixed solution is continuously stirred in an oil bath to evaporate solvent water to prepare a catalyst with carbon tetrachloride as solvent. Catalyst is environmentally friendly and can induce thermal desorption of organic matters in soil. 100% desorption of chlorobenzene, o-xylene and benzo[A]anthracene can be achieved at 130° C., and energy consumption of thermal desorption is greatly reduced.

The present invention relates to: oxygen carrier particles having a metal oxide-perovskite core-shell structure; and a chemical-looping thermochemical water/carbon dioxide splitting process using the same. By using the oxygen carrier particles having a metal oxide-perovskite core-shell structure in the chemical-looping thermochemical water/carbon dioxide splitting process, it is possible to produce hydrogen/carbon monoxide from water/carbon dioxide in high yield by efficiently overcoming the disadvantages of conventionally used oxygen carrier particles.
