The method has the steps of providing a flow reactor; endothermically reacting carbon dioxide with hydrocarbons, water, and/or hydrogen in the flow reactor, at least carbon monoxide being formed as the product, under the effect of heat generated electrically by one or more heating elements (110, 111, 112, 113); and at the same time exothermically reacting hydrocarbons, carbon monoxide, and/or hydrogen as reactants in the flow reactor. The exothermic reaction releases a heat quantity Q1, the electric heating of the reactor releases a heat quantity Q2, and the exothermic reaction and the electric heating of the reactor are operated such that the sum of Q1 and Q2 is greater than or equal to the heat quantity Q3 which is required for an equilibrium yield Y of the endothermic reaction of ≥ 90%.

[PETASCH UWE, MARTIN HANS-PETER, HERRMANN MATHIAS, KASKEL STEFAN, KOCKRICK EMANUEL] DE Porous silicon carbide composite production involves providing active functional centers. A microemulsion with a chemical compound or element for formation of an active functional center is produced. The functional center is an oxide, hydroxide, nitrate, chloride, acetate, sulfate, acetylacetate, citrate, metal and metal alloy in water with a non ionic surfactant as well as an oily component and an organic silicon contained compound. The microemulsion of a thermal treatment is subjected at 1100-1500[deg] C in an inert atmosphere for synthetic formation of silicon carbide containing functional centers and subsequently still contained residual carbon is removed in an oxidizing atmosphere at 1000[deg] C.
