Method and device for the plasma-catalytic conversion of materials

A method for the production of key chemicals by plasma-catalytic conversion of starting materials, wherein

• a hydrocarbon-containing starting material selected from the group consisting of natural gas, biogas, pyrolysis gas, methane, ethane, propane, butane, isobutane, liquid or gasifiable hydrocarbons, and combinations thereof is converted, under the action of a plasma, with at least one further starting material, to at least one product,
• or
• a hydrocarbon-containing starting material selected from the group consisting of natural gas, biogas, pyrolysis gas, methane, ethane, propane, butane, isobutane, liquid or gasifiable hydrocarbons, and combinations thereof is converted in a first method step, under the action of a plasma, to one or more intermediate products(s) which, in at least one subsequent method step, are converted to a reaction product,
• wherein the hydrocarbon(s) of the hydrocarbon-containing material consist of hydrogen and carbon, and
• wherein the conversion under the action of plasma is effected in a plasma reactor with the plasma gas present in the plasma reactor, which plasma gas contains the products or intermediate product(s) produced, and wherein
• (i) the product(s) or intermediate product(s) produced by plasma-catalytic conversion is/are introduced into a scrubbing liquid containing at least one catalyst or at least one reactant, with at least one of these products or intermediate products being converted in the scrubbing liquid by the catalyst or reactant to produce said key chemical;
• or
• (ii) the starting materials introduced into the plasma reactor are conveyed by a liquid jet pump located downstream of the plasma reactor and the products or intermediate products are continuously removed from the plasma reactor by the liquid jet pump, wherein a solvent which contains at least one reactant and/or a liquid which contains at least one catalyst is/are used as a motive fluid of the liquid jet pump for further conversion of the products or intermediate products to produce said key chemicals.

A method for the plasma-catalytic conversion of materials, in particular for the production of key chemicals, wherein

• a hydrocarbon-containing starting material selected from the group consisting of natural gas, pyrolysis gas, biogas, methane, ethane, propane, butane, isobutane, liquid or gasifiable hydrocarbons and combinations thereof is converted, under the action of plasma, with at least one further starting material, to at least one product, or
• a hydrocarbon-containing starting material selected from the group consisting of natural gas, pyrolysis gas, biogas, methane, ethane, propane, butane, isobutane, liquid or gasifiable hydrocarbons and combinations thereof is converted in a first method step, under the action of plasma, to one or more intermediate product(s) which, in at least one subsequent method step, are converted to a reaction product,
• wherein the hydrocarbon(s) of the hydrocarbon-containing material consist of hydrogen and carbon, wherein the conversion under the action of plasma is effected in a plasma reactor, with the plasma gas present in the plasma reactor, which plasma gas contains the products or intermediate product(s) produced, and wherein
• (i) the product(s) or intermediate product(s) produced by plasma-catalytic conversion is/are introduced into a scrubbing liquid containing at least one catalyst, with at least one of these products or intermediate products being converted in the scrubbing liquid by the catalyst;
• or
• (ii) the starting materials introduced into the plasma reactor are conveyed by means of a liquid jet pump located downstream of the plasma reactor and the products or intermediate products are continuously removed from the plasma reactor by the liquid jet pump, wherein a liquid which contains at least one catalyst is/are used as a motive fluid of the liquid jet pump for further conversion of the products or intermediate products obtained.
