Abstract: The invention relates to an apparatus arranged within a gas flow system, said apparatus comprising a matrix structure composed of a plurality of solid elements being arranged singularly or in groups. The gas flow system comprises a plurality of voids in-between said solid elements. The matrix structure allows gas to propagate within said matrix structure, and the matrix structure is intended for changing the chemical composition of said gas having passed through the system. The change in chemical composition either takes place during one or more of the following processes: one or more chemical reactions promoted by catalytic coating of said elements, promoted mixing of different phases of components of said gas, or phase change by fluid drops evaporating or solid particles changing phase, or takes place by the matrix structure having a degree of open structure of said matrix structure for allowing the gas to flow along an overall flow pattern being a not-truly 3-dimensional flow pattern.
