    摘要： In a process for the preparation of methanol in parallel reactors, comprising the steps of (a) reacting carbon oxides and hydrogen in the presence of a methanol catalyst in a first methanol reactor to obtain a first methanol-containing effluent, (b) introducing and reacting unconverted synthesis gas in a second methanol reactor in the presence of a methanol catalyst to obtain a second methanol-containing effluent, the first methanol reactor and the second methanol reactor being connected in parallel, (c) combining the first and second effluent, and (d) cooling and separating the combined and cooled effluent into a methanol-containing liquid phase and unconverted synthesis gas, the methanol catalyst in the first methanol reactor is indirectly cooled by boiling water and the methanol catalyst in the second methanol reactor is either directly or indirectly cooled by the unconverted synthesis gas prior to conversion into the second effluent.

    摘要： The invention relates to a backup column for a heat and/or material exchange between a liquid phase and a flowing gaseous phase in the counter flow thereto, wherein the backup column (1) comprises at least two sections (2a-2c) with a first layer (3a) having a high specific surface and a lower throughput capacity and a second layer (3b) arranged on top with a lower specific surface and a higher throughput capacity. According to the invention, the first layer (3a) of the sections (2a-2c) of the backup column (1) is designed for forming a backup zone and thus a spouting bed with pourable first fillers (4) with a high specific surface and a low throughput capacity and the second layer (3b) of said sections (2a-2c) is designed for forming a separating zone for the liquid phase with pourable second fillers (5) comprising a lower specific surface and a higher throughput capacity compared to the first fillers (4) of the first layer (3a).

    摘要： A method for forming packing for resin catalytic packed beds (12), comprising: providing elastic means (1) which are capable of compressing under the pressure applied by resin particles (11) which expand upon contact with a specific work substance, and have characteristics of elasticity and resiliency which are adapted for the expansion factor of the resin; preparing a packing constituted by a mixture of particles (11) of resin and of elastic means (1), mixed in proportions which are selected as a function of the degree of expansion; and loading the packing (5) so as to constitute an elastic catalytic packed bed (12) which is adapted to remain dimensionally stable following the expansion of the resin particles (11) and allow an easy flow of the substance through the catalytic packed bed (12). The packing thus formed comprises a mixture (5) of particles of resin, which can expand upon contact with a specific work substance and elastic means (1) adapted to compress under the pressure applied by the expanding particles and is constituted by proportions of particles (11) and elastic means (1) which are selected as a function of the resin expansion factor.
