Abstract: A chemical reactor has a battery of contact tubes that are individually filled with different combinations of pre-formed catalyst rings. The different types of ring are held in pre-packed sizes. In a process to fill the tubes, the tubes are first filled with pre-packed rings. A number of rings are then removed manually as required from each tube to leave the requisite content. The catalyst rings are introduced in pre-packed quantities of from 50 g to 5 kg. In the subsequent reaction, individual rings expand by between 1 and 20 mm. Each tube has three or more sections. The ratio of the contact tube diameter to catalyst length is 2:1 - 20:1.

Abstract: A PROCESS FOR THE CATALYTIC GAS-PHASE OXIDATION OF ACROLEIN TO ACRYLIC ACID IN A MULTIPLE CONTACT TUBE FIXED-BED REACTOR THROUGH WHOSE SPACE SURROUNDING THE CONTACT TUBES ONLY ONE HEAT-EXCHANGE MEDIUM CIRCUIT IS PASSED, AT ELEVATED TEMPERATURE ON CATALYTICALLY ACTIVE MULTIMETAL OXIDES WITH AN ACROLEIN CONVERSION FOR A SINGLE PASS OF > 95 MOLAND AN ACRYLIC ACID FORMATION SELECTIV-ITY OF > 90 MOL , WHICH COMPRISES FIRSTLY PASSING THE HEAT-EXCHANGE MEDIUM THROUGH THE MULTIPLE CONTACT TUBE FIXED-BED REACTOR LONGITUDINALLY, CONSIDERED O.VER THE REACTION CONTAINER AS A WHOLE, TO THE CONTACT TUBES IN COCURRENT TO THE REACTION-GAS MIXTURE AND SECONDLY SUPERPOSING A TRANSVERSE FLOW WITHIN THE REACTION CONTAINER BY MEANS OF AN ARRANGEMENT OF SUCCESSIVE BAFFLES ALONG THE CONTACT TUBES WHICH LEAVES PASSAGE CROSS SECTIONS FREE, SO AS TO GIVE A MEANDROUS FLOW OF THE HEAT-EXCHANGE MEDIUM, SEEN) IN LONGITUDINAL SECTION THROUGH THE CONTACT TUBE BUNDLE, AND SETTING THE FLOW RATE OF THE CIRCULATED HEAT-EXCHANGE MEDIUM SO THAT ITS TEMPERATURE RISES BY FROM 2 TO L0?C BETWEEN THE POINT OF ENTRY INTO THE REACTOR AND THE POINT OF EXIT OUT OF THE REACTOR.

Abstract: "processo para a preparação de pelo menos um composto orgânico". são preparados compostos orgânicos através de oxidação em fase gasosa parcial heterogeneamente catalisada de compostos precursores através de um processo, no qual uma porção da mistura de partida da reação é conduzida a partir de uma baixa pressao inicial a uma pressão final mais alta por meio de um compressor radial.

Abstract: processo para controlar uma coluna de lavagem hidráulica. é divulgado um método para operar uma coluna de lavagem hidráulica, no qual a posição da frente de lavagem na coluna de lavagem é determinada por meio da vazão do líquido de controle conduzido para dentro da coluna de lavagem e/ou por meio da vazão da suspensão conduzida para dentro da coluna de lavagem, e a vazão é definida com o auxílio da diferença de pressão entre pontos na zona de suspensão localizada a montante da frente de lavagem e pontos na zona que se estende da frente de lavagem até a extremidade do leito de cristais na coluna.
