摘要： PROBLEM TO BE SOLVED: To provide a reactor apparatus and a method for treating fluid material in which temperature is measured in the representative conditions in the tubular reactors. SOLUTION: The reactor apparatus comprises both a tubular reactor equipped with a temperature measuring unit and a tubular reactor unequipped with the temperature measuring unit. The tubular reactors are set up so that the mass of solid particles to be introduced is directly proportional to the free cross-sectional area of the respective tubular reactors and flow resistance or pressure drop in the tubular reactors, and accordingly average rectilinear velocity are identical when gas flow rate being proportional to the free cross-sectional area is conducted. Concretely, the above- mentioned pressure drop is adjusted by fines fraction of the solid particles in accordance with the following formula. mfines =mtot (Pm -PI)/(P2 -P1 ) (in formula, mfines denotes mass of fines fraction. mtot denotes total mass of solid particle and fines fraction. Pm denotes average pressure drop in tubular reactor unequipped with temperature measuring unit. P1 denotes pressure drop in tubular reactor equipped with temperature measuring unit in the case of filling solid particles. P2 denotes pressure drop in tubular reactor which is equipped with temperature measuring unit and is filled with fines fraction).

摘要： In the sepn. of (meth)acrylic acid (I) from mixts. contg. (I) as main prod. and lower aldehydes as by-prods. by rectification in a column with a distn. zone and a concn. zone, the mixt. is not supplied to the column directly. Instead, it is passed to a heated dwell vessel connected to the concn. zone, in which the mixt. is kept boiling, and the sump liquid from this vessel is fed to the column.

摘要： 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 mol % and an acrylic acid formation selectivity of >/=90 mol %, which comprises firstly passing the heat-exchange medium through the multiple contact tube fixed-bed reactor longitudinally, considered over 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 DEG to 10 DEG C. between the point of entry into the reactor and the point of exit out of the reactor.

摘要： A gas-phase mixture of propene and oxygen is catalytically oxidized by passing a reactant gas mixture comprising propene and oxygen through a plurality of catalyst containing contact tubes in a fixed bed reactor and simultaneously passing only one heat-exchange medium at elevated temperature over the exterior surfaces of the contact tubes in a longitudinal flow pattern which is cocurrent with the direction of flow of the reactants through said tube; simultaneously superposing a transverse flow on said longitudinal flow of heat exchange medium by means of an arrangement of successive baffles along the contact tubes which leave passage cross-sections free, thereby resulting in a meandrous flow of the heat-exchange medium through the reactor and setting the flow rate of said heat-exchange medium so that its temperature between the point of entry of the medium into the reactor and its point of exit increases by 2 DEG to 10 DEG C.; and obtaining product acrolein at a selectivity >/=85 mol % from the reactor at a single pass propene conversion >/=90 mol %.
