摘要： Provided is a method for producing alcohols by an olefin hydration reaction using a heteropolyacid catalyst, wherein the catalyst can be stably used on a long-term basis. The temperature difference within the catalyst layer in the olefin hydration reaction using a heteropolyacid catalyst is made less than or equal to a certain value. Specifically, in a method for producing alcohols in which a gas-phase hydration reaction is carried out using a solid acid catalyst that supports a heteropolyacid acid or salt thereof and supplying water and C2-C5 olefin to a reactor, the temperature difference within the catalyst layer in the reactor is established at less than or equal to 6° C.

摘要： The present invention relates to a multi tubular metal hydride reactor with integrated buffer storage. The present invention more particularly relates to metal hydride reactor with integrated buffer storage configuration with 7 tubes with metal hydride and 4 longitudinal fines attached to 5 concentric rings, the metal hydride tubes are supported by means of 4 baffles, having a total 50 kg LaNis distributed equally among the tubes and water as heat transfer fluid flows across the shell for heat transfer. The metal hydride reversibly stores 680 grams of hydrogen amounting to 1.34 wt. % of gravimetric capacity of metal hydride and equivalent energy storage of 10.4 MJ. In case of absorption, when the flow rate selected was 20 LPM the absorption time for 90% reaction completion was observed to be 1286 s (21.4 min) at 30 bar H2 supply pressure. In case of desorption studies, it was observed that the varying flow rate from 15 to 25 LPM has negligible effect on hydrogen desorption hence 15 LPM was selected as a flow rate for further desorption experiments. Further increasing HTF temperature from 60° ° C. to 80° C. improves the performance significantly.

摘要： A method for producing a target compound includes distributing a feed mixture at a temperature in a first temperature range to a plurality of parallel reaction tubes of a shell-and-tube reactor, and subjecting the feed mixture in first tube sections of the reaction tubes to heating to a temperature in a second temperature range and in second tube sections of the reaction tubes arranged downstream of the first tube sections to oxidative catalytic conversion using one or more catalysts. A gas mixture flowing out of the second tube sections is brought into contact in third tube sections arranged downstream of the second tube sections with a catalyst which has a volumetric activity below the highest volumetric activity of the one or the plurality of catalysts arranged in the second tube sections. A gas mixture from the third tube sections is withdrawn from the shell-and-tube reactor without further catalytic conversion.

摘要： The invention relates to a reformer furnace for catalytic reforming of a carbon-containing input material with steam. The reformer furnace has a steel construction which serves as a framework for a refractory lining and for the fastening of burners, reformer tubes and supply and discharge lines. The burners and reformer tubes are arranged in rows, parallel to one another and in alternating fashion. The steel construction includes a plurality of main carrier units, wherein each main carrier unit has at least two vertically extending supports and a horizontally extending main carrier which connects the supports. This type of steel construction makes it possible to achieve uniform spacing of the reformer tubes and burners over the entire reformer furnace. This results in advantages in terms of the maximum operating temperature of the reformer tubes, thereby extending their service life.
