Abstract: 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 A gas mixture from the third tube sections is withdrawn from the shell-and-tube reactor without further catalytic conversion.

Abstract: A method for producing a target compound, includes distributing feed mixture at a temperature in a first temperature range to a plurality of parallel reaction tubes of a shell-and-tube reactor. The method further includes 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 arranged in the second tube sections. The heating is performed, at least in part, using a catalyst arranged in the first tube sections and having a light-off temperature in the first temperature range.

Abstract: A process for producing a target compound includes forming a feed mixture containing at least one reactant compound. The feed mixture is distributed to parallel reaction tubes of one or more shell-and-tube reactors and subjected to oxidative catalytic conversion in the reaction tubes. Steam is added to the feed mixture in an amount such that a steam fraction of the feed mixture is 5 to 95 vol %, oxygen is added to the feed mixture in the form of a fluid containing at least 95 vol % oxygen, and the oxidative catalytic conversion is carried out using one or more catalysts containing the metals molybdenum, vanadium, niobium and optionally tellurium.

Abstract: A bullet-seating die for precisely loading a bullet into a cartridge case is disclosed. In embodiments, the bullet die comprises: a die body; a bullet-nose-alignment stem configured to engage and center a front end of a bullet within the die body before and after bullet seating begins; a bullet-seating-depth-adjustment screw adjustable to control seating depth of the bullet in a cartridge case; a bullet-seating collet configured to surround an ogival portion of the bullet that will engage the rifling when the loaded cartridge is fired; a bullet-seating collet bushing configured to positively center the bullet-seating collet in the die body; a case-shoulder-alignment bushing configured to positively center a front end of the cartridge case, the bullet-nose-alignment stem, and the bullet-seating collet bushing along the axis of the die body during bullet seating; and a case-base-alignment bushing configured to positively center a base of the cartridge case in the case-shoulder-alignment bushing.
