The invention relates to an hydrolysis vessel (200) used during amidification step of acetone cyanohydrin (ACH), in the industrial process for production of a methyl methacrylate (MMA) or methacrylic acid (MAA). The hydrolysis vessel (200) is used for hydrolyzing acetone cyanohydrine with sulfuric acid to produce a mixture comprising -sulfatoisobutyramide (SIBAM). It comprises at least one cooling system (212; 244) on its internal annular periphery area and it is divided into at least two stages, preferably three, along its vertical wall, each stage (S1 to S3) comprising a ACH feeding inlet (201, 202, 203). Such vessel allows controlling both homogeneity and temperature of the mixture, and thus obtaining a high yield for the hydrolyzing reaction in very safe conditions.

A reaction system and method for preparing compounds or intermediates from solid reactant materials is provided. In a specific aspect, a reaction system and methods are provided for preparation of boron-containing precursor compounds useful as precursors for ion implantation of boron in substrates. In another specific aspect, a reactor system and methods are provided for manufacture of boron precursors such as B.sub.2F.sub.4.

A reactor comprising a thermal barrier surrounding a combustion zone. The reactor further comprises a cooling jacket inner wall and a binder disposed between the cooling jacket inner wall and the thermal barrier, and a cooling jacket outer wall, wherein the cooling jacket inner wall and the cooling jacket outer wall define a cooling channel. The reactor further comprises an outer reactor wall disposed over the cooling jacket outer wall, wherein the outer reactor wall is impermeable and is configured to contain high pressure gas within the reactor.

This disclosure relates to weldments useful as heat transfer tubes in refinery processes dealing with gas phase hydrocarbon process streams at high temperatures. This disclosure also relates to tubes that are useful in refinery processes dealing with gas phase hydrocarbon process streams at high temperatures. The weldments include a tubular member and at least one mixing element. The tubular member comprises an aluminum-containing alloy. The mixing element comprises an aluminum-containing alloy. The mixing element's aluminum-containing alloy can be the same as or different from the tubular member's aluminum-containing alloy. Other aspects of the disclosure relate to refinery processes dealing with gas phase hydrocarbon process streams at high temperatures which include such weldments.

In various embodiments, a microreactor features a corrosion-resistant microchannel network encased within a thermally conductive matrix material that may define therewithin one or more hollow heat-exchange conduits.

A reactor system for high temperature reactions of reactants includes at least one reactant containing carbon. The reactor includes a reactor, a liquid media disposed within the reactor, and a solid carbon reaction product. The liquid media does not react irreversibly with the reactant to form products, and the liquid media wets at least a portion of a surface within the reactor. The solid carbon reaction product does not contact at least the portion of the surface within the reactor where the liquid media wets the portion of the surface within the reactor.

Reactor (1) for catalytic chemical reactions, comprising: a partially open outer vessel (2) comprising a manhole (6) for accessing to the interior, and at least one internal wall (5) comprising a plurality of panels (5.1, 5.2, . . . 5.n) assembled inside the vessel (2) so as to form said wall (5); the panels are flexible and deformable so that they may be inserted through said manhole (6), and the resulting wall (5) is not self-supporting and rests against a load-bearing wall (7) of the reactor.
