This invention relates to a process for conducting a hydrocracking or a hydrotreating process in a microchannel reactor. This invention also relates to a process and apparatus for flowing a vapor and liquid into a plurality of microchannels in a microchannel processing unit.

This invention relates to a process and an apparatus for conducting simultaneous endothermic and exothermic reactions in a microchannel reactor. A start-up procedure for the microchannel reactor is disclosed.

An integrated microchannel reactor and heat exchanger comprising: (a) a waveform sandwiched between opposing shim sheets and mounted to the shim sheets to form a series of microchannels, where each microchannel includes a pair of substantially straight side walls, and a top wall formed by at least one of the opposing shim sheets, and (b) a first set of microchannels in thermal communication with the waveform, where the waveform has an aspect ratio greater than two.

Fluidic systems, modules, and associated methods are generally described. In some embodiments, a fluidic system comprises a module which is configured such that fluid may flow therethrough with a relatively uniform time-averaged linear flow rate (i.e., the time-averaged flow rate that is perpendicular to the transverse cross-sectional area) and/or time-averaged flux across the transverse cross-sectional area of the module. Advantageously, such modules may behave in a way such that the time-averaged linear flow rate and/or time-averaged flux exhibits minimal or no dependence on the transverse cross-sectional area thereof. This may allow for modules to be scaled-up in a relatively facile manner by merely increasing the transverse cross-sectional area, which may eliminate or substantially reduce the need for other components of the module to be redesigned upon scale-up. In some embodiments, modules may be scaled-up in a manner that requires no or minimal chemical process adjustments.

A continuous-flow preparation method for an amino alcohol compound using a micro-reaction system. The micro-reaction system includes a feed pump, a micromixer, a microchannel reactor, and a back pressure valve. An aldehyde compound and an amine compound are simultaneously fed to the micro-mixer for mixing to obtain a mixed solution. The mixed solution is directly fed to the micro-channel reactor and undergoes an addition reaction. The reaction mixture is collected, and subjected to concentration, separation and purification to obtain the desired amino alcohol compound.

A chemical flow reactor comprising: a housing having an inlet and an outlet; at least one heat exchange pipe extending through the interior of the housing; a space defined between the interior surface of the housing and the outer surface of Gas Flow the at least one pipe, said space being in fluid communication with the inlet and the outlet; and a plurality of plates stacked within said space forming a stacked plate assembly between the inlet and the outlet, each plate comprising at least one hole through which the at least one pipe extends such that the at least one pipe extends through the stacked plate assembly. An active chemical, such as a catalyst, is disposed on each plate.

The present invention relates to a continuous flow process for synthesis of acephate and its intermediates. The present invention more particularly relates to synthesis of acephate and its intermediates in a microreactor system.
