Abstract:
A microreactor for photoreactions includes a housing upper part, a lid plate made of a material that allows transmission of light, a flow path plate made of a material that suppresses light reflection and has a high thermal conductivity, and a housing lower part. Light is applied through a window of the housing upper part and the lid plate to a flow path of the flow path plate. The lid plate made of the material that allows transmission of light and the flow path plate made of the material that suppresses light reflection and has a high thermal conductivity are welded each other to form an integrated body.

Disclosed herein are methods for dehydrogenation of alkanes to olefins by co-injecting the alkane feed with hydrogen. The present methods provide the improved feed conversion, desired product selectivity, total olefins in product stream, and lower catalyst deactivation rate.
Abstract:
Emulsion breaking and phase separation is achieved by droplet adhesion. An emulsion breaking device includes a channel having distinct adjacent zones with distinctly different surface wettability characteristics, namely, solvophilic and solvophobic surfaces. The device is positioned such that the upstream portion of the device is configured to be wetted by the continuous phase of the emulsion, and the downstream portion of the device is configured to be wetted by the dispersed phase of the emulsion. As the emulsion flows from the upstream zone to the downstream zone, the change in surface wettability characteristics promotes adhesion of the dispersed phase as the dispersed phase wets the surface of the downstream portion of the channel, which results in breaking of the emulsion. Subsequent collection of the broken emulsion in a collection vessel results in separation of the disparate phases to facilitate their recapture and recycling.
