Polymer-Ceramic Composite Membranes for Water Removal in Membrane Reactors.

Methanol can be obtained through CO hydrogenation in a membrane reactor with higher yield or lower pressure than in a conventional packed bed reactor. In this study, we explore a new kind of membrane with the potential suitability for such membrane reactors. Silicone-ceramic composite membranes are synthetized and characterized for their capability to selectively remove water from a mixture containing hydrogen, CO, and water at temperatures typical for methanol synthesis.

Infrared sensor-based temperature control for domestic induction cooktops.

In this paper, a precise real-time temperature control system based on infrared (IR) thermometry for domestic induction cooking is presented. The temperature in the vessel constitutes the control variable of the closed-loop power control system implemented in a commercial induction cooker. A proportional-integral controller is applied to establish the output power level in order to reach the target temperature.
