UCLA chemists use MRI to peek at temperatures of gases inside catalytic reactors

UCLA chemists for the first time have employed magnetic resonance imaging (MRI) — a technique normally reserved for medical clinicians peering inside the human body — to better measure the temperature of gases inside a catalytic reactor. 

The research, a major step toward bridging the gap between laboratory studies and industrial catalysis, could help improve the design and environmental impact of catalytic reactors, including tiny "lab-on-a-chip" devices, which are used in the manufacture of pharmaceuticals and other chemical products. 

A continuous-flow micro-reactor packed with metal-organic framework catalyst promotes the conversion of propylene into propane. UCLA researchers measured the heat generated in the reaction without perturbing the flow by using an MRI technique. Thermometry is achieved by probing motional averaging effects in a magnetic-field gradient. (Credit: UCLA/Nanette Jarenwattananon, Yuebiao Zhang, Louis Bouchard)
