“…Recently, a microreactor manufactured by direct metal laser sintering has demonstrated 500 sccm of methane conversion by absorbing solar radiation as a heat source instead of a carbonbased energy source. 125 Research to reduce carbon emissions is much less active in distributed SMR processes than in centralized ones because carbon emissions in small systems are not as fatal as they are in large systems. However, more effort will need to be devoted to this area for the widespread adoption of small-scale SMR technologies in the long run.…”

Researchers from Université de Sherbrooke have developed a new generation of high efficiency Solar Microreactor to harvest the power of the sun for hydrogen production. This paper presents the architecture, the manufacturing and assembly of this highly integrated system that incorporates in a monolithic block the heat exchangers, catalytic bed and manifolds. Miniaturization of the system provides high heat and mass transfer capabilities and can easily be assembled into a matrix to cover the focal point of any Solar Concentrator. Performances of the Microreactor is first investigated in a laboratory using a high flux solar simulator to plot an efficiency map for a dry methane reforming test under different combinations of reagent mass flow and reaction temperatures. This map is then used as a benchmark for outside tests in order to evaluate the real-condition efficiency of such microreactor matrix. Outside tests were performed with the Université de Sherbrooke’s 100 kW SpaceWatt solar concentrator. It is estimated that the efficiency reaches up to 54 % for the matrix of reactor in real condition operation for an estimated heat flux of 520 kW/m2 compared to the measured value of 71% in laboratory conditions for a single reactor with a heat flux of 800 kW/m2.

Robotic actuators such as geared MR actuators must improve their torque capacities and reduce their size to increase system integration density. MR clutches are at the heart of geared MR actuators and conventional machining is a major hurdle to downsizing because it requires having close tolerance for machining and assembling a large number of small parts. This paper studies the potential of nested 3D printed MR clutches to improve the torque density of geared MR actuators at small scales. Nested 3D printed MR clutches are multi-disk MR clutches where the rotor and stator are fabricated simultaneously on a single 3D print. A prototype is designed, built, tested and compared to similar conventionally made MR clutches. The prototype weighs 84 g and can transmit a maximum torque of 0.88 N.m. The fabrication process is fast and simple, and the performance levels well surpass those of comparable machined MR clutches. The manufactured prototype doubles the torque density and multiply respectively by 4 and by 10 the torque-to-inertia and torque-to-viscosity ratios compared to equivalent machined MR clutches. Results show that nested 3D printing of MR clutches is an effective manufacturing process and opens the door to a new generation of high-performance mechanical transducer.
