Housing-encased micro reactor

Housing-encased Single-platelet and Multi-platelet Stack Micro Reactors... 

One of the most frequently used micro reactor types relies on the use of micro-structured platelets with multiple parallel channels, typically manufactured by methods other than routinely used for chip processing, encased in a housing [3,4, 12, 13, 18, 28-39]. If more than one platelet is used, which is usually done to increase throughput, a stack-like arrangement is preferred for parallel feed. Such stacks are either welded directly from the outside [29, 30], are encompassed by a cover [3,18, 31, 32, 37-39], have end caps with fluidic connectors [12,13, 33] or are inserted into a recess of a housing, which is typically composed of two parts [4, 28, 34-36, 40 1]. 

A complete reactor module was built, consisting of the actual micro reactor and an encasement that serves for temperature setting [28], The latter consists of two parts, a furnace for setting the high temperature in the reactor inlet collection zone and in the reaction zone and a cooler for the outlet collection zone. The micro reactor has a housing with standard tube connections. An electric furnace serves for heating, Temperatures can be measured in the furnace, at the furnace/micro reactor border and in the outlet collection zone. For thermal insulation, a 2 mm ceramic... 

Only a rough description of this micro reactor was given (Figure 5.10), not disclosing all details [20]. A pair of iron plates coated with Pd catalyst is inserted in disk-type holders. Such a supported micro channel device is encased in a housing. 

The micro reactor consisted of a pair of iron plates coated with Pd catalyst placed on disk-type polypropylene holders [20]. This micro channel device was encased in a stainless-steel housing. The thickness of the catalyst layer was approximately 5.0 pm 10 mg catalyst was deposited per plate, so giving 20 mg in total. The specific surface area of the catalyst was 3.6 0.4 m g ...
