High-temperature reactor module

After preparation of newly developed membranes, high temperature permeation measurements were performed by VITO in Belgium. Steam treatment and membrane material characterisation were performed at SINTEF in Norway and reactor testing together with kinetic modelling of the reactor at IRC in France. The development of a high temperature test module for this reactor testing was the task of Velterop BV in the Netherlands. 

The modular HTR power plant is an energy source applicable for the co-generation of electricity, process steam or district heating. Standardized reactor units with power ratings of 200 MW (per module) and a core outlet temperature of 700 C can be combined to form power plants with any rating. The provision of process heat at a helium temperature up to 950 °C for coal gasification or for the aliuninum industry is also technically possible. The special safety features of small high temperature reactors are maintained for all applications.

Many applications of novolacs are found in the electronics industry. Examples include microchip module packaging, circuit board adhesives, and photoresists for microchip etching. These applications are very sensitive to trace metal contamination. Therefore the applicable novolacs have stringent metal-content specifications, often in the low ppb range. Low level restrictions may also be applied to free phenol, acid, moisture, and other monomers. There is often a strong interaction between the monomers and catalysts chosen and attainment of low metals levels. These requirements, in combination with the high temperature requirements mentioned above, often dictate special materials be used for reactor vessel construction. Whereas many resoles can be processed in mild steel reactors, novolacs require special alloys (e.g. Inconel ), titanium, or glass for contact surfaces. These materials are very expensive and most have associated maintenance problems as well. 

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...
