Preparation of the support material (carrier)
The DMR flash dryer is very suitable for producing catalyst carriers from slurries. And it has a major advantage compared to conventional flash dryers, because the DMR is much more energy efficient. Support materials are conventionally dried using a spray dryer, which needs to be fed in slurry form. The DMR flash dryer however, can be fed with slurries but also with filter cakes or pastes. Therefore a much more energy efficient, mechanical dewatering process can be used before thermal drying.
Impregnation of carriers with actives
Nauta mixers and vacuum dryers are very suitable for the impregnation of catalyst carriers with active groups. They provide a gentle mixing and drying process, necessary because the relative size of the catalyst could determine activity as well as selectivity. By adjusting temperature and/or pressure during the process, any type of impregnation can be achieved.
The carrier is impregnated by addition of the solution in the mixer just in front of the agitator, making sure that the active ingredient is evenly distributed on the support. After addition, the product can be dried and the solvent can be recovered.
After addition of the actives the material can also be calcined or dried using the Nauta vacuum dryer, either under inert atmosphere or, depending on the grade after drying, oxygen levels can be slowly increased at certain temperatures to passivate the metals on the carrier.
MILLING & COMPACTION
Besides mixers and dryers, the Hosokawa Group also offers milling and compaction equipment, suitable for the production of catalysts.
TESTING & PROCESS DEVELOPMENT
Our test and process development centre in the Netherlands offers unique possibilities for testing your product to determine the most efficient process, system or plant prior to final design. We can provide laboratory-level as well as production-sized trials.
Whether you wish to test a single machine or a complete powder processing system, the same skilled and experienced staff are here to help ensure that your requirements are met, and that you are entirely satisfied with the results.
We offer process equipment and technologies from individual units to large scale bespoke system solutions. Our principle is to deliver high performance yet affordable solutions that meet our customers' demands and long term challenges.
