Reactor Equipment

Our laboratory contains a scale-up facility with high-pressure reactors ranging from 5 mL to 20 L in volume with most pretreatment and enzyme mimetic work done in sandbath controlled 45 mL stainless steel tubular reactors. Instrument capabilities include liquid chromatographs (Waters, Ranin, and LDC, all with auto-injectors) for sugar, protein, and fermentation product analysis. Compositional analysis of the DDGS and other fibers is in a laboratory set up to follow the NREL standard laboratory procedures and has handled all previous samples on related projects. LORRE facilities include wet-bench facilities, molecular biology laboratories, fermentors up to 20 L, incubator-shakers, freezedriers, and cold sample storage. The Agricultural and Biological Engineering Department has a well-equipped machine shop capable of fabricating high-pressure fittings as needed for the research. The Engineering Computer Network of the Schools of Engineering at Purdue University provides the capabilities required for carrying out modeling and data analysis.


  • High Pressure Reactors: 300 mL and 20 L Autoclave Company high pressure reactors; 2 L Parr high pressure reactor for carrying out processing of biomass materials.
  • Steam Generators: Small and large generators capable of generating up to 50 psig and 300-psig steam, respectively.
  • Size Attrition Equipment: Laboratory Wiley mill, large-scale refiner (a device that shreds cellulosic materials).
  • Sand Baths: Tecaml laboratory scale (approximately 4 L volume) for carrying out high temperature reactions (up to 260 C).
  • Padder: Atlas Laboratory wringer for derivatizing textile fabrics and fibers (threads).
  • Furnace: Rapid temperature type high temperature furnace.
