Introduction to Research

The research in this chair is focused on the development of environmentally benign technology based on several new conversion methods. The current research activities cover the following topics. The staff also manages the chair of Environmentally Benign Chemical Processing, Department of Technology and Ecology, School of Global Environmental Studies.

1. Development of new biomass conversion methods

Biomass is a promising resource as a highly condensed energy media of solar energy. From this viewpoint, several new methods are developed to recover chemicals, methane, and hydrogen from biomass by supplying waste heat.

  1. Liquid phase degradation of wet biomass under mild conditions.
  2. New pyrolysis method for wood biomass.
  3. Kinetic model of biomass pyrolysis and gasification.

2. Development of new environmental catalysts

The harmful pollutants must be destructed completely. Several new catalysts are developed to remove efficiently the pollutants as follows:

  1. Production of porous FeOOH from waste FeCl3 and its application for the removal of F and PO43- ions.
  2. Development of new catalysts for removing VOC and CO at low temperatures.
  3. Development of an inorganic/organic hybrid membrane for the removal of CO2.

3. Design of ecological industry

A new concept for ecological processing is proposed. The concept is to produce valuable materials and energy by combining waste materials and waste heats. To build up an ecological industry network based on the proposed technologies, the following items are investigated.

  1. Production of energy and materials through the co-production of biomass with various metals.
  2. Development of pre-carbonized process for the separation of waste mixture.
  3. A new evaluation method for environmental impacts associated with technology.

4. Development of various micro reactors - Basic research of micro chemical engineering -

Novel devices available for green chemistry are required to produce valuable materials with low CO2 emission. Various micro reactors with new concepts are proposed and their performances are investigated as follows:

  1. Development of various micromixers and microreactors and basic research for micro reactor system. (Collaboration by several Kozas
  2. Production of nano-particle by several micro reactors.
  3. Development of compact reformer for fuel cell.
  4. Development of micro device and operation method for super-critical fluid.
