Research Topics

The production processes of the functional materials by chemical vapor deposition (CVD) and of mono-disperse inorganic particles by continuous precipitation as well as the electrochemical processes including the polymer electrolyte fuel cell (PEFC) and the electric double layer capacitor (EDLC) are being investigated. Kinetic analysis of these reactions as well as the development of new processes are being carried out.

Research Topics

We are working on the development of effective utilization of coal. The method being investigated extracts from coals, which is still abundant all over the globe and quite cheap, the components that can be used as not only clean fuel but also raw materials for valuable materials. Production of high performance activated carbons from biomass waste is also being investigated.

Introduction to Research

The research at this chair is focused on modeling and development of various chemical reaction processes including materials production processes and electrochemical processes. Current research topics are as follows:

1. Development of new functional materials and materials production processes

Material research such as development of functional materials are being carried out.  The processes for materials production are also our research targets.  Specific projects in this area include:

  1. Production of silica film by plasma chemical vapor deposition,
  2. Kinetic analysis of carbon deposition from polyaromatic hydrocarbons in chemical plants, and
  3. Development of an alumina coating process using a novel reactant.

2. Chemical reaction engineering modeling of various reaction processes

We are also applying chemical reaction engineering to new processes as follows:

  1. Modeling of polymer electrolyte hydrogen fuel cell (PEFC).
  2. Modeling of electric double layer capacitor.

3. Development of new conversion processes of coal and other carbonaceous resources in novel reaction schemes

Innovative energy reaction processes are required for attaining effective and clean conversion of coal and other carbonaceous resources into energy and valuable chemicals.  We have developed several new coal conversion methods and are continuing to improve the coal conversion and liquid yield.  Some new conversion processes are also being developed.  Specific projects in this area include:

  1. Fractionation of coal by the extraction of coal at elevated temperature and pressure,
  2. Investigation of reduction mechanism of iron ore in iron ore/carbon composite, and
  3. Development of a new power generation process utilizing liquid-phase redox reactions between carbonaceous resources and inorganic chemicals.
