The problems associated with energy, resources and the environment are the major issues of the 21st century not only in Japan, but throughout the world. To address these issues, research is being carried out at the Matsukata Laboratory into the science and engineering of catalytic chemistry, membrane separation engineering and energy chemistry. In particular, effort has focused on research into the synthesis and catalysis of micro/meso-porous materials, their use as separation membranes, and the development of processes for making effective use of coal and waste materials.
■ Compared to traditional processes that make use of phase changes such as cryogenic separation, the separation process through a zeolite membrane enables energy savings. As shown in Fig. 1, zeolite has a separation function that makes use of differences in molecular size and adsorptive power. We were the first in the world to develop an inorganic membrane that achieved separation at a molecular level, and we have continued our research in this area. We developed a practical method of forming a thin zeolite membrane on a porous support. We also developed a unique characterization method of evaluating the structure of their inorganic porous membranes and separation performance, a part of which we are trying to turn into products.
We are aiming to find industrial applications for our separation membranes, and as for dehydration membranes for isopropyl alcohol and acetic acid, we have launched an industry-academia collaboration project. Regarding the dehydration membrane for isopropyl alcohol, we ran performance evaluation tests using actual solutions on-site at a factory between 2012 and 2014. We are trying to expand application of this separation technology for use on a variety of other mixtures (gases and liquids). In addition, we are trying to apply it to membrane reactors that combine reactions with separation.
We were the first in the world to develop an inorganic membrane that achieved separation at a molecular level. We have technology for forming zeolite membranes, and methods of evaluating their structures.
