In this process, glycerol is dehydrated by means of a new catalyst that supports acids/bases to produce acrolein, which is then oxidized to acrylic acid using the company's proprietary oxidation catalyst. In the traditional route, acrolein was generated from propylene oxide through two process steps.
Catalytic synthesis company is currently optimizing the glycerol dehydration step according to the laboratory scale, the goal is to make the production of acrolein yield of 80 ~ 90mol%, the company will also obtain new energy industry technology and technology development organizations (Kawasaki, Japan) support in From 2009 to 2010, it invested 2 billion yen (20 million US dollars) to build medium-sized devices. The company plans to complete small-scale and medium-sized device designs in 2009 and set up and commissioned medium-sized devices at its Himeji production site in 2010 to validate glycerol production. The basic design plan for commercial installations is planned for 2011 and commercial production will be achieved by 2012.
Japan has developed acrylic acid from glycerol
Japan Catalytics announced at the end of October 2009 that it is developing a process to make acrylic acid directly from glycerol, a by-product of biodiesel production. In 2007, Japan Catalytics Co., Ltd. transferred its technology from the Japan Institute of Earth Innovation Technology, and has verified that it can produce BDF and 98% pure glycerol from plant-based biomass such as palm oil. The company has produced 20 tons/year fatty acid methyl ester (FAME) at the Tsukuba Research Laboratory with a yield of 99 mol% and 2 tons/year of glycerol. Now, the company has planned to use its glycerin to make acrylic, the precursor of the production of plastics, coatings, adhesives and elastomers.
