Bayer materials technology: carbon dioxide replaces oil to produce polyurethane
Bayer materials technology: II. Replace oil to produce polyurethane with antifreeze oxidized carbon
April 17, 2015
[China coating information] Bayer materials technology representatives and held a round table discussion at the 2015 international polyurethane Exhibition (UTECH Europe synthetic resin lotion exterior wall coating gb/t 9755 ⑵ 001), which solved the problem of waste polyurethane incineration
Christoph gurtler, the catalyst project director of the polyurethane Department of Bayer materials technology, said: "incineration is the most economical way to solve the waste and waste, because compared with the production of new materials, recycling will produce greater carbon emissions. The European Union reach regulation expressly prohibits the chemicals used in the production of polyurethane. Compared with simple incineration, the recycling process will consume more energy." He also said that the chemical industry can also use the energy generated by burning carbon dioxide
Bayer materials technology advocates giving priority to the use of heat recovery to incinerate waste polyurethane products, so as to promote the recycling of polyurethane rigid foam
Herma, head of polyurethane business department (Europe, Middle East, Africa and Latin America), manually controls the experimental process NN according to the dial reading, and there are many reasons. Josef dorholt said that the company expects carbon dioxide to replace oil as production raw material. "We have been successful in this area and the project is progressing."
Ulrich Liman, head of polyurethane innovation department, said: "we hope that we will no longer use oil to produce polyurethane products in the coming years. At present, we have relevant research and understanding, but we have no industrial production method."
liman also said: "using carbon dioxide to replace oil to produce polyurethane products is more in line with sustainable development. We should not rely on oil because we can not control its price and are vulnerable to price fluctuations."
