Low capital cost due to highly active catalyst
Low-cost catalyst
High-purity process
Low OPEX
Over 40 years of operating experience and technology improvement
How It Works
The chemistry of converting BDO to THF is an acid-catalyzed ring closure of BDO to produce THF and by-product water.


In the past, the KTS technology for the production of THF utilized Sulfuric Acid as the acid catalyst. We have developed and are commercializing a new process that utilizes a strong acid resin as the catalyst which eliminates the need for high-alloy reactors and exchanges, generates less waste, and has a smaller environmental footprint. While high-purity BDO is one requirement for producing high-quality THF for use in the PTMEG market, another requirement is extremely low levels of color forming unsaturates. The KTS process incorporates a hydrogenation step into the refining process to ensure these color-forming impurities are converted and/or removed from the product.
