Currently, nearly all biodiesel is produced using liquid acid and/or base catalysts. Liquid catalysts become part of the waste stream and contaminate the glycerin byproduct. The Point Hope Energy solid catalyst stays in the reactor, yielding a much more valuable high-purity glycerin. Since the solid catalyst converts both triglycerides and free fatty acids, the Point Hope Energy technology can process a broad range of waste and recylced oil feedstocks.
