Fischer Tropsch wax is a synthetic wax produced by the polymerization of carbon monoxide under high pressure, a technology used in the emerging natural Gas to Liquid (GTL) projects. The hydrocarbon product of FT reaction is distilled to separate the mix into fuels products and waxes with melting points ranging from about 45 – 106ºC.
