Abstract
Carbon particles non-uniformly and non-continuously coated with polytetrafluoroethylene (PTFE) are produced by adding a PTFE emulsion to the carbon particles at a rate of less than approximately 100 ml/100 grams. The result is a mixture of PTFE coated carbon particles, some having a higher weight percent PTFE resin thereon and others having a lower weight percent PTFE resin thereon. Such a mixture of non-uniformly coated particles gives improved reaction efficiency when used as a solid catalyst in a packed bed tower reactor through which fluid reactants are flowed.
