Abstract:
The metal concentration in a liquid hydrocarbon stream can be reduced to no more than 0. 1 parts per billion by contacting the stream sequentially with a cation exchange resin and a silver-impregnated zeolitic molecular sieve, preferably in that order. The method is particularly useful for removal of mercury and antimony from liquified petroleum gas.
