ABSTRACT:
A method is provided for high temperature conversion of mercutry-containing hydrocarbon feedstocks to produce a product stream with a negligible mercury level and to protect cryogenic heat exchangers from mercury damage. The feed is treated with adsorbent at high temperatures to remove up to 99% of the mercury. After high temperature conversion, the product stream is treated over a second adsorbent composition to remove any residual mercury and water before the product is cooled and collected.
