The molecular sieve adsorbent is utilized immediately before a cryogenic process to remove water so that ice is not created during the process. However, inherent in the process is the fact that the hydrocarbon feed stream contains unsaturated hydrocarbons, such as alkenes, which are very reactive. These unsaturated hydrocarbons tend to form ...
