Disclosed in certain embodiments are methods of removing water from a gas feed stream comprising hydrocarbons and water during an adsorption step of an adsorption cycle.

Disclosed is a heavy metal adsorbing mixture that sequesters heavy metals such as lead from water. The mixture is formed from two of more lead sorbents. The lead sorbents exhibit a synergistic effect such that the lead adsorption of the mixture of materials is greater than the theoretical maximum absorption of the individual components of the mixture. Mixtures of lead sorbents that exhibit synergistic lead adsorption are characterized by elemental compositions within specified ranges by weight, as measured by x-ray fluorescence.
