Abstract: Methods for removing acid gases from feed gas: - A method for removing acid gas from feed gas, comprising alternating input of feed gas between beds of adsorbent particles that comprise zeolite SSZ-98 or SSZ-105; wherein gas contacts one of the beds during an adsorption and tail gas is vented from another bed by desorption; wherein a product gas containing no greater than about 2 mol% carbon dioxide is produced, and methane and ethane are recovered. - A process for removing acid gas from feed gas, comprising adjusting selectivity of an adsorbent by changing a substitution of ERI phase with LEV phase in an intergrown molecular sieve. - A process for removing acid gas from a feed gas, comprising: contacting a feed gas with adsorbent comprising a molecular sieve having a defined intergrowth of an ERI phase and a LEV phase.
