Embodiments provide a methane microporous carbon adsorbent including a thermally-treated CVD carbon having a shape in the form of a negative replica of a crystalline zeolite has a BET specific surface area, a micropore volume, a micropore to mesopore volume ratio, a stored methane value and a methane delivered value and a sequential carbon synthesis method for forming the methane microporous carbon adsorbent. Introducing an organic precursor gas for a chemical vapor deposition (CVD) period to a crystalline zeolite that is maintained at a CVD temperature forms the carbon-zeolite composite. Introducing a non-reactive gas for a thermal treatment period to the carbon-zeolite composite maintained at a thermal treatment temperature forms the thermally-treated carbon-zeolite composite. Introducing an aqueous strong mineral acid mixture to the thermally-treated carbon-zeolite composite forms the methane microporous carbon adsorbent. The crystalline zeolite includes tri-ethanolamine (TEA) and has a shape that is orthogonal with a mid-edge length in a range of 8 &#x3bc;m to 20 &#x3bc;m.
