Abstract
The O/C atomic ratio of biomass-derived carbonaceous matter is a universal predictor of porosity and packing density, and enables predictable synthesis of activated carbons that have high methane storage of 222 cm3 (STP) cm−3 at 25 oC and 35 bar.
Highlights
The continuing worldwide growth in the use of gasoline and diesel has led to increasing concerns over the sustainability of oil reserves
The selection of date seed (Phoenix dactylifera) as starting material, which involved extensive assessment of a wide range of biomass sources, was based on date seeds having relatively low elemental oxygen content compared to the elemental carbon content (Table S1, Electronic supplementary information (ESI)†)
In a departure from this current norm, we have shown that the properties of activated carbons can be predictably tailored by choice of the biomass precursor and mode of carbonisation to generate carbons that are highly microporous with high surface area density, high volumetric surface area and high packing density that is optimised for enhanced methane storage at medium pressure (35 bar)
Summary
The continuing worldwide growth in the use of gasoline and diesel has led to increasing concerns over the sustainability of oil reserves. We show that it is possible to use a rational approach to prepare activated carbons with suitable porosity, high packing density and record levels of methane storage capacity
