An carbon molecular sieve for adsorbing water molecules in an alcohol solution to separate an alcohol from the water molecules, wherein the total volume of pores with an inlet diameter of 0.33 nm or more as determined by a molecular probe method is not less than 3 times the total volume of pores with an inlet diameter of 0.46 nm or more. This carbon molecular sieve is an alcohol concentration material that is capable of efficiently concentrating alcohol without performing a distillation step and that is easily reusable.

Some variations provide a remediation composition for pesticide and/or heavy-metal remediation of a biomass extract, the remediation composition comprising at least one polysaccharide, at least one metal oxide, and at least one metal salt. Some variations provide a process for producing a biomass extract from a biomass feedstock, comprising: providing a starting biomass feedstock that contains a pesticide or a heavy metal; exposing the starting biomass feedstock to a process solvent, thereby forming a biomass extract dissolved and/or suspended in the process solvent, wherein the pesticide or heavy metal are contained in the biomass extract; providing a separation media containing a polysaccharide, a metal oxide, and a metal salt; and introducing the biomass extract to the separation media, wherein the pesticide or the heavy metal are removed by the separation media, thereby generating a remediated biomass extract. Systems utilizing the remediation composition in fixed or fluidized beds are described.
