This disclosure provides a method of making a high-fixed-carbon material comprising pyrolyzing biomass to generate intermediate solids and a pyrolysis vapor; condensing the pyrolysis vapor to generate pyrolysis liquid; blending the pyrolysis liquid with the intermediate solids, to generate a mixture; and further pyrolyzing the mixture to generate a high-fixed-carbon material. A process can comprise: pyrolyzing a biomass-comprising feedstock in a first pyrolysis reactor to generate a first biogenic reagent and a first pyrolysis vapor; introducing the first pyrolysis vapor to a condensing system to generate a condenser liquid; contacting the first biogenic reagent with the condenser liquid, thereby generating an intermediate material; further pyrolyzing the intermediate material in a second pyrolysis reactor to generate a second biogenic reagent and a second pyrolysis vapor; and recovering the second biogenic reagent as a high-yield biocarbon composition. The process can further comprise pelletizing the intermediate material. Many process and system configurations are disclosed.

A system and process for the recovery of at least one anesthetic from a gas stream including at least two anesthetics. The recovery includes adsorption by exposing the gas stream to an adsorbent. The adsorbent is then regenerated by exposing the adsorbent to a purge gas under conditions which efficiently desorb the at least two anethetics from the adsorbent. The at least two anesthetics (and impurities or reaction products) are condensed from the purge gas and subjected to fractional distillation to provide a recovered anesthetic.

Particulate material comprising rough mesoporous hollow nanoparticles. The rough mesoporous hollow nanoparticles may comprise a mesoporous shell, the external surface of which has projections thereon, the projections having smaller sizes than the particle size. The particulate material may be used to deliver active agents, such as insecticides and pesticides. The active agents can enter into the hollow core of the particles and be protected from degradation by sunlight. The rough surface of the particles retains the particles on plant leaves or animal hair. Methods for forming the particles are also described. Carbon particles and methods for forming carbon particles are also described.

Polystyrene waste, such as Styrofoam® waste, and carbon nanofibers may be used to produce highly hydrophobic compositions or composites that can separate oil and water. Methods for purifying an aqueous solution may include: passing the aqueous solution, including a hydrophobic organic substance, over or through a surface including a polystyrene-CNF composition, thereby producing an aqueous product including less of the hydrophobic organic substance; and optionally, passing the aqueous product over or through the surface at least one more time.

A method for producing a porous copolymer monolith substrate for use in flow through liquid chromatography applications is disclosed. The method comprises forming a reaction composition comprising at least one monoethylenically unsaturated aryl monomer, at least one polyethylenically unsaturated aryl monomer, a RAFT agent, at least one liquid porogen, and a radical initiator. The reaction composition is introduced to a mold having a shape and dimensions suitable for forming a liquid chromatography substrate. The monoethylenically unsaturated aryl monomer, the polyethylenically unsaturated aryl monomer and the RAFT agent are copolymerised in the mold under conditions to form a solid copolymer network that is phase-separated from the reaction composition and/or any liquid components.
