Use for h2s waste gas
An exothermic carbon dioxide process using an Ionic Liquid synthesized from inexpensive, food-grade renewable materials can absorb CO2 effectively. The molar ratio of CO2 and the IL can reach 0.6.
The CO2 can be easily released under vacuum or bubbling gas through the solution, and can be reused. Both chemical and physical absorption exis
An exothermic carbon dioxide process using an Ionic Liquid synthesized from inexpensive, food-grade renewable materials can absorb CO2 effectively. The molar ratio of CO2 and the IL can reach 0.6.
The CO2 can be easily released under vacuum or bubbling gas through the solution, and can be reused. Both chemical and physical absorption exist in the system. The solubility CO2

Low cost high value catalysis
Use for h2s waste gas
The removal of H2S from hot coal gas using a limestone-based sorbent generates a large quantity of calcium sulfide waste (e.g., 67 tons/day from the gasification of 1000 tons/day of 3% S coal) that cannot be landfilled because of potential H2S evolution and sulfide leaching. In the process proposed here, the CaS is dissolved by reaction w
The removal of H2S from hot coal gas using a limestone-based sorbent generates a large quantity of calcium sulfide waste (e.g., 67 tons/day from the gasification of 1000 tons/day of 3% S coal) that cannot be landfilled because of potential H2S evolution and sulfide leaching. In the process proposed here, the CaS is dissolved by reaction with Sulfur to form a polysulfide and this with a carbon carrier used to increase the efficiency of acidic electrolysis of water as an anode depolarizer forming sulfuric acid and calcium sulfate with hydrogen at the cathode.

The high cost and potential toxicity of precious metals make them less desirable for industrial applications. Doyen is developing low cost iron pincer-like catalysis with noble metal activities. Iron catalysis is attractive for organic synthesis because iron is inexpensive, abundant, and non-toxic. To control the activity and stability of
The high cost and potential toxicity of precious metals make them less desirable for industrial applications. Doyen is developing low cost iron pincer-like catalysis with noble metal activities. Iron catalysis is attractive for organic synthesis because iron is inexpensive, abundant, and non-toxic. To control the activity and stability of an iron center, a large number of iron pincer-like complexes have been synthesized using simple synthesis and low cost ligands

New Hydrogen Carriers
Sunshine helps provide drinking water
New Hydrogen Carriers
Liquid organic hydrogen carriers (LOHCs) for the storage of hydrogen is based on the reversible hydrogenation of an unsaturated,
compound. This reaction forms a saturated hydrogen-rich form of the carrier. In the dehydrogenation reaction, the hydrogen-rich form releases the hydrogen for further utilization.
Useful Heat storage

New Hydrogen Carriers
Concrete’s properties can be changed with low cost readily available additives to match a given requirement and serve as an effective thermal storage medium which can be charged and discharged. Very high heat capacity was a surprise for a low cost waste material. Envisioned are driveways, parking lots storing energy
