Technical and economic feasibility of the Isopropanol-Acetone-Hydrogen chemical heat pump based on a lab-scale prototype

Influence of reduction temperature on Pt–ZrO2 interfaces for the gas-phase hydrogenation of acetone to isopropanol

“…1 The selective hydrogenation of aldehydes or ketones to corresponding alcohols has attracted increasing attention due to its wide applications in chemical manufacturing, heat upgrading, energy storage, and health protection. 2,3 In particular, acetone hydrogenation plays an important role in renewable energy fields such as isopropanol (IPA)-acetone-hydrogen chemical heat pumps, H 2 storage schemes and direct IPA fuel cells (giving higher energy production and better stability than those of methanol or ethanol), which requires higher IPA selectivity and acetone conversion than presently available. 4,5 Conventionally, IPA is a valuable bulk commodity (massively produced by oil-derived propene hydration 6 ) extensively used in paint, medicine, and pesticide industries with growing demands, suffering from the deficiency of oil and intensive energy input.…”

Ni-Foam-Structured Ni–Al2O3 Ensemble as an Efficient Catalyst for Gas-Phase Acetone Hydrogenation to Isopropanol

“…Undoubtedly, acetone hydrogenation is a sustainable and economical route to transform the inventory acetone to value-added IPA. Moreover, this process also attracts interest in an IPA–acetone–hydrogen chemical heat pump and hydrogen storage for fuel cells. − …”
