Abstract
|
Near-critical
fluids possess unique tunability of the physical and transport properties for
performing resource-efficient catalysis characterized by process
intensification, high product selectivity, enhanced safety and facile
separation steps.
Authors review alternative technology concepts for energy-intensive and waste-generating megaton industrial processes that employ gas-expanded liquids or supercritical fluids to demonstrate such process attributes are highlighted. They focus on continuous or flow processes employing either homogeneous or supported ionic liquid phase (SILP) catalysts. Economic and LCA analyses based on plant-scale simulations reveal clear potential for practical viability and lowered environmental impacts of these alternative processes. The emerging biomass and shale gas based chemical industry, where new catalytic technologies are required to make equivalent petrochemical intermediates, may be receptive to adopting such new resource-efficient technologies. |
