A key challenge for future clean power or hydrogen projects via gasification is the need to reduce the overall cost while achieving significant levels of CO 2 capture. The current state of the art technology for capturing CO 2 from sour syngas uses a physical solvent absorption process (acid gas removal–AGR) such as Selexol™ or Rectisol ® to selectively separate H 2 ...
Sorption-enhanced water-gas-shift (SEWGS) is a pre-combustion decarbonisation technology combining adsorption of CO 2 with the water-gas-shift reaction. This process maximises the production of hydrogen from syngas whilst simultaneously capturing and separating CO 2 .Simulations have been completed to evaluate the use of SEWGS for power generation from natural gas with carbon capture...
A new variant of the zero length column method (tracer ZLC) has been developed and used to study the self-diffusion of propane and propylene in 5A and 13X zeolite crystals at 358 K. Diffusivities of propane and propylene in both zeolites are similar; the diffusivities in 13X are about an order of magnitude greater than for 5A. For propane-5A the tracer diffusivities are consistent with the corrected...
