Catalytic components and reactor configuration for increased selectivity and productivity. Increasing global CO2 levels have led to a thrust in research on Carbon Capture and Storage (CCS) and Carbon Capture and Utilization (CCU). In terms of volume, the contribution of CCU will be significantly less compared to CCS for avoiding CO2 emissions and achieving the…

In April 1993, Micromeritics introduced a software package called DFT V1.00. This program was the first commercial offering of a practical method to routinely analyze experimental adsorption isotherms using methods based on modern theoretical physical chemistry. It was the culmination of an investigation by James P. Olivier and William B. Conklin into a method by…

A Brief History of Density Functional Theory Applied to Extracting Information from the Physical Adsorption Isotherm During the 1980s, considerable progress was made toward a theoretical understanding of fluid behavior in non-homogeneous systems. Particular interest was focused on phase changes in fluids constrained by the presence of walls, capillaries, and slits. A paper that…
