Model-Based Quality, Exergy, and Economic Analysis of Fluidized Bed Membrane Reactors [PDF]

Membranes, 2021
In petroleum refineries, naphtha reforming units produce reformate streams and as a by-product, hydrogen (H2). Naphtha reforming units traditionally deployed are designed as packed bed reactors (PBR). However, they are restrained by a high-pressure drop,
