In this work, single-stage and two-stage tubular solid oxide fuel cell (SOFC)/gas turbine hybrid cycles are comparatively examined from the energy and exergy viewpoints. For this purpose, mass, energy and exergy balances are applied to all components of the cycles. The behavior of tubular solid oxide fuel cell modeled in this study is validated with the experimental test data of tubular SOFC de...

A two-stage desulfurization process including an abiotic filtration using cellular concrete waste (first stage) and anoxic biotrickling filter filling with inoculated expanded schist material (second was investigated to remove H2S in mimic biogas limited O2 amount (ranged from 0.5 0.8%). The able satisfactorily for all experimental conditions (RE > 97%; concentration = 1500 mg m−3; total Emp...
