Optimization of hydrogen production via coupling of the Fischer–Tropsch synthesis reaction and dehydrogenation of cyclohexane in GTL technology

Preparation and characterization of activated aluminum powder by magnetic grinding method for hydrogen generation

“…The results demonstrated that the grinding time had remarkable effects on the hydrolysis reactivity of aluminum powder and the hydrolysis rate increased with the increase of the contact surface area of aluminum in alkali solution. It is consistent with previous reports that the aluminum powder needs to be ground first to break particles into smaller ones in order to increase its specific surface area and, consequently, the chemical activity [25]. Therefore, appropriate grinding time could help speed up the hydrolysis rate of aluminum powder.…”

Catalytic Combustion for Supplying Energy for Endothermic Reaction

“…A typical single membrane-assisted configuration for hydrogen production consists of a concentric three tube reactor: in the inner tube the exothermic reaction occurs, the intermediate channel is employed for the endothermic reaction while the external channel is used for hydrogen recovery since the wall separating the intermediate and the external channel functions as an hydrogen selective membrane [18,[55][56][57][61][62][63][64][65][66][67]. An alternative to this kind of arrangement considers the exothermic and the endothermic reactions in external and intermediate chambers, respectively, and hydrogen recovery from the inner tube [58].…”

“…The DE optimization strategy was successfully adopted also in membrane-assisted recuperative coupling reactors [56,63,66,[68][69][70][71]. In particular, Rahimpour et al proposed this technique to optimize the performance of a double membrane reactor: an water selective membrane was inserted to remove water from the exothermic side so to increase the productivity of gasoline synthesized from syngas and a Pd-Ag membrane was added to the endothermic side to separate H 2 produced from dehydrogenation of decalin [17,68,70,71].…”

Progress in Reactors for High-Temperature Fischer–Tropsch Process: Determination Place of Intensifier Reactor Perspective

“…First the features and performances of earlier reactors are investigated, and their weaknesses for HTFT synthesis are discussed. Then the same study is done for product intensifier reactors which are recent innovative configurations [29][30][31][32][33]. Ultimately, results show that product intensifier reactor can be feasible and beneficial for achieving the renewable energy.…”
