Oxygen concentration and separation is an essential factor for air recycling in a CELSS. Furthermore, if the value of the plant assimilatory quotient is not coincident with that of the animal respiratory quotient, the recovery of O2 from the concentrated CO2 through chemical methods will become necessary to balance the gas contents in a CELSS. Therefore, oxygen concentration and separation equi...

Abstract The present work deals with the chemical recycling of waste polypropylene via thermocatalytic pyrolysis over HZSM‐5 zeolite catalysts. main aim was to systematically investigate influence reactor configuration, acidity, wastes, obtained from different sources, as well catalyst regeneration on product distribution. It demonstrated that configuration and acid site density catalysts stron...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...
