Propylene glycol is discharged to the surface and underground waters and vicinity soils via industrial wastewater effluents, posing many health and environmental risks. The main goal of this study was to remove propylene glycol from synthetic wastewater in a fixed bed activated sludge reactor. To observe the effects of organic loading on bioreactor performance, the organic loading was increased...

To overcome the weak point of gas type heating (failure in uniformly and persistently), liquid molten salt as a concentration solar energy was considered heat source for dry reforming. This high-temperature flowing through center tubular reactor supplies necessary heat. The dependence on number hydrogen production investigated under assumption fixed volume catalyst bed. By changing these number...

The objective of this work is simulating municipal solid waste gasification in fixed bed reactor. A comprehensive process model developed to simulate (MSW) reactor using an Aspen Plus simulation .To predict and analyze the pyrolysis updraft more veritably appropriately, numerical modeling based on Gibbs energy minimization was executed plus software v(9). Rstoic a block that can be used with un...

Abstract The present study aims at development of a mathematical model for the fixed-bed column adsorption that relates reactor parameters with breakthrough curve. Effects operating like bed height, flow rate, initial adsorbate concentration on were investigated by using various curves. arbitrary constants developed found to be dependent kinetics. proposed showed incredible results (Breakthroug...
