Abstract Gas to liquid (GTL) process involves heterogeneous catalytic chemical reactions that convert synthesis gas to hydrocarbons and water vapor. A three phase reactor, called Low temperature Fischer-Tropsch (LTFT) is commonly applied for GTL process. In this reactor the gaseous phase includes the synthesis gas, light hydrocarbons and water vapor, the liquid phase is a mixture of the h...

A conceptual pore level model (Chem. Eng. Sci. 57 (2002) 3401) of spreading of liquid over internally wet porous particles is applied to explain reported rector level enhancement in wetting of trickle bed reactor (Ind. Eng. Chem. Res. 36 (1997) 5133). It is con6rmed that a symbiotic relationship exists between internal and external wetting of porous particles whereby each enhances the other. Fu...

Trickle bed reactors are governed by equations of flow in porous media such as Darcy’s law and the conservation of mass. Our numerical method for solving these equations is based on a total-velocity splitting, sequential formulation which leads to an implicit pressure equation and a semi-implicit mass conservation equation. We use high-resolution finite-difference methods to discretize these eq...

Catalytic wet air oxidation of an aqueous phenol solution was carried out in a trickle bed reactor at mild conditions of temperature (120–160◦C) and oxygen partial pressure (0.6–1.2 MPa). Tests were performed at space times up to 1 h. A commercially available copper oxide supported over g-alumina was used as catalyst. The results show that the phenol conversion, the chemical oxygen demand (COD)...

Abstract Power-to-methane technology is a promising solution to facilitate the use of excess variable renewable energy for biomethane production. In this approach, hydrogen produced via electrolysis used upgrade raw biogas, which can be subsequently as fuel or stored in gas grid. Ex-situ biomethanation an emerging that could potentially replace conventional energy-intensive biogas upgrading met...
