## Abstract The volumetric gasβliquid mass transfer coefficient, __k____~L~__Ξ±, for oxygen was studied by using the dynamic method in slurry bubble column reactors with high temperature and high pressure. The effects of temperature, pressure, superficial gas velocity and solids concentration on the
Corrosion of alloy 625 (NiCr22Mo9Nb; 2.4856) pressure tubes was investigated in aqueous solutions of phosphoric acid (0.05 Β± 1.0 mol/kg) and oxygen (0.48 mol/kg) at temperatures up to 500 8C and pressures of 24 MPa. Reaction times were up to 185 h. At acid concentrations below 0.1 mol/kg, no corros
