Abstract

When Ru is supported on basic materials, the observed rates of NH3 synthesis were

higher [1,2]. On the other hand, an intensified NH3 synthesis process using an acidic

absorbent -such as MgCl2- in the reactor, maintained a low partial pressure of

ammonia in the gas phase, and the reaction equilibrium shifted to right [3]. Along

these lines, the effect of surface acidity of the hydroxyapatite (HAp), zeolite-Y and

carbon (Vulcan XC72R) supports on the NH3 synthesis rate over Ru is reported in

this study.
