- Abstract
Samples of barium-promoted carbon-supported cobalt catalysts for ammonia synthesis were prepared; the cobalt content was constant (27.4 wt %) and the amount of barium introduced differed within the range of 0-0.88 mmol gC+Co−1. Turbostratic carbon was used as the support. Several techniques, including X-ray powder diffraction, TEM, Thermogravimetric analysis-mass spectrometry (methanation studies) and H2 temperature-programmed desorption were used to examine the properties of the carbon support or catalytic materials. The reaction rate measurements were performed under the following conditions: T=400 °C, p=9.0 MPa, x
