Methanol and methyl fuel catalysts. Final technical report, September 1978-August 1980
The Cu/ZnO methanol synthesis catalysts were investigated for (1) the role of additives such as alumina, ceria, and lanthana, (2) the effect of carbon dioxide in the H/sub 2//CO synthesis gas, (3) the chemisorption of hydrogen and carbon monoxide on the catalysts, and (4) the chemical poisoning of the catalysts by sulfur- and chlorine-containing compounds. Maximum activity and selectivity were obtained with a binary catalyst having a composition of Cu/ZnO = 30/70 metal atomic percent and with a synthesis gas of H/sub 2//CO/CO/sub 2/ = 70/28/2 volume percent in the absence of strongly reducing or strongly oxidizing chemical poisons. Both the binary and the ternary catalysts were fully characterized by scanning transmission electron microscopy (STEM), X-ray diffraction, electron spectroscopy, diffuse reflectance spectroscopy, and surface area-pore distribution measurements. Structural and morphologic information is presented in this report in detail for very active Cu/ZnO/Al/sub 2/O/sub 3/ catalysts prepared from acetates and for other catalysts in which the third component caused a loss of activity.
