Conversion of methanol to hydrocarbons on cobalt and lanthanum catalysts

γ-Alumina supported cobalt (4 wt%) and cobalt-lanthanum with different lanthanum content (2,4 and 6 wt%) have been used as catalysts for methanol conversion. The catalysts were physically characterized using: X-ray diffraction technique, hydrogen temperature programmed reduction (TPR) and BET surface area measurements. The results established the formation of Co 3O4 and LaCoO 3 oxide phases. The catalytic behavior of the prepared catalysts was investigated under atmospheric pressure in a pulse micro-reactor operating between 200 to 300°C and a nitrogen carrier gas flow 50 ml/min. The hydrocarbon-converted products discriminate the role of the different formed oxide phases of cobalt and lanthanum on the catalytic behavior of methanol conversion.
