摘要

Abstract

The nature of support and type of active metal affect catalytic performance. In this work

the effect of using La

as promoter and support for Ni/γ-Al

catalysts in dry reforming of methane was investigated. The reforming reactions were carried out at atmospheric pressure in the temperature range of 500-700℃. The activity and stability of the catalyst

carbon formation

and syngas (H

/CO) ratio were determined. Various techniques were applied for characterization of both fresh and used catalysts. Addition of La

to the catalyst matrix improved the dispersion of Ni and adsorption of CO

thus its activity and stability enhanced.
