N2  - This chapter is the synopsis of the recent investigation on hydrogen-rich syngas generation using ethanol dry reforming approach over rare-earth metal-supported cobalt catalysts. Ce- and La-promoted and unpromoted 10Co/Al2O3 catalysts were synthesized by co-impregnation technique and were characterized using a wide range of methods, namely, Brunauer-Emmett-Teller (BET) surface area, X-ray diffraction (XRD) measurement, temperature-programmed oxidation (TPO), H2 temperature-programmed reduction (H2-TPR), NH3 temperatureprogrammed desorption (NH3-TPD) and Raman spectroscopy measurements. The influence of operating conditions including varying CO2:C2H5OH ratios from 2.5:1 to 1:2.5 and reaction temperature range of 923-973 K was also investigated in this chapter. The addition of both CeO2 and La2O3 promoters facilitated the H2 reduction, enhanced the basic property of catalysts and improved active metal dispersion. Regardless of reaction temperature and reactant composition, La-promoted catalyst exhibited the highest C2H5OH and CO2 conversions followed by Ce-promoted and unpromoted catalysts. The increment of CO2 partial pressure from 20 to 50 kPa enhanced C2H5OH and CO2 conversions by up to 20.0 and 27.4, respectively. However, reactant conversions significantly declined with growing C2H5OH partial pressure from 20 to 50 kPa. La and Ce addition hindered carbon deposition on catalyst surface during ethanol dry reforming reaction, and the amount of carbon deposition declined from 51.49 to 30.06 with the addition of La. © Springer Nature Singapore Pte Ltd. 2018.
