Steam Reforming of Methane on the Ni-Re Catalysts

Borowiecki T., Denis A., Pańczyk M., Gac W., Stołecki K.

Polish Journal of Chemistry

2008

Vol. 82, nr 9

1733-1742

The influence of rhenium on the properties of a commercial nickel catalyst in the steam reforming of methane was presented. The addition of Re up to 4 wt. % causes the in crease of the amount of chemisorbed hydrogen, dispersion of active phase, catalyst activity as well as its resistance to coking. The investigations show a good agreement be tween the resistance to coking obtained by the temperature-programmed reaction (TPReaction) and by the traditional thermogravimetric method. The obtained results are very interesting particularly concerning the increase in both activity and resistance to coking.

Promoted nickel steam reforming catalysts: influence of thermal treatment on the activity and resistance to coking

Borowiecki T., Gołębiowski A., Stołecki K., Stasińska B.

Polish Journal of Chemical Technology

1999

Vol. 1, nr 1

2-6

An introduction of small amounts of promoters (Mo, W, Ba, K) into the nickel catalysts of the steam reforming of hydrocarbons reduces the detrimental effect of carbon deposit formation. Pressurized thermal treatment of the catalysts in a H2O:H2 mixture indicates that the promoting effect of the examined additions exhibits considerable stability. Ni-Mo or Ni-W catalysts can be used in the industrial processes (e.g. prereforming process).
