A se.ie. of tungste. p.omote. alumina sup.orte. nicke. catalysts has be.n p.e.0}re. for the.carbon dioxide.re.orming of me.hane.to synthe.is gas. The.catalysts have.be.n characte.ize. by me.ns of XRD, Te., and Lase. Raman sp.ctroscop.. It is shown that the.addition of tungste. to the.nicke. catalyst can stabilize.the.catalyst and incre.se.the.re.istance.to carbon de.0}sition. Adding a suitable.amount of tungste. can also incre.se.the.catalyst activity to be.close.to that of sup.orte. noble.me.al catalysts. The.carburisation of the.tungste. modifie. nicke. catalyst de.re.se. the.catalyst activity at lowe. re.ction te.p.rature.(e.fe.t on the.catalyst p.rformance.at highe. re.ction te.p.rature.. The.alumina sup.orte. nicke. catalyst modifie. by 0.67%(mass fraction) WO_3 has the.e.uivale.t e.uilibrium constant of the.dry re.orming re.ction to that of alumina sup.orte. 5%(mass fraction) Ru at 873 K, and also has a lowe. activation e.e.gy for dry re.orming than the.latte..
