TPR and TPD studies were carried out on alumina supported Ru:Mn system. From the experimental data it could be conluded that the addition of the Mn produces new sites which are responsible for the production of high molecular weight hydrocarbons. The data has been discussed in terms of the modification of surface electronically and geometrically by the addition Mn to the Ru/Al2O3 system.
