Abstract
Addition of Gd to CO/SiO2 Fischer-Tropsch synthesis catalysts (1) increases reducibility to Co metal, (2) decreases CH4 selectivity, (3) increases act ivity for CO hydrogenation based on the mass of Co, and (4) causes carbon d eposition at lower temperatures when compared to the unpromoted catalyst. T he intrinsic activity, based on H-2 chemisorption surface area, is the same for both unpromoted and promoted catalysts.
