Catalytic performance of zirconium-modified Co/Al2O3 for Fischer–Tropsch synthesis

Promotion Effects in Co‐Based Fischer—Tropsch Catalysis

“…Another recent study by Xiong et al has reported on the F-T catalytic performances of Zr-modified Co/Al 2 O 3 catalysts. 257 The CoAl 2 O 4 spinel phase was detected in the prepared catalysts and its content decreased with increasing Zr loading. Thus, Zr appeared to inhibit the Co-support formation in the catalysts.…”

“…-The following chemical elements have been investigated as promoters in Co-based F-T catalysis: B, Mg, K, Ti, V, Cr, Mn, Ni, Cu, Zr, Nb, Mo, Ru, Rh, Pd, La, Re, Ir, Pt, Ce, Gd and Th. [247][248][249][250][251][252][253][254][255][256][257][258][259][260][261] Taking the above described classification scheme, we have made an attempt to identify for every reported promoter element its beneficial effect for Co F-T catalysis. The result of this effort is summarized in Table 3 3.2.1.1 Ruthenium.…”

Zeolite Catalysis

“…Based on early literature reports revealing the improved selectivity of C 5+ hydrocarbons due to addition of Zr as promotor to Co-based Fischer-Tropsch catalysts [278][279][280], Huang et al…”

Zeolite Membranes in Catalysis—From Separate Units to Particle Coatings

“…Based on early literature reports revealing the improved selectivity of C5+ hydrocarbons due to addition of Zr as promotor to Co-based Fischer-Tropsch catalysts [278][279][280], Huang et al [258] prepared H-ZSM-5 enwrapped CoZr catalyst particles and evaluated their activity for the direct synthesis of gasoline-ranged i-paraffins. The authors employed aluminum isopropoxide as Al source during membrane synthesis and confirmed its beneficial impact with respect to the minimized coke deposition.…”
