The effect of alkali impurities on Co-based Fischer–Tropsch (FT) catalysts is important for processing biomass-derived synthesis gas containing inorganic ash impurities. The effects of Na, K, Li, and Ca impurities on γ-Al2O3-supported Co–Re powder catalysts were studied at impurity loadings between 25 and 1,000 ppm. Impurity addition did not have any effect on H2 chemisorption, but the catalyst activity decreased during FT synthesis experiments. The impurities were also found to slightly… 

Microcalorimetric Studies on Co–Re/γ-Al2O3 Catalysts with Na Impurities for Fischer–Tropsch Synthesis

In Fischer–Tropsch synthesis (FTS), sodium impurities originating from biomass feedstock can be introduced into the catalyst as traces via the synthesis gas. The addition of small amounts of Na to a

Fischer–Tropsch conversion of biomass‐derived synthesis gas to liquid fuels

Recent and ongoing research on Fischer–Tropsch catalysts for biomass conversion typically focus on the effects of impurities common in bio‐derived synthesis gas, and also on the effect of different

Fischer–Tropsch Synthesis: Effect of Halides and Potassium Addition on Activity and Selectivity of Cobalt

The effect of halides and potassium addition on cobalt Fischer–Tropsch synthesis (FTS) was studied using 1L CSTR at 493 K, 1.99 MPa and H2/CO of 2.0. The potential catalyst poison was co-fed with

Fischer–Tropsch Synthesis on SiC-Supported Cobalt Catalysts

Seven SiC supports provided by SICAT with different surface areas and pore volumes were impregnated with 12,5 wt% Co. H2-chemisorption, N2-adsorption, temperature programmed reduction and

Removal of sodium compounds from Co/SBA-15 catalysts for Fischer-Tropsch Synthesis

In the present work, the synthesis of Co/SBA-15 catalysts intended for Fischer-Tropsch (FT) synthesis was performed. During the synthesis of catalysts there was contamination of samples with sodium



CO hydrogenation over potassium promoted iron, cobalt, and nickel Catalysts Prepared from Cyanide Complexes

Several potassium promoted catalysts have been prepared by adsorption of K4[Fe(CN)6], K3[Co(CN)6] and K2[Ni(CN)4] on acid-modified γ-alumina. Subsequent H2 treatment with or without previous

Long‐range poisoning of D2 dissociative chemisorption on Pt(111) by coadsorbed K

We report detailed molecular beam studies of the effects of K adsorption on the dissociative chemisorption probabilities S0 for D2 on Pt(111). In contrast to conventional wisdom for many other

Slagging Characteristics during Combustion of Corn Stovers with and without Kaolin and Calcite

Ash-related problems have more than occasionally been observed in biomass-fired boilers and also recently in biopellet burners. These problems can lead to reduced reliability of the combustion syst
