Chloride Poisoning of Iron–Copper Fischer–Tropsch Catalysts.

Direct catalytic conversion of synthesis gas to lower olefins

“…It is well-known that the presence of chlorine and other halogens deactivates a FT catalyst (Fischer and Tropsch, 1932;Hofer et al, 1946Hofer et al, , 1951. The patent information on the influence of organic halogen compounds with Febased catalysts shows that the selectivity to olefins in the C2-C4 fraction was considerably increased, while the paraffin content was reduced in comparison with an untreated catalyst.…”

Ultrathin N-rich boron nitride nanosheets supported iron catalyst for Fischer–Tropsch synthesis

“…The value of FeBN2 was about triple of that of FeBNCl, which was in agreement with the fact that the Cl contaminated catalyst showed a suppress the hydrogenation activity. 42 The Fe/BNNS showed different performance in FTS as a function of Fe loadings, as shown in Fig. 6.…”

Identification of Porphyrins by the X-Ray Powder Method

“…The applicability of x-ray powder patterns for distinguishing between closely related, complicated organic molecules has been explored systematically for several classes of compounds with positive results-e.g., steroids (3,26,27), fatty acid derivatives (16,23,24), and aromatic hydrocarbons (17). With fatty acids difficulties are encountered because of ready transformation into different modifications (28).…”
