The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 16606-55-6, Name is (R)-4-Methyl-1,3-dioxolan-2-one, SMILES is O=C1OC[C@@H](C)O1, in an article , author is Li, Congcong, once mentioned of 16606-55-6, Product Details of 16606-55-6.
Nitrogen-Modified Activated Carbon Supported Cu(II)Cu(I)/NAC Catalysts for Gas-Solid Acetylene Dimerization
Improving dispersibility and stability of Cu(II)Cu(I)/activated carbon (AC) is a crucial aspect for enhancing its catalytic performance in the process of gas-solid acetylene dimerization. The Cu(II)Cu(I)/NAC-500 catalyst using nitrogen-modified AC (NAC) as a support, delivered excellent catalytic performance and stability vs undoped Cu(II)Cu(I)/AC at 100 degrees C and 120 h(-1) of C2H2 gas hourly space velocity. Under the optimal conditions, the Cu(II)Cu(I)/NAC-500 catalyst exhibited a stable catalytic performance during a 10 h test with 65% C2H2 conversion; and the selectivity to monovinylacetylene (MVA) reached 86%. The existence of nitrogen species can increase the interaction between copper and the support, and increase dispersion of the copper species on the support, which were benefit for the catalytic performance.
