Direct Synthesis of 2-Methyl-1-Propanol/Methanol Fuels and Feedstocks: Final Technical Report, September 15, 1984-January 14, 1988 (Revision 1)

摘要

The preparation of alkali (particularly Cs) promoted Cu/ZnO and Cu/ZnO/M2 O s (where M = Al, Cr, or Ga) catalysts has been optimized and the reaction conditions for the production of methanol and of C2 -C4 alcohols, especially the branched 2-methyl-1-propanol product, have been optimized with respect to yields and selectivities. A five parameter kinetic reaction network has been developed for the synthesis of oxygenates from synthesis gas over the Cs promoted catalysts. The model successfully describes the 16-compound alcohol and ester product distribution obtained for a range of operating conditions and has been used for predicting the conditions required to attain specified 2-methyl-1-propanol/methanol selectivities and yields. The temperature dependence and apparent activation energy were determined for each of the model parameters, which allows the prediction of the product composition in a wide range of process conditions. Additional studies, in which (13)C labeled alcohols have been added to the feed gas, show that the distribution of the (13)C in the product alcohols and esters is consistent with the proposed reaction paths of the kinetic network. 77 refs., 83 figs., 48 tabs.
