The conversion of alcohols, ethers, and carbonyl compounds using zeolite [beta], zeolite ZSM-5, and zeolite Y are compared and contrasted. The proton form of zeolite [beta] is found to be as active as H-ZSM-5 for this reaction, whereas zeolite Y is much less active. Zeolite [beta] gives isobutane as the major product from methanol conversion under all reaction conditions tested, together with significant selectivities to C[sub 2] and C[sub 3] hydrocarbons. The conversions of ethanol and propanol over zeolite [beta] lead to the almost exclusive formation of the corresponding alkene via water elimination. This is in contrast to ZSM-5, and hence zeolite [beta] does not exhibit the rapid secondary conversion reactions typified by ZSM-5 for alcohol conversion reactions. The high selectivity to iso-C[sub 4] hydrocarbons is also found for zeolite [beta] for the conversion of acetone and acetic acid. The results are discussed in terms of the possible mechanisms for the formation of iso-C[sub 4] hydrocarbons in high selectivity for zeolite [beta]. 28 refs., 7 figs., 5 tabs.
