    摘要： Process for the production of concentrated sulphuric acid and oleum from feed gases with up to 70 % SO 2 + SO 3 (SO x ) and a content of H 2 O corresponding to H 2 O/SO 3 molar ratios up to 1.6, particularly in the range of 0.5 to 1.6 upstream an intermediate sulphuric acid condenser comprising an air recycling loop with water addition. The process of the invention minimizes power consumption of the sulphuric acid plant by reducing the consumption of cooling water and obtaining maximum possible recovery of the heat liberated in the process for production of high pressure steam for power production. Up to 99.95% of the SO x in the feed gas can be recovered as typically 98.5-99.5 wt% concentrated sulphuric acid and/or oleum with up to 25 wt% SO 3 .

    摘要： Process for the production of acetic acid comprising the steps of:
    (a) passing a feed stream containing ethanol and water together with a predetermined feed rate of an oxygen containing atmosphere in presence of one or more catalysts being active in simultaneous non-oxidative and oxidative conversion of ethanol to a product stream with acetic acid;
    (b) recovering from the product stream a stream of acetic acid;
    (c) optionally recovering reactive derivatives of acetic acid and recycling these to step (a).
    A reactor for use in the process comprises a first and at least a second fixed catalyst bed with a catalyst being active in simultaneous non-oxidative and oxidative conversion of ethanol to acetic acid;
    inlet means for a fed stream comprising ethanol, water and a first portion of an oxygen containing atmosphere to the first catalyst bed;
    between the first and at least second catalyst bed inlet means for a second portion of the oxygen containing atmosphere and means for distributing and mixing the second portion of the oxygen containing atmosphere into an effluent of partly converted feed stream from the first catalyst bed; and
    means for passing the partly converted feed stream and admixed with the oxygen containing atmosphere into the at least second catalyst bed.
