    (54) Improved process for the production of edible oils


    (57) The present invention relates to an improvement to a hydrogenation process for the production of moderate and high selectivity edible oils which results in a reduction in the required catalyst and in hydrogen consumption. The improvement comprises the use of high purity hydrogen (i.e. from a liquid hydrogen source); the use of a predetermined catalyst concentration, reaction starting temperature, and maximum temperature which is determined by product selectivity; and the use of reactor venting in relationship to the concentration of moisture in the feedstock and the gas mixing mechanism in the reactor.
