Abstract
Hydrogen is supplied first to a last hydrogenation zone, and gases recovered from the last hydrogenation zone are passed to the first hydrogenation zone of a continuous multi-zone liquid phase process for hydrogenating an organic compound to a corresponding hydrogenation product. The organic compound, with a suitable diluent or recycle hydrogenation product, flows successively through the zones beginning with the first and ending with the last hydrogenation zone to undergo hydrogenation with the hydrogenation product being recovered from the last hydrogenation zone.
