Abstract: In a process for the production of fatty alcohol(s) a fatty acid or fatty acid mixture is subjected to esterification with a lower alkanol to form a stream comprising the corresponding lower alkyl ester or esters. The stream is vaporised and subjected to hydrogenation to form a stream comprising fatty alcohol(s) and an amount of unconverted lower alkyl ester(s). This stream is subjected to transesterification in a wax ester reactor in the presence of a solid transesterification catalyst. Fatty alcohol(s) and wax ester(s) are then separated by distillation to yield a fatty alcohol(s) product and a stream comprising wax ester(s). The stream of wax ester(s) is passed to a second hydrogenation zone to effect hydrogenation in the liquid phase to revert the wax ester(s) to fatty alcohol(s), which are returned to the distillation separation step.

Abstract: A reactor system, plant and a process for the production of methanol from synthesis gas is described in which the reactor system comprises: (a) a first reactor adapted to be maintained under methanol synthesis conditions having inlet means for supply of synthesis gas and outlet means for recovery of a first methanol-containing stream, said first reactor being charged with a first volume of a methanol synthesis catalyst through which the synthesis gas flows and on which in use, partial conversion of the synthesis gas to a product gas mixture comprising methanol and un-reacted synthesis gas will occur adiabatically; and (b) a second reactor adapted to be maintained under methanol synthesis conditions having inlet means for supply of the gaseous first methanol-containing stream, outlet means for recovery of a second methanol-containing stream and cooling means, said second reactor being charged with a second volume of a methanol synthesis catalyst through which the gaseous first methanol-containing stream flows and on which, in use, further conversion of the synthesis gas to a product gas mixture comprising methanol will occur.
