摘要： 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.

摘要： The invention relates to: a process for the desulphurization of feed streams comprising: supplying a hot process stream to a lead catalyst bed (8) comprising a first sulphur-removing catalyst and a second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the first sulphur-removing catalyst and said second sulphur-removing catalyst does not effectively remove sulphur from the stream at the operating temperature of the lead catalyst bed for the duration of the bed's life; collecting a hot partially sulphur-depleted stream from the lead catalyst bed and cooling said stream; passing said cooled stream through a lag catalyst bed (11) comprising the first sulphur-removing catalyst and the second sulphur-removing catalyst under conditions whereby sulphur is removed from the process stream by the second sulphur-removing catalyst and said first sulphur-removing catalyst removes sulphur less efficiently from the stream at the operating temperature of the lag catalyst bed; and recovering said sulphur-depleted stream from the second catalyst bed. In addition it relates to, apparatus for the desulphurization of feed streams which comprises: a lead catalyst bed (8) comprising a first sulphur-removing catalyst and a second sulphur-removing catalyst capable of operating under conditions whereby sulphur is removed from the process stream by the first sulphur-removing catalyst and said second sulphur-removing catalyst does not effectively remove sulphur from the stream at the operating temperature of the lead catalyst bed (8) throughout the lead bed's operating life; means (9) for collecting a hot partially sulphur-depleted stream from the lead catalyst bed (8) and cooling said stream; a lag catalyst bed (11) comprising the first sulphur-removing catalyst and the second sulphur-removing catalyst capable of operating under conditions whereby sulphur is removed from the process stream by the second sulphur-removing catalyst and said first sulphur-removing catalyst does not efficiently remove sulphur from the stream at the operating temperature of the lag catalyst bed(11).

摘要： In a process for the production of substitute natural gas, a feed gas is provided to a first and/or second and/or subsequent bulk methanator. The feed gas is subjected to methanation in the presence of a suitable catalyst. An at least partially reacted stream from the first bulk methanator is removed and supplied to the second and/or subsequent bulk methanator where it is subjected to further methanation. A product stream from the final bulk methanator is passed to a trim methanator train where it is subjected to further methanation. A recycle stream is removed downstream of the first, second or subsequent bulk methanator, and, in any order, passed through a compressor, subjected to cooling and then supplied to a trim and/or recycle methanator for further methanation before being recycled to the first and/or second and/or subsequent methanator.
