摘要： The invention provides a for the removal of oxygenate from an olefin rich gas stream, the process comprising the steps of: (a) reacting an oxygenate feedstock, comprising oxygenate, in an oxygenate reaction zone in the presence of a catalyst comprising a molecular sieve, at a temperature in the range of from 350 to 1000°C, to produce a reaction effluent stream, comprising at least oxygenate, olefin, water and acidic by-products; (b) cooling the reaction effluent stream and contacting it with a first aqueous stream in a quench zone to produce an aqueous stream and an olefin rich gas stream; (c) compressing the olefin rich gas stream in one or more compressors in series to produce a compressed gas stream, (d) cooling the compressed gas stream and separating condensed material from said gas stream after each of the one or more compressors, wherein after at least one of the one or more compressors in step (c), step (d) is carried out by contacting the compressed gas stream directly with a second aqueous stream and separating the resultant material into an oxygenates depleted gas stream and an aqueous wash stream.

摘要： This invention concerns a method for producing a gas comprising at least 80 vol% carbon monoxide from a Fischer-Tropsch off-gas. The method comprises the following steps: (1) feeding Fischer-Tropsch off-gas through a column comprising an adsorbent bed at high pressure and discharging effluent; (2) reducing the pressure in the column and the bed slightly; (3) rinsing the column and the adsorbent bed with methane or carbon dioxide; (4) rinsing the column and the adsorbent bed with carbon dioxide; (5) reducing the pressure of the column and adsorbent bed to a low pressure; (6) rinsing the column and adsorbent bed with a mixture of hydrogen and nitrogen; (7) pressurizing the column and adsorbent bed to a high pressure again using a mixture of hydrogen and nitrogen. The carbon monoxide rich product stream obtained in step (3) can be sent as feed to a Fischer-Tropsch reaction. Step (4) produces a methane stream comprising at least 80 vol% methane. In a preferred embodiment a gas comprising at least 80 vol% hydrogen is produced as well. [Figure 1]

摘要： This invention concerns a method for recovering carbon monoxide and carbon dioxide from Fischer-Tropsch off-gas by feeding Fischer-Tropsch off-gas through a column comprising an adsorbent bed, and discharging effluent, optionally rinsing the column and the adsorbent bed by feeding carbon dioxide and discharging effluent until at least 60% of the carbon monoxide that was present in the bed is discharged, pressurizing the column and adsorbent bed with carbon dioxide, rinsing the column and the adsorbent bed by feeding carbon dioxide, until at least 60% of the methane and optionally an amount equal to at least 50% of the carbon dioxide present at the commencement of this rinsing step is discharged, rinsing the column and adsorbent bed by feeding a mixture of hydrogen and nitrogen, pressurizing the column and adsorbent bed by feeding a mixture of hydrogen and nitrogen. With this method a feed comprising at least 50 vol% carbon monoxide can be produced. Furthermore, methane and carbon dioxide at a high pressure can be recovered from the Fischer-Tropsch gas. This can be fed to a gasifier or a reformer. In a preferred embodiment a gas comprising at least 80 vol% hydrogen is produced as well.
