    Abstract: 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 NG 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 NG, rinsing the column and the adsorbent bed by feeding NG until 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.

    Abstract: The present invention provides a process for preparing ball-type desulfurizer with high sulfur capacity, comprising the following steps: placing initial balls in a rolling equipment; wetting the surface of the initial balls with an aqueous solution of an organic binder; then alternately adding non-crystalline iron oxide hydroxide and the aqueous solution of the organic binder to gradually form small balls of non-crystalline iron oxide hydroxide with high sulfur capacity and different diameters; and adjusting the shape of the small balls and then roasting or naturally drying the small balls. In the desulfurizer prepared by this method, the initial balls constitutes 0.98 wt %-9.03 wt % of the desulfurizer, the non-crystalline iron oxide hydroxide constitutes 90.29 wt %-98.62 wt % of the desulfurizer, and the organic binder constitutes 0.58 wt %-0.89 wt % of the desulfurizer. The present invention solves the problems that the desulfurizer with high sulfur capacity in the prior art has a high binder content and poor water resistance and diffusion performance, and provides a process for preparing a desulfurizer with high sulfur capacity, wherein a desulfurizer with high sulfur capacity and low binder content, good water resistance, good diffusion performance can be prepared.
