Abstract
A sulfur removal system including a first reactor and a second reactor that are located in series to one another each having an adsorbent that includes cobalt and copper on an activated carbon support, a method of desulfurizing a sulfur-containing hydrocarbon stream via the sulfur removal system, and a method of making the adsorbent. Various embodiments of the sulfur removal system, the desulfurizing method, and the method of making the adsorbent is also provided.
Claims6
A vertically mounted sulfur removal system, comprising:
- a first reactor comprising
- a first vessel having a first internal cavity with a first adsorbent bed that contains a first adsorbent,
- a first inlet, located proximal to a bottom of the first vessel, and
- a first outlet located proximal to a top of the first vessel;
- wherein the first reactor is a fluidized-bed reactor and the first vessel is in the form of a cylinder mounted vertically along the axis of the cylinder;
- and
- a second reactor comprising
- a second vessel having a second inlet, a second outlet, and a second internal cavity with a second adsorbent bed that contains a second adsorbent,
- wherein the second reactor is a fixed-bed reactor and the second vessel is in the form of a cylinder mounted vertically along the axis of the cylinder
- wherein the first and the second adsorbents comprise cobalt and copper on an activated carbon support,
- wherein the first adsorbent bed has a cross-sectional area that is substantially the same as a cross-sectional area of the first vessel, and
- wherein the second inlet is fluidly connected to the first outlet via a connecting line.
