Abstract:
1. An apparatus for removing mercury from the products of fuel conversion comprising: means for separating a starter batch of carbonaceous sorbent into a contact batch of carbonaceous sorbent and a retained batch of carbonaceous sorbent, the contact batch of carbonaceous sorbent having a particle size distribution of carbonaceous sorbent of d means for disposing the contact batch of carbonaceous sorbent into contact with the products of fuel conversion at a contact location such that the carbonaceous sorbent of the contact batch adsorbs mercury; and transport means for transporting carbonaceous sorbent of the contact batch to the contact location in a manner in which, on average, at least ninety percent (90%) of the carbonaceous sorbent of the contact batch is delivered to the contact location in less than thirty (30) minutes following the separation of the carbonaceous sorbent of the starter batch into the carbonaceous sorbent of the contact batch and the carbonaceous sorbent of the retained batch, whereby the carbonaceous sorbent of the contact batch is disposed into contact with the products of fuel conversion at the contact location with substantially no intermediate storage of the carbonaceous sorbent following the conversion of the carbonaceous sorbent of the starter batch into the carbonaceous sorbent of the contact batch and the carbonaceous sorbent of the retained batch.
