Abstract:
A side stream of a pilot gasification plant with a nominal input of 20-30 kg/h of feedstock was used. The raw syngas was conveyed through a thermally insulated line at 250°C to a cracking section consisting of two reactors in series each having a useful volume of 980 cm3. This configuration allows for the utilization of dolomite as a catalyst as well as a chemical trap for sulfur and chlorine compounds. The catalytic reforming war carried out following a Design of Experiment built on a temperature range of 650 °C - 750 °C and GHSV in the range 3000 h-1 - 6000 h-1. The tested setup entailed passing raw syngas first through a bed of dolomite to take advantage of first, even if not complete, tar conversion. Immediately after, the partially cleaned syngas passed through a bed of the novel tar reforming catalyst C&CS #1250 A. The syngas was sampled at the exit of the gasifier and at the exit of the catalytic unit for offline analysis of water and organic volatiles following the CEN/TS 15439:2006 procedure and using HPLC and GC-MS. The tar contained in the stream of syngas, in the order of up to 100 g/Nm3, was efficiently reformed down to few tens of mg/Nm3.
