dc.description.abstract | A ZnO-based sorbent, ZAC 32N, applicable to transport reactors was successfully prepared by the spray-drying technique. Another sorbent, ZAC 32SU, was prepared by scale-up preparation of ZAC 32N sorbent. The physical properties of the sorbents such as attrition resistance, specific surface area, pore volume, and particle size were extensively characterized and exhibited a good potential for use in transport applications. The chemical reactivity tested in the thermogravimetric analyzer and microreactor exhibited desirable characteristics for effective desulfurization of syngas streams in the range of 450-550 degrees C. Bench-scale tests for the sorbent ZAC 32SU were performed for a continuous 160 h with a steady solid circulation of 54.6 kg/h. The results showed 99.5%+ desulfurization at 500-550 degrees C and reasonable regenerability at 550-620 degrees C. Test results on the physical properties and chemical reactivity indicated that the performance of developed sorbents proved to be outstanding. | - |
