National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Continuous Operation of Spray-Dried Zinc Based Sorbent in a Hot Gas Desulfurization Process Consisting of a Transport Desulfurizer and a Fluidized Regenerator.

Abstract	We see the sorbent reaction performance in a HGD process consisting of a transport desulfurizer and a fluidized regenerator in this study. We have obtained the solid hold-up and solid circulation rate necessary to reach the target desulfurization efficiency. A major obstacle for fluidized- or transport bed sorbent developments is sorbent durability withstanding attrition. Continuous operation only makes similar conditions of real processes such as rapid temperature swing, chemical transformations between sulfidation and regeneration, stresses induced by fluidization and continuous particle circulation between two reactors. Therefore, an integrated system of transport desulfurizer and bubbling regenerator is operated continuously more than 150 hours to see system reliability, sorbent reaction characteristics, sorbent morphology before and after test.
