This Small Business Innovation Research Phase I project will investigate the feasibilityof developing a technology to optimize accumulation and subsequent removal of a valuable element from integrated gasification combined-cycle (IGCC) systems. IGCC is a highly efficient, low-emissions technology that uses coal and other feed stocks to produce electricity, process heat, and high-value fuels and chemicals. Deposits containing a valuable metalloid accumulate in an IGCC system, requiring significant downtime forcleaning and loss of revenue. The proposed technology will lead to recovery of ametalloid as part of routine operation of IGCC systems. Metalloid capture will be performed using bench-scale laboratory equipment with a simulated gasification environment. Bonding mechanisms will be characterized to determine if spalling of deposits through thermal cycling and soot blowing is a feasible method of recovering deposits on-line.This innovation would substantially increase revenue by providing a marketable product stream and would decrease operating and maintenance costs by improving the efficiency of the system.

这个小型企业创新研究第一阶段项目将研究开发一种技术的可行性，以优化集成气化联合循环（IGCC）系统中有价值元素的积累和随后的去除。 IGCC 是一种高效、低排放的技术，利用煤炭和其他原料来生产电力、工艺热以及高价值燃料和化学品。含有贵重类金属的沉积物会在 IGCC 系统中积累，需要大量停机时间进行清洁并造成收入损失。所提出的技术将导致非金属回收，作为 IGCC 系统常规操作的一部分。准金属捕获将使用具有模拟气化环境的小型实验室设备进行。粘合机制将被表征，以确定通过热循环和吹灰进行沉积物剥落是否是在线回收沉积物的可行方法。这项创新将通过提供适销对路的产品流来大幅增加收入，并通过改善系统的效率。
