Process design and techno-economic analysis of integrated coal gasification-flash ironmaking-methanol synthesis process by Hao Cheng, Guoqiang Cao, Zhongren Ba, Donghai Hu, Yongbin Wang, Jonas Baltrusaitis, Chunyu Li, Jiantao Zhao, Yitian Fang

“…In this work, a novel coal gasification, flash ironmaking, and methanol synthesis coupled process (CG-FI-MS) was proposed and designed to simultaneously obtain high-quality iron metal and methanol. The new process contains eight units: air separation, CG-FI, smelting reduction, water gas shift, acid gas removal, CO _2 compression, Claus unit, MS and purification unit. …”

Changes in soil organic carbon and aggregate stability after conversion to conservation tillage for seven years in the Huang-Huai-Hai Plain of China by Xin SHU, An-ning ZHU, Jia-bao ZHANG, Wen-liang YANG, Xiu-li XIN, Xian-feng ZHANG

“…In 2013, soil samples were collected at depths of 0–5, 5–10 and 10–20 cm, and separated into three aggregate-size classes: macroaggregates (>250 μm), microaggregates (53–250 μm) and the silt+clay fraction (<53 μm) using wet sieving method. Soil parameters measured were water-stable aggregates, geometric mean diameter (GMD), mean weight diameter (MWD) and OC concentrations in different aggregate-size fractions and in bulk soil. …”
