Abstract. Co, Mo, NiMo and CoMo catalysts supported on alumina, fishbone and platelet carbon nanofibers (CNFs) have been prepared. The dispersion of the oxide phases was qualitatively studied and compared using Xray diffraction (XRD) and transmission electron microscopy (TEM). The reducibility of the catalysts was studied by temperature programmed reduction (TPR). Hydrodesulfurization (HDS)…
Rice growth and its resistance to pests had been often constrained by soil-silicon (Si) availability.The purpose of this study was to assess the potential of biochar soil amendment (BSA) to improve Si availability in paddy soils. A cross-site field trail with BSA was conducted in six locations with different climatic and crop-production conditions across S China. Plant-available Si content befo…
