The history of the kraft pulping process is obscure, and few patents and stories try to explain the origin of this chemical pulping process. The story that most likely explain its origin goes back to the 1870s in a soda mill, where a chemical recovery plant operator made a mistake in the process of adding sodium carbonate (Na 2 CO 3) for …

The present study reports on ball-milling of high-surface-area graphite in the presence of sulfur, mainly considering high graphite/sulfur (G/S) weight ratios. Graphitic crystallites after co-milling with sulfur maintain essentially unaltered crystalline order while exhibit heavily functionalized lateral edges, mainly by O=S=O and S=O groups. Solvent …

7.3.1 CPO Production Process. As reported by Igwe and Onyegbado [], CPO comprises a fatty acid ester of glycerol, also known as triglycerides, which contributes to the global need for edible oils and fats.It consists of roughly 50% saturated fats (mainly palmitic acid) and 40% unsaturated fats. The fat-soluble carotenoids (pigments) in palm oil are …

The current industrial method for removal of sulfur from fuels is hydrodesulfurization (HDS), which is a high temperature, high pressure catalytic process. This makes HDS a very costly option for deep desulfurization. Moreover, HDS is not effective for removing heterocyclic sulfur compounds such as dibenzothiophene (DBT) and its derivatives, especially 4,6 …
