Sulphuric acid is also coveted by sewage treatment plants, as well as the metal, mining, wood-pulp and leather processing industries. Repurposing sulphur into eco-friendly products Beyond conventional applications, scientists are exploring sustainable and eco-friendly uses for sulphur. With sulphur...
A novel non-metallic element of the sulphur group is named, "sulphenium". It is present in diamond, together with carbon. Its presence is shown by reacting pure Fe with diamond, and treating the product with an acid, yielding a gaseous cpd. with properties similar to H2S, but giving a...
Several synthetic and naturally occuring metal sulphides react with the system dimethyl sulphoxide–sulphur dioxide to give metal hydrogen sulphates or sulphates, in contrast with the reaction of sulphides with aqueous sulphur dioxide, which yields mainly thiosulphate. 展开 DOI: 10.1039/C39880000728 ...
options when it comes to crafting. A potion asking for something verdant can be brewed from moss, leaves, or herbs. One asking for something sinister would work with a bat wing or an old metal chain. Whatever you find, can be used in some way. There is no such thing as "useless ...

In all the cases, the deactivation is caused by the reaction of SO2 with the metal, altering the structure of the material or forming metal sulphates. However, the wide variety of oxides studied, chemical types (single or complex oxides), and supports (bulk materials and metal oxides on ...
Sulphur is referred to as a multivalent, abundant, tasteless and odourless non-metal that naturally occurs near volcanoes. The major allotropic forms or types of sulphur include Rhombic sulphur (α-sulphur), Monoclinic Sulphur (β-sulphur), Colloidal Sulphur, and Milk of Sulphur....
Hydrodesulphurisation of a non-metal contg. vacuum or virgin gas oil or thermal or catalytic cycle oil is effected in the presence of a catalyst contg cpds. of metals of Gp VI B and/or VIII and 0.1 - 15 wt% pref 0.5 - 10 wt % of a Gp V B metal, pref. V, with injection of...
One class of compounds generally employed to neutralise the acidic materials and disperse sludge within the lubricating oil are the sulphurised metal alkyl phenates, wherein the metal is an alkaline earth metal such as calcium, magnesium or barium. Both "normal" and "overbased" sulphurised alka...
