METHOD OF PRODUCING H2 AND/OR BR2 BY ELECTROLYSING HBr USING FLUOROPOLYMER MEMBRANES

A method of producing hydrogen and/or bromine by electrolysing hydrogen bromide using a fluoropolymer membrane having a glass transition temperature T.sub.g110 C. in an electrolysis of hydrogen bromide, wherein the hydrogen bromide stems from a sulfuric acid synthesis.

Modified sulfuric acid and uses thereof

A one-pot process to separate lignin from a lignocellulosic feedstock, where the process involves the steps of: providing a vessel; providing the lignocellulosic feedstock; providing a composition that includes: an acid; a modifying agent including a compound containing an amine group; and a peroxide; exposing the lignocellulosic feedstock to the composition in the vessel for a period of time sufficient to remove at least 80% of the lignin present in the lignocellulosic feedstock; and, optionally, separating and removing a liquid phase that includes dissolved lignin fragments from a solid phase containing cellulose fibres.

Use of sulfur as alternative carbon-free fuel in ammonia primary reformer combustion zone, by coupling ammonia and sulfuric acid production facilities

A novel integrated system utilizing sulfur as alternative carbon-free fuel in an ammonia primary reformer combustion zone, with co-production of sulfuric acid from concentrated SO.sub.2 off-gas stream. Such integration shall reduce hydrocarbon fuel consumption, minimize CO.sub.2 emissions, and optimize overall energy utilization.
