Abstract: Wound healing is a process by which these wounds on the skin of a subject heal and eventually close. When the injured surface is large, becomes infected, or in patients with poor healing capacity such as diabetics or the elderly or bedridden patients, then wound healing can be prolonged and lead to chronic ulceration and further complications with even limb loss or increased morbidity and mortality. This invention is directed to a topical formulation for promoting wound healing, and wound dressings and bandages comprising the same.

Abstract: The present invention discloses a process for preparing sulfur from reduction of sulfate/nitrate by iron-carbon and recovering desulfurization/denitration agents. High-concentration SO2 flue gas produced by calcination of a sulfate and NOx produced by heating decomposition of a nitrate can be directly reduced to elemental sulfur vapor and N2 through reaction with an iron-carbon material at a high temperature. Then, after dust removal, cooling and fine dust removal, sulfur is recovered by a sulfur recovery device, and metal oxides can replace alkaline mineral resources such as limestone as raw materials of desulfurization (denitration) agents. This process can recycle the desulfurization and denitration agents.
