Methods of generating performic acid by contacting aqueous oxidizing agent and aqueous formic acid source in liquid phase are disclosed. A system and apparatus for the in situ production of the performic acid chemistries is further disclosed. In particular, a continuous flow reactor is provided to generate performic acid at variable rates. Methods of employing the oxidizing biocide for various disinfection applications are also disclosed.

Peroxyformic acid compositions for removal of biofilm growth and other contaminants and impurities from industrial processing hard surfaces are disclosed. In particular, peroxyformic acid compositions may be dosed on site and / or generated in situ for the reduction and prevention of biofilms on the hard surfaces. Methods of employing the peroxyformic acid compositions for removal of biofilm growth and other impurities such as aldehydes and alcohols from industrial CO2 effluent are also disclosed which beneficially provide ambient biofilm control and break down more rapidly than other peracids, allowing for extended runs between CIP cleaning, including a reduction and / or elimination of cleaning of the scrubbers and other industrial surfaces.

The invention discloses a furfural hydrogenation furfuryl alcohol modified copper-based catalyst preparation method, and relates to furfuryl alcohol. The method includes the steps: firstly, performingreaction on alkali metal salt modified agents and formic acid to form solution; secondly, regenerating a compound of copper salt and modified agent salt through hydrogen and carbon dioxide generatedby the formic acid in the decomposing process to form alkali carbonate modified copper-based catalyst. The prepared modified copper-based catalyst has high furfural conversion rate and furfuryl alcohol selectivity, and the yield of furfuryl alcohol can reach 80%-99% under suitable reaction conditions. Low-cost carbonate serves as a carrier or is doped into the catalyst, copper salt serves as a precursor, the copper-based catalyst with high activity is prepared by a simple in-situ reduction method, and furfural is catalyzed to prepare the furfuryl alcohol in a hydrogenation manner under the suitable process conditions. According to the furfural hydrogenation furfuryl alcohol modified copper-based catalyst, a preparation process is simple to operate, consumed time is short, cost is low, catalytic reaction activity is high, furfural selectivity is good, cycle performance is stable, and the catalyst has wide application prospects.
