Abstract: The present invention relates to the use of a comparatively cheap material for the containment of at least a strongly acidic mineral acid solution highly diluted with water, by means of which saccharides are extracted from lignocellulose material by hydrolysis at a temperature of 175-240° C. and a pressure of 6-34 bar (0.6-14 MPa) as well as a time of 1-60 minutes and is characterized in that the material comprises, in addition to iron in an amount greater than any other individual substance and usually at least 50% by weight, at least chromium in an amount of 10.5-30% by weight, nickel in an amount of 2.5-29% by weight, and molybdenum in an amount of 0-7% by weight. The invention also relates to an apparatus.

Abstract: The present invention relates to a methods, products and uses for inhibiting corrosion. A provided method comprises the steps of: a) subjecting cellulosic biomass to hydrolysis to obtain a hydrolysate liquid; b) optionally, subjecting the hydrolysate liquid from step a) to one or more of the steps of further hydrolysis, fermentation and/or distillation; and c) using the hydrolysate liquid from step a) or b) to inhibit corrosion.
