Although the ERC process is not limited to use in the steel industry, a patented technology exists that claims the advantages of formic acid over the commonly used mineral acids for steel pickling.

Hot rolling processes (Figure 1) tend to produce an oxide layer on the surface of the steel strip. It is necessary to remove this layer – also known as ‘scale’ – prior to performing further processing ...

MIL-100(Fe) was prepared by mining useful resources from stainless steel pickling wastewater. And Q350-MIL-100(Fe) with hierarchical pores structure and abundant oxygen vacancies was obtained by ...

Recent technological developments in the electro-reduction of carbon dioxide to formic acid, a valuable chemical with possible application in the steel pickling process, may offer an alternative to ...
