摘要：
Chromium-treated leather shavings are generated in large quantities by the leather industry. The biochar gasification from leather shavings leads to two main products, a hydrogen-rich syngas and a chromium-rich ash. Syngas has found different applications such as electricity generation and chemical manufacturing. The remaining ash potentially can be utilized, e.g., in stainless-steel production processes. The thermochemical conversion of biochar from chromium-tanned leather shavings via steam gasification was investigated. The cumulative gas yield and cumulative H-2 yield were determined as well as the total chromium as Cr2O3 in the remaining ash.
