Recycling. Lead Recycling.

open access: yesShigen-to-Sozai, 1997
Because of the steady increase in car population and the mounting of enviromental concern, lead consumption ratio for lead-acid batteries is tending to gradually increase. As a result of this fact, itis important to establish new reliable collection, treatment, and recycling system of used lead-acidbatteries that would not to be effected by the ...

The kinetics of the methanol synthesis on a copper catalyst: An experimental study [PDF]

open access: yes, 1989
The kinetics of the low pressure of methanol from feed gases containing solely CO and H2 were studied in an internally recycled gradientless reactor. As experimental accuracy impeded the application of high CO contents, the experimental range of mole ...

Recovery of Residual Carbon from Ti-Extraction Blast Furnace Slag by Flotation with Simultaneous Dechlorination

open access: yesEnergies, 2022
Ti-extraction blast furnace slag (EBFS) is a secondary slag produced by titanium extraction of titanium-bearing blast furnace slag (TBBFS), which is challenging to be used directly because of its residual carbon and chlorine.

A new approach to recycle oxalic acid during lignocellulose pretreatment for xylose production

open access: yesBiotechnology for Biofuels, 2018
BackgroundDilute oxalic acid pretreatment has drawn much attention because it could selectively hydrolyse the hemicellulose fraction during lignocellulose pretreatment. However, there are few studies focusing on the recovery of oxalic acid.
