Description

Location: RER - Europe
This dataset represents the production of 1 kg of hydrogen peroxide. Hydrogen peroxide is a colourless liquid with a slightly sharp odour at higher concentrations. Due to its characteristics as a strong oxidising agent, hydrogen peroxide is widely used as a bleaching agent in the paper and the textile industry. Further important uses are e.g. wastewater treatment, disinfection applications or hydrometallurgical processes. In dilute solutions H2O2 acts as a very efficient antiseptic.
This dataset is based on a study performed by EMPA and Boustead Consulting, commissioned by CEFIC, and contains data from 8 European producers of hydrogen peroxide.

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.

Technology

The most common technique for the production of hydrogen peroxide is the autooxidation (AO) or anthraquinone process. In a first step, hydrogen peroxide is produced by reducing alkylanthraquinone with hydrogen in the presence of a catalyst to the hydrochinone. Then the catalyst is removed and the hydrochinone is oxidised – usually with air – back to the origin quinone and in the same time hydrogen peroxide is produced. The quinones can then be re-hydrolysed again. The whole reaction takes place in a working solution that consists of a mixture of various solvents (i.e. parts are aromatic solvents). The whole process is exothermic. In a second step, hydrogen peroxide is extracted from the working solution and concentrated. Both steps are included in this dataset.
