Description

Reference product: synthetic gas [m3]
Location: RoW - Rest-of-World
Composition (% mol.) of the resulting gas is 28.4% H2, 40.6% CO, 23.6% CO2, 5.9% CH4 and 1.5% CnHm (mol.) on a nitrogen and water free basis. Nitrogen content is 47.6%. Density is 1.15 kg/Nm3. Lower heating value of the gas is 5.2 MJ/Nm3. Heat is supplied by syngas combustion. Inventory refers to the net production of 1 Nm3 syngas. Net gas yield is 1.922 Nm3/kg of wood (dry matter).

[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]

Technology

The technology corresponds to an average indirectly heated, atmospheric Fixed bed gasification, followed by a low temperature wet gas treatment. No energy integration with the subsequent processing of the gas is considered. The Fixed bed gasification plant is typically <2 MWth input capacity.
