摘要:
The present invention relates to a process for producing synthesis gas and at least one organic liquid or liquefiable material of value, wherein a) a biomass starting material is provided, b) the biomass starting material is subjected to a decomposition, c) at least one aromatics-enriched fraction C1) and at least one aromatics-depleted fraction C2) are optionally isolated from the decomposed material obtained in step b), d) the decomposition product from step b) or the aromatics-enriched fraction C1) from step c) is fed into a dealkylation zone and reacted in the presence of hydrogen and/or water vapor, e) a discharge is taken from the dealkylation zone and subjected to a separation to give at least one organic liquid or liquefiable material of value and at least one stream enriched in components which are more volatile than the organic material of value, f) the stream enriched in components which are more volatile than the organic material of value which is obtained in step e) is at least partly used for producing synthesis gas.
摘要:
The present invention relates to an integrated process for producing pulp and at least one organic liquid or liquefiable material of value, wherein a) a lignocellulose-comprising starting material is provided and subjected to digestion with an aqueous-alkaline treatment medium, b) a cellulose-enriched fraction and a cellulose-depleted black liquor are isolated from the digested material, c) the black liquor is subjected to a treatment to give at least one organic liquid or liquefiable material of value and at least one offgas stream, d) at least one of the offgas streams obtained in step c) is recycled to the process for producing pulp and utilized.
