Application of Lignosulfonates to Reduce Waste of Spent Ion-exchange Catalysts in Petrochemical Production
https://doi.org/10.18412/1816-0395-2022-1-4-8
Abstract
The paper considers ways to reduce industrial waste of spent cation exchange catalysts by pre-purification of hydrocarbon raw materials from catalytic poisons with lignosulfonates. The indicators for evaluating the effectiveness of lignosulfonates are highlighted, the normalized values for ensuring the quality of purification are indicated. To achieve the results of purification, optimal conditions for the preparation of primary lignosulfonate compounds are shown. Taking into account the duration of decomposition of waste cation exchange catalysts, the efficiency of large-scale implementation of the results obtained is evaluated, ways of significantly increasing the duration of operation of ion exchange catalysts are indicated. Catalytic poisons are captured by biodegradable lignosulfonate, which can be reused as components of drilling fluids or regenerated for re-filtration from catalytic poisons.
