Title:
OIL-CONTAINING SLUDGE TREATMENT METHOD, SOIL REMEDIATION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/193419
Kind Code:
A1
Abstract:
The present application provides an oil-containing sludge treatment method and a soil remediation method. The oil-containing sludge treatment method comprises: uniformly mixing an oil-containing sludge with a target biochar according to a first preset mass ratio, then performing a catalytic pyrolysis reaction at a first preset temperature, to realize efficient removal of petroleum hydrocarbons and obtain pyrolysis residues for soil remediation. The method provided by the present application achieves reclamation and harmless utilization of pyrolysis residues.
