However, the yield of saturated hydrocarbons during hydroprocessing of refined UCO (r-UCO) can be lowered by the formation of oligomers via double bonds present in unsaturated TAG and via those produced by dehydration of hydroxy groups of MAG and DAG and β-elimination of (un)saturated TAG. Herein we attempted firstly to remove polar substance from the r-UCO through liquid–liquid extraction and secondly to pre-hydrogenate unsaturated fatty acid chains before the main hydroprocessing reaction. The first attempt was effective for reduced oligomer formation in batch-mode experiments but not in continuous-flow ones. The other attempt was to prove very successful in both modes of experiments regardless of the presence of polar substances in r-UCO; thus, continuous-flow hydroprocessing of r-UCO could be sustained for 100 h without oligomer formation. Consequently, coupling pre-hydrogenation with main hydroprocessing is very powerful in maximizing the yield of hydrocarbons from the conversion of r-UCO because removing polar substances is meaningful but not economic.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"42 1","pages":"57 - 69"},"PeriodicalIF":2.9,"publicationDate":"2024-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142906067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Encapsulation techniques using polymers, silica, and phospholipids have shown promise in maintaining PQD stability in aqueous solutions.

The co-digestion of M and TR significantly enhanced the biogas and methane production performances, with an increase of 27.5–173.2% compared to mono-digestion. The ratio of M to TR affects the total solid (TS) load in the initial AD process. A TS greater than 3% was found to be more favorable for methane production. This co-digestion method avoids the accumulation of volatile fatty acids (VFAs) in the mixture which prevents inhibition of methane production. The effect of initial substrate and inoculum concentration in two-stage AD using dried CPH powder was also explored in this study.
