The as-synthesized catalyst was characterized using XRD, ICE-AES, BET, SEM, FTIR and EDX. The clay catalysts were initially screened for fructose conversion and HMF yield and then K550-Cr, which showed the superior activity amongst the catalysts understudy, was chosen for further experiments. Various reaction parameters like reaction temperature and time, catalyst dosage, initial substrate concentration and catalyst reusability were studied in detail. The maximum HMF yield obtained was about 89 % at milder reaction conditions (130 ºC for 3h). The most interesting result was that the catalyst could be recovered easily without any loss and reused 4 times without loss in activity (HMF yield after 5th cycle was 88%).","PeriodicalId":9651,"journal":{"name":"Catalysis in Green Chemistry and Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135006724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The activity was highly sensitive to acidity and basicity of the catalyst. Hence the catalyst with maximum activity, calcium pyrophosphate, was modified with MoO3 for modifying its acidity and to study its effect on product selectivity for lactic acid dehydration. The MoO3 modified calcium pyrophosphate with 5% MoO3 loading was used for vapor phase dehydration of lactic acid at 375°C using 50% lactic acid concentration with WHSV of 3 h-1. The activity was compared with nonmodified calcium pyrophosphate catalyst. Surprisingly, deoxygenation was predominant compared to dehydration. Acidity was observed to play a crucial role in product selectivity (i.e,. with less acidic support, calcium pyrophosphate with 5 wt% MoO3 showed more deoxygenation activity as compared to acidic support γ-Al2O3 as well as SiO2 with same MoO3 loading). Higher acidity led to formation of acetaldehyde as the only product. The results confirmed formation of propionic acid by deoxygenation of lactic acid using in situ generated hydrogen after decarboxylation of lactic acid to acetaldehyde.","PeriodicalId":9651,"journal":{"name":"Catalysis in Green Chemistry and Engineering","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81162946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Absorbents from Jackfruit and coconut shells were synthesized at 550 °C for 4 h in the carbonization method and activated by acid treatment. Adsorbents synthesized from jackfruit and coconut shell waste were characterized by using techniques like BET, SEM, and XRD to study and compare their properties. This research concludes that jackfruit waste adsorbents act better than coconut shells and are similar to conventional ones. At adsorption parameters of 30 °C, pH= 7, 3-gram adsorbent quantity, reusable 3 times and a 24-hour contact period, for the absorption of dye and debris from wastewater jackfruit waste is preferable. Also, the qualities of traditional activated charcoal are contrasted with those of the jackfruit and coconut shell adsorbents. Purification of wastewater with jackfruit adsorbent was more than 96.3% as compared to coconut shell adsorbent with a 69.3% waste removal efficiency. The results demonstrated that jackfruit waste, due to its better structure, morphology and surface area would be the most effective adsorbent for removing methylene blue dye and contaminants from wastewater.","PeriodicalId":9651,"journal":{"name":"Catalysis in Green Chemistry and Engineering","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136053066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
