Integrated process for catalytic upgrading of hydrothermal liquefaction aqueous phase in the supercritical state

Frontiers in Chemical Engineering, Journal Year: 2025, Volume and Issue: 7

Published: March 14, 2025

Hydrothermal liquefaction (HTL) is a waste agnostic process that leverages near-critical water to break down macromolecules, forming an energy-dense biocrude. Some carbon contained in the feed lost aqueous phase, where its high organic content and unusual speciation are burdensome for municipal wastewater resource recovery facilities (WRRF). Treating phase adds undesirable cost HTL process, reducing attractiveness. Here, we report supercritical upgrading (AP-SCU) as new catalytic technology reduces of with co-production supplemental The provides sufficient catalyst activity conversion, energy inefficiency by eliminating need evaporation, extends lifetime relative liquid state. AP-SCU was evaluated at 380–440 ° C 24 MPa representative produced from treatment food waste. Using ZSM-5 bound silica sol, reduced 64%–73% corresponding production aromatic hydrocarbons including phenol 2-pentanone. total nitrogen approximately 10%. Additionally, facilitated reduction denitrogenation reactions compounds produce pyridine which more closely resemble After 3 h on stream, experienced coke formation, surface degradation led acid sites area. balance system closed through analysis aqueous, solid, gas phases estimate biocrude yield varies 43%–57% basis. An integrated showed operating unit 380 id="m2">° yielded minimum demand removal 63 MJ/kg-TOC. This value greater than conventional WRRFs (37.9 MJ/kg-TOC) but 10-times less emerging technologies designed handle complex feeds. has potential efficient effective TOC simultaneous offset demand.

Industrial Microbial Technologies for Feed Protein Production from Non-Protein Nitrogen

Microorganisms, Journal Year: 2025, Volume and Issue: 13(4), P. 742 - 742

Published: March 25, 2025

Due to the increasing global demand for feed protein, microbial protein has great potential of being able sustainably. However, application in animal cultivation industry is still limited by its high cost and availability on scale. From viewpoint industrial production, it vital specify crucial processes components further technical exploration process optimization. This article presents state-of-the-art technologies non-protein nitrogen (NPN) assimilation production. Nitrogen sources are one main factors media used large-scale fermentation. Therefore, available NPN synthesis, utilization mechanisms, fermentation corresponding strain reviewed this paper. Especially, random mutagenesis adaptive laboratory evolution (ALE) approach combined with (ultra-) throughput screening provided impetus increase yield. Despite underlying technological advances production extensive research development efforts required before commercial feed.

Shortening the Storage Duration of Food Waste and Adding Ammonia Nitrogen to Food Waste to Increase Hydrogen Yield in Microbial Electrolysis Cells

Energy & Fuels, Journal Year: 2024, Volume and Issue: 38(21), P. 20807 - 20816

Published: Oct. 23, 2024

Acidification occurs during the temporal storage and long-distance transportation of food waste (FW). It can influence FW physicochemical properties even subsequent treatment disposal. In this study, microbial electrolysis cells were constructed to evaluate hydrogen (H2) production biodegradation behaviors rice slurry (R) fermented liquid (FR). Carbohydrate, as main component in R, was more prone be acidified into acetate subsequently start H2 generation. While dominant FR butyrate, it became a rate-limiting step anaerobic fermentation, leading its lower productivity. Results showed that yield R 1.48 times higher than FR. The community molecular dynamics simulation revealed readily utilized by g_Aeromonas. This efficient pathway for producing H2. additional supply NH4+-N exerted remarkable effect on improving through enriching g_Geobacter g_Enterococcus. increasing g_Flavobacterium accelerated degradation starch generate
