Hydrothermal liquefaction (HTL) is a promising technology for the production of bio-crude. However, some unresolved issues still exist within HTL, which need to be resolved before its promotion on commercial scale. The management aqueous phase one leading challenges related HTL. In this study, sewage sludge has been liquefied at 350 °C with and without catalyst (K2CO3). Subsequently, recycling was applied investigate effect bio-crude properties. Obtained results showed that energy recovery...
Wastewater treatment plant sludge contains large quantities of microplastics (MPs), which is a problematic substance that impedes sustainability efforts, such as in land management. MPs are resilient to degradation, but extreme conditions, high temperature and pressure, can lead residues be used fertilizers on farmlands. Hydrothermal liquefaction (HTL) creates converting into valuable bio-crude. To this end, the current study examined resilience sewage were treated by continuous HTL operated...
Hydrothermal liquefaction (HTL) of biomass is establishing itself as one the leading technologies for conversion virtually any type feedstock into drop-in biofuels and renewable materials. Several catalysis strategies have been proposed this process to increase yields product (biocrude) and/or obtain a with better properties in light final use. A number different studies are available literature nowadays, where catalysts utilized within HTL including both homogeneous heterogeneous...
Abstract This study demonstrates the economic feasibility of producing renewable transportation drop‐in fuels from lignocellulosic biomass through hydrothermal liquefaction and upgrading. An Aspen Plus ® process model is developed based on extensive experimental data to document a techno‐economic assessment scheme. Based 1000 tonnes organic matter per day plant size capacity, three different scenarios are analyzed identify key parameters minimum fuel selling prices (MFSP). Scenario I,...
In this study, hydrothermal liquefaction (HTL) of wheat straw (WS) in sub (350 °C) and supercritical (400 water with without alkali catalyst was performed to investigate the potential WS for production biocrude. The influences temperature were studied HTL products. Results showed that maximum biocrude yield (32.34 wt. %) least solid residue (4.34 obtained at subcritical catalytic condition, whereas carbon content slightly higher supercritical. heating value (HHV) is around 35 MJ/kg all four...
The aim of this paper is to evaluate the costs and GHG emissions advanced biofuels production through hydrothermal liquefaction (HTL) sewage sludge in Netherlands targeting marine fuels market. process evaluated consists a distributed configuration regional HTL plants co-located with wastewater treatment plants, centralized hydrotreating an existing refinery at Port Rotterdam. simulated ASPEN + based on published experimental data mass energy balances are used as input for techno-economic...
The use of sustainable biomass can be a cost-effective way reducing the greenhouse gas emissions in maritime and aviation sectors. Biomass, however, is limited resource, therefore, it important to where creates highest value, not only economically, but also terms GHG reductions. This study comprehensively evaluates reduction potential utilising forestry residue different bioenergy technologies using consequential LCA approach. Unlike previous studies that assess impacts per unit fuel...
To obtain drop-in fuel properties from 3rd generation biomass, we herein report the catalytic hydrotreatment of microalgae biocrude, produced hydrothermal liquefaction (HTL) Spirulina. Our contribution focuses on effect temperature, initial H2 pressure, and residence time removal heteroatoms (O N) in a batch hydrotreating setup. In contrast to common experimental protocols for at scale, devised set two-level factorial experiments studied most influential parameters affecting heteroatoms. It...
