Production of Renewable Diesel Fuel via Hofer-Moest Decarboxylation of Free Fatty Acids
… to biodiesel, this fuel product has better heating values and cold flow properties but demonstrates worse oxidative stability. An advantage of this electrochemical process is the robustness of feedstocks that can be used, which includes algae oils, high FFA wastes such as brown and yellow …

Variables Governing the Initial Stages of the Synergisms of Ultrasonic Treatment of Biochar in Water Saturated with Carbon Dioxide
… above the solution. The changes in biochars’ heating values, carbon and hydrogen contents, internal surface area, and pore size distribution have significant technological implications and are the focal points of this study. The miscanthus and switchgrass biochars were produced via pyrolysis …

Hydrothermal liquefaction of microalgae: Influence of varying cell compositions on biocrude yield and quality
… of the biomass. Biocrude yields and higher heating values (HHV, MJ/kg) both increase with increasing FAMEs content, leading to higher energy recovery within the biocrude product phase. Increasing FAMEs content also leads to biocrude products with an increasing fraction of compounds with …

Evaluating the recyclability of wet-strength sacks and liquid packaging board through repulping
… rejects with fibre traces showed elevated higher heating values (39.65 MJ/kg), volatile matter (73.77%), and total carbon content (63%), indicating suitability for pyrolytic conversion into energy-rich products. WS Sacks filtrates exhibited high conductivity (>3000 μS/cm) and low pH (<5), …

Hydrothermal liquefaction for energy recovery from high-moisture waste biomass
… (e.g., oil yield, elemental analysis, higher heating value) and physico-chemical characteristics (e.g., molecular constituents, functional group allocation, proton and carbon speciation, molecular weight distribution, boiling point distribution) were compared for the varying feedstocks as well …

Upgrading hydrothermal liquefaction biocrude oil from wet biowaste into transportation fuel
… algal biomass (AW) appeared to reduce the higher heating value (HHV) and hydrocarbon compositions in the biocrude oil. To resolve this issue, physical pretreatments on AW biomass were carried out to decrease the ash content and improve the biocrude oil quality. AW biomass with different ash …
