Potential U.S. Production of Liquid Hydrocarbons From Biomass With Addition of Massive External Heat and Hydrogen Inputs

GCB Bioenergy, Journal Year: 2025, Volume and Issue: 17(2)

Published: Jan. 28, 2025

ABSTRACT We estimate the U.S. potential to convert biomass into liquid hydrocarbons for fuel and chemical feedstocks, assuming massive low‐carbon external heat hydrogen inputs. The is first a carbon feedstock only secondarily an energy source. This analysis done three estimates of available derived from 2023 Department Energy/U.S. Agriculture “Billion‐Ton Report” two augmented cases with maximum annual production 1326, 4791, 5799, 7432, 8745 million barrels diesel equivalent per year five cases. Constraints, such as assuring long‐term soil sustainability by recycling nutrients some back soils, result in being 70%–80% these numbers. currently consumes about 6900 year. Long‐term hydrocarbon consumption are between 50% 75% current consumption. External additions conversion processes are, respectively 25, 91, 111, 142, 167 tons system strongly negative because nutrient soils improve productivity.

Highly Efficient Recovery of Phosphate from Water Using Cerium Carbonate Hydroxide-Decorated Magnetic Biochar: A Slow-Release Phosphate Fertilizer for Agricultural Reuse

ACS ES&T Engineering, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 9, 2024

Phosphate removal plays a pivotal role in alleviating eutrophication and maintaining water quality. Cerium (Ce) demonstrates considerable promise phosphate removal, attributed to its strong affinity for ions. This study provides dual utilization strategy synthesizing Fe2O3- CeCO3OH-decorated hydrophilic porous biochar (Fe/Ce@HPBC), designed recovery from eutrophic waters followed by application as slow-release fertilizer. Fe/Ce@HPBC possessed excellent adsorption quantity, achieving maximum uptake of 203.88 mg/g accordance with the Sips model. Furthermore, experiment demonstrated that used fertilizer after could sustainably release 39.8% content within 28 days. Fe/Ce@HPBC-P also significantly increase effective phosphorus soil 65.51% promote maize seedlings 70.36%. Mechanistic investigation revealed outstanding was formation inner-sphere complexation through ligand exchange between Ce(HCO3)2+/Ce–OH, addition electrostatic attraction caused enhanced surface protonation. Overall, this contributes advancement techniques promotes development sustainable agriculture presenting an mitigating eutrophication.

Potentially toxic elements in human scalp hair around China’s largest polymetallic rare earth ore mining and smelting area

Environment International, Journal Year: 2023, Volume and Issue: 172, P. 107775 - 107775

Published: Jan. 25, 2023

There is a growing concern about human health of residents living in areas where mining and smelting occur. In order to understand the exposure potentially toxic elements (PTEs), we here identify examine cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb) zinc (Zn) scalp hair area (Bayan Obo, n = 76), (Baotou, 57) reference (Hohhot, 61). total, 194 samples were collected from volunteers (men 87, women 107) aged 5–77 years old three areas. Comparing median PTEs levels between young adults, Ni significantly higher adults while Cr was highest area, no significant difference found for any area. From linear regression model, relationship concentration, log10(PTEs), age found. The concentrations Ni, Cd, Pb lower when compared both addition, Cu Factor analysis (FA) indicated that men (Baotou) Obo), respectively, had different underlying communality suggesting sources these PTEs. Multiple factor quantilized importance gender location combined with hair. results this study indicate people and/or have (Cu, Pb) areas, which may cause adverse effects.

Reduction and Reuse of Forestry and Agricultural Bio-Waste through Innovative Green Utilization Approaches: A Review

Forests, Journal Year: 2024, Volume and Issue: 15(8), P. 1372 - 1372

Published: Aug. 6, 2024

Biomass waste, which is biodegradable and vastly underutilized, generated in huge quantities worldwide. Forestry agricultural biomass wastes are notable for their wide availability, high yield, biodegradability, recyclability. The accumulation of these not only occupies valuable land but causes serious environmental pollution, can ultimately harm human health. Therefore, leveraging scientific technology to convert forestry bio-waste into bioenergy other products crucial. In this paper, common such as straw, rice husks, livestock manure, tree branches, sawdust, (bioethanol, biogas, biodiesel, biohydrogen) were selected keywords, with the theme green efficient utilization. This paper provides a comprehensive review sources existing recycling technologies, potential material additives conversion energy derivatives, along future prospects.
