Abstract

Cattle manure was hydrothermally carbonized in acid solutions (0-2% HCl), then nutrient concentration in liquid product and physicochemical properties of hydrochar were characterized to investigate the effects of acid addition on hydrochar properties and nutrient recovery from manure. Results showed that hydrothermal carbonization (HTC) in 2% HCl extracted almost 100% and 63.38% of phosphorus and nitrogen, respectively; specifically, >90% of the extracted phosphorus was PO 4-P in liquid from HTC with acid addition, and increasing amount of extracted nitrogen was NH 4-N with increasing acid addition. Generally, higher heating value, surface area, total pore volume, fixed carbon, atomic ratios of H/C and O/C were increased in hydrochars from HTC with acid addition, while yield, volatile matter, contents of nitrogen, sulfur and oxygen of these hydrochars were decreased. These results indicated that HTC with acid addition could simultaneously facilitate nutrient recovery from manure and resulting hydrochar upgradation.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In Dai et al., increasing acid concentration up to 2% increased the specific surface area by up to 75% and extracted almost 100% of phosphorous and 63.4% of nitrogen.

    “When increasing the acid concentration up to 2%, the specific surface area increased by up to 75%, which also extracted almost 100% of phosphorous and 63.4% of nitrogen.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
