XRD Diffraction Spectrum: Single-Phase High-Purity γ-FeOOH Active Matrix
XRD Crystalline Phase Identification: Single Pure γ-FeOOH Phase (ICDD PDF #44-1415), Controllable Active Component Loading of 60–98 wt%
Objective Test Results
Full-range X-ray diffraction scans are referenced against the ICDD standard PDF Card No. 44-1415. All diffraction peaks generated from the sample align precisely with the characteristic signals of pure γ-FeOOH; no diffraction signals associated with inert impurity phases (α-FeOOH, iron oxides, mixed ferric hydroxides) are detected across the complete 2θ scanning range. Quantitative Rietveld refinement confirms the mass fraction of active γ-FeOOH can be precisely calibrated between 60 wt% and 98 wt%.
Corresponding Desulfurization Mechanism
Impurity crystalline phases exhibit minimal reactivity toward hydrogen sulfide, introduce competitive adsorption effects, and consume internal pore volume, all of which drastically reduce total sulfur retention capacity. Our single-phase γ-FeOOH crystalline matrix eliminates reaction inhibition originating from impurities, sustaining consistent intrinsic chemisorption activity under continuous high-throughput gas feed. High loading of pure, reactive γ-FeOOH provides abundant native reactive sites, establishing the fundamental chemical basis for high saturated sulfur capacity under field high-space-velocity operating environments.

Mixed impurity crystalline phases constitute a core performance drawback of conventional iron-based desulfurization media used for North American shale gas and high-temperature oilfield associated gas treatment across the Middle East. Inert impurity crystals suppress intrinsic H₂S chemisorption reactivity, occupy available adsorption void volume and trigger competitive adsorption, resulting in low saturated sulfur loading and constrained gas treatment throughput.
Our γ-FeOOH sorbent features a single-phase pure γ-FeOOH crystalline matrix with no detectable impurity phases, validated via full-range XRD scanning and quantitative Rietveld refinement. Tunable high loading of pure γ-FeOOH delivers abundant stable reactive sites to maintain superior sulfur retention capacity under continuous high-flow field operating conditions.

Page Exclusive Conclusion
The single-phase high-purity γ-FeOOH crystalline matrix avoids performance suppression caused by inert impurity crystals and maintains stable intrinsic chemisorption activity toward H₂S. When applied to high-space-velocity oil & gas purification projects across North America and the Middle East, this pure crystalline structure delivers far higher saturated sulfur loading than mixed-phase iron-based sorbents, lowering overall media consumption and long-term gas treatment operating costs for field operators.
