Apr 23, 2023 · Using the alkaline oxide MgO as the body catalyst, different metal salts and metal oxides are doped or loaded to adjust the acidity or alkalinity strength of their surfaces, and the generation selectivity for different reaction products is facilitated.

Jun 5, 2017 · Using breakthrough experiments, UiO-66, Mg-MOF-74, and MIL-101 (Cr) were screened out to present promising performance on the H 2 S capture. The present study is useful to identify and design suitable MOF materials for high-performance H 2 S capture and separation. To access this article, please review the available access options below.

Jul 8, 2024 · It has been found that under the same reaction conditions thermal catalytic reaction between H2S and CO2 mainly generates COS, while the reaction pathway changes under the irradiation of light. Photo...

Apr 15, 2019 · To improve the removal of H 2 S and recovery of sulphur resources at ambient temperature, we designed novel core–shell-structured H 2 S imprinted polymers (PMo 12 @UiO-66@H 2 S-MIPs) based on the surface of UiO-66 modified by phosphomolybdic acid hydrate.

One of the most significant issues that may force the need for removing H2S from EOR CO2 is pipeline requirements. Many (but not all) CO2 supply pipelines that serve EOR areas have a specification for H2S; a range of 10 – 100 ppmv is common.

Dec 15, 2022 · Herein, unsupported CoMo sulfide catalysts with abundant sulfur vacancies were fabricated to attain synergistical conversion of H2 S and CO 2 to COS. Various metal sulfides were obtained, such as Co3 S 4, Co 9 S 8 and vacancy-defective MoS 2.

Feb 7, 2018 · CO2 and H2S are traditionally deemed useless or even harmful gases in natural gas. A solar-driven electrochemical approach was used for the coupled conversion of CO 2 and H 2 S into CO and S with high activity and stability at near neutral conditions.

In this research, 1-butyl-3-methylimidazolium bromide [bmim] [Br] ionic liquid was analyzed as a hydrophobic solvent with has high selectivity to H 2 S as an environmentally friendly solvent to absorb acid gas from natural gas with low H 2 S/CO 2 …

H2S + CO2 = COS + H2O is a Double Displacement (Metathesis) reaction where one mole of Hydrogen Sulfide [H 2 S] and one mole of Carbon Dioxide [CO 2] react to form one mole of Carbonyl Sulfide [COS] and one mole of Water [H 2 O] Thermodynamics of the reaction can be calculated using a lookup table. ΔS = S products - S reactants.

Dec 20, 2018 · Herein, the first observation of CO2 reduction to formate with H2S under alkaline hydrothermal conditions is reported, and water is found to act as a hydrogen donor.
