Thermodynamics of hydrogen sulfide adsorption in Zeolite Lix

چکیده

Sulfur compounds adversely affect the technological process of oil and gas refining, as well release sulfur-containing into atmosphere, polluting environment. Oil processing is carried out using microporous adsorbents with high sorption capacity in purification gases containing sulfur. This one most efficient methods refining processing. In research work, adsorption sulfur their composition various ways. When determining formation complex, main centers Li-ionic molecules, it was possible to obtain a more accurate idea mechanism at stages absorption hydrogen sulfide molecules Li-zeolites highly sensitive calorimeter. our study, on LiX zeolite, results differential heat, isotherm, entropy, thermal equilibrium time (thermokinetics) based obtained vacuum device are accurately revealed. Based exact formulas, proved how many adsorbed zeolite that died under conditions.

Adsorption of Hydrogen Sulfide at low temperature

From an ecological perspective is biogas an important source of energy. It is produced from fermentation of organic material, e.g. household waste and wastewater sludge. The composition of the gas depends on the raw material and varies between 65-85% methane, 15-35% carbon dioxide and small amounts of ammonia and hydrogen sulfide. To use the biogas it is important to purify it from hydrogen sul...

The Suicide Pandemic of Hydrogen Sulfide Poisoning in Japan

Background: Hydrogen sulfide (H2S) suicides have been frequent in Japan in recent years. This study was performed to describe the epidemiologic profile of an outbreak of H2S suicides in Japan. Methods: In September 2008, questionnaires about patients involved in H2S suicides were sent to 250 hospitals in Japan. Data collected from each patient included gender, age, clinical manifestations, date...

Lix@C60: Calculations of the Encapsulation Energetics and Thermodynamics

Li@C(60) and Li@C(70) can be prepared and thus, their calculations at higher levels of theory are also of interest. In the report, the computations are carried out on Li@C(60), Li(2)@C(60) and Li(3)@C(60) with the B3LYP density-functional theory treatment in the standard 3-21G and 6-31G* basis sets. The computed energetics suggests that Li(x) @C(60) species may be produced for a few small x val...

Thermodynamics and Mechanism of Nicotine Adsorption onto Hydro- Phobic Zeolite Type Usy from Aqueous Solution*

The isothermal adsorption of nicotine from an aqueous solution onto zeolite type USY at temperature range from 298 to 322 K was investigated. It was found that the adsorption isotherms can be described by the Freundlich adsorption isotherm. The density distribution function of adsorption centers has an exponential form and the adsorption isotherms can be fitted by the Freundlich isotherm. The c...
