A comparative investigation of methane hydrate formation from 0.1 wt % solutions an alkaline extract humic acids (HA) and sodium dodecyl sulfate (SDS) has been carried out. It was demonstrated that the grows as a voluminous loose mass squeezed onto reactor walls in both cases. turns about 75% water transforms into within 15–20 min. Thus, natural HA can act kinetic promoters. At same time, SDS increases nucleation rate compared to pure under studied conditions (12.5–13.0 MPa −5 °C), while...
Isothermal nucleation of methane hydrate in the emulsions water oil has been studied experimentally at a pressure 12.5 MPa within temperature range −3.0 to −4.9 °C (supercooling 17.8–19.7 °C). It was demonstrated that experimental survival curves are composed two regions with different slopes time axis. Nucleation rates calculated for initial and final (in parentheses) turned out be equal 0.00065 (0.00055), 0.00036 (0.00017), 0.00018 (0.00010) s–1 m–2 temperatures −4.9, −4.0, °C,...

Various adsorbents, including iodides and sulphides of some metals modified carbon materials, were synthesized their ability to recover mercury was studied. Our results showed that copper sulphide [dynamic capacity (DC) 36 mg/g for vapour], the active form manganese dioxide (DC 28 mg/g) adsorbents promising demercuration agents. The DC best agents (MNCS–O–Cl–I) can be as much 125 mg/g.
