Total Sulphur Content

The black soils of Adilabad and Nizamabad districts of Northern Telangana zone most prominent for the cultivation of soybean. From this region of soils, sixty soil samples were collected and analysed for available sulphur and its fractions. The results indicated that available sulphur content ranged from 5.9 mg kg-1 to 52.6 mg kg-1 with a mean of 13.8 mg kg-1. The available sulphur content was low to medium in status. The extent of sulphur deficiency of soybean growing areas of Adilabad and Nizamabad are 50 and 43.4 per cent respectively. The water-soluble sulphur ranged from 5.4 mg kg-1 in rural samples of Nizamabad to 7.3 mg kg-1 in sonala soils of Adilabad district. Whereas KH2PO4 and Heat soluble sulphur content ranged from 19.2, 29.6 mg kg-1 in Armoor village to 28.7, 37.3 mg kg-1 in Sonala village respectively.  The highest total sulphur content was recorded in soils of Adilabad district.

Pyrolytic Oil

Due to its high total sulphur content and other unfavourable properties, pyrolytic oil obtained as a result of tyres pyrolysis is not suitable for use as motor or heating fuel. Therefore, pyrolytic oil was hydrorefined. Hydrorefined oil was used as a component of light heating oil. A composition was prepared from 30 wt % hydrorefinate with 70 wt % Ekoterm Plus (a commercial oil). Unfortunately, the flash point temperature of the hydrorefinate was too low, and did not allow fuel compliant with the Polish standard PN-C-96024:2011 for L1 light heating oil to be obtained. Therefore, the fraction with boiling point below 180 °C was removed from the hydrorefinate. The residue, with a flash point of 74 °C and a sulphur content of 0.143 wt %, was mixed with Ekoterm Plus and fuels with a hydrorefinate fraction content of 30 and 50 wt % were prepared. The composition containing 30 wt % met the requirements for L1 oil in the whole range of tested parameters. Total sulphur content was 0.092 wt %, specific weight was 856 kg/m3 and closed cup flash point was 64 °C. However, the composition containing 50 wt % hydrorefinate did not meet the requirements regarding sulphur content and specific weight. Sulphur content, specific gravity, and flash point are the parameters limiting the possibility of using hydrorefined pyrolytic oil for composing light heating oils compliant with the mentioned standard.

Sulphate Sulphur

The current investigation was conducted to study the fractions of sulphur in nine districts of low and mid hills of Himachal Pradesh. For this purpose 31 representative soil sampling sites were selected from nine districts and the soil samples were analyzed for physicochemical properties and different fractions of sulphur (water soluble sulphur, exchangeable sulphur, available sulphur, non-sulphate sulphur, organic sulphur and total sulphur). The results indicated that the total sulphur in soils varied from 98.2 to 470.1 mg kg-1 in surface soil (0-15 cm) and 67.2 to 370.7 mg kg-1 in sub-surface layer (15-60 cm). The organic sulphur varied from 80.5 to 401.1 mg kg-1 in surface and 44 to 306.1 mg kg-1 in sub-surface layer. The water soluble sulphur, exchangeable sulphur, available sulphur and non-sulphate sulphur varied from 1.7 to 9.2, 2.7 to 18.4, 4.5 to 27.6 and 10.2 to 58.9 mg kg-1 respectively in surface soil and 0.5 to 5.4, 1 to 17.7, 3.7 to 23.5 and 12.5 to 50.2 mg kg-1, respectively in sub-surface soil. It was observed during course of study that with increase in the soil depth the content of different fractions of sulphur decreased. These soils had the major part of their total sulphur content in organic form followed by non-sulphate sulphur, available sulphur, exchangeable sulphur and water soluble sulphur. It can be concluded that the soil texture and organic carbon content played a major role in determining the quantity of different fractions of sulphur in these soils.

SUMMARYField experiments were carried out to study the effects of elemental sulphur on irrigated groundnut. The sulphur was applied at rates of 50, 100 or 150 kg ha−1, either at sowing, at flowering or in two equal splits at sowing and flowering. Shoot dry weight, total sulphur content of leaves, nodule number per plant and pod yield were all significantly increased by sulphur treatment, but nodule dry weight was unaffected. The greatest response lay at or below 50 kg ha−1 applied at sowing. There were no further increases in response above this level.

Streszczenie Dokonano charakterystyki zmian zawartości siarki całkowitej w 29 pokładach węgla kamiennego złóż Pniówek i Zofiówka, występujących w monoklinie Zofiówki - obszarze o podstawowym znaczeniu dla pol- skiej bazy węgli koksowych. Wytypowane do badań pokłady reprezentują warstwy siodłowe, rudzkie, załęskie i orzeskie, tj. pokłady gnip 500,400 i 300 (namur B - westfal B). Charakterystyki zmian S,d dokonano na podstawie utworzonej cyfrowej bazy danych obejmującej 2730 próbek, spośród których w 2661 oznaczono zawartość tego pierwiastka. Przeprowadzono podstawowe analizy statystyczne, za pomocąktórych określono m.in. liczbę próbek, w których oznaczono zawartość siarki całkowitej w poszczególnych pokładach, a także min., maks. oraz średnią zawartość tego pierwiastka w danym pokładzie. Prześledzono zmiany zawartości siarki całkowitej w układzie wertykalnym (wraz z głębokością) i horyzontalnym (w dwóch kierunkach: E-W oraz N-S). Wykreślono także mapy izoliniowe zawartości siarki całkowitej we wszystkich badanych pokładach węgla. Wyniki badań wykazały, że zawartość siarki całkowitej w badanych pokładach złóż monokliny Zofiówki zmienia się w zakresie od 0,21% S,d w pokładzie 406/1 do 2,18% S,d w pokładzie 361. Zawartość średnia siarki całkowitej w złożach monokliny Zofiówki wynosi 0,65% S,d. Nie wykazano żadnej ogólnej tendencji zmian zawartości siarki cał- kowitej. W każdym z pokładów obserwuje się odmienny charakter tych zmian. Przedstawione w artykule rezultaty stanowią część wyników uzyskanych w ramach projektu badawczego pt.: „Inteligentna koksownia spełniająca wymagania najlepszej dostępnej techniki”, opartego na współpracy nauki z przemysłem, realizowanego w ramach Programu Operacyjnego „Innowacyjna Gospodarka” i finansowanego w większości ze środków Europejskiego Funduszu Rozwoju Regionalnego.
