Abstract:
L'invention concerne un procédé et une unité de traitement d'un digestat extrait d'un digesteur d'une installation de méthanisation. Selon l'invention, un tel procédé comprend: une étape de mélange d'au moins la fraction liquide dudit digestat avec une matière d'origine essentiellement minérale comprenant une quantité substantielle d'argile, de zéolithe et/ou de terre de diatomées, pendant une durée suffisante pour permettre un piégeage au moins partiel par ladite matière de l'azote ammoniacal sous forme ionisée contenue dans ledit digestat; une étape de séparation de la fraction solide dudit mélange.
Abstract:
Embodiments of the invention are directed to pelletized synthetic gypsum and methods and systems for producing pelletized synthetic gypsum. Synthetic gypsum is combined with a binder composition and pelletized to a desired size. The binder composition may include lignosulfonate. Additives may be included in the pellets such as various plant nutrients and micro-nutrients. An additive may include elemental sulfur. The resulting pellets may have a mean pellet size guide number (SGN) from approximately 150 to approximately 300 and a crush strength from approximately 2 Ibf to approximately 12 Ibf.
Abstract:
The present invention relates to a chelated fertilizer composition for enriching Zinc and Phosphorus content in agriculture/horticulture crops and plants through foliar application. The chelated fertilizer composition can be prepared using compounds comprising (a) Na2 HEDP and ZnSO4.H2O (Zinc sulphate monohydrate) and (b) Na2 HEDP and ZnO (Zinc Oxide). The chelation of Zn by Na2 HEDP using ZnSO4.H2O developed 17% Zn-HEDP and 21% Phosphorus pentoxide (P2O5) and chelation of Zn by Na2 HEDP using ZnO developed 21% Zn-HEDP and 26% P2O5. The chelated fertilizer composition obtained is in powder form and is 100% water-soluble concentrate. The chelated fertilizer composition can be used to cure Zinc and Phosphorus deficiency in crops and plants, increase yield with more Zinc and Phosphorus content, thus reducing the risk of Zinc and Phosphorus deficiency in humans.

The present invention relates to the field of material sciences. In particular, this invention pertains to production Kimberlite base products.
Abstract:
A method is disclosed for producing sulphate or phosphate-based fertilizer from hydrogen sulphide. The method involves feeding a stream containing a substantial volume of hydrogen sulphide and air to a furnace, where it is burned to produce a sulphur dioxide rich gas stream. The sulphur dioxide rich gas stream is then fed to a reactor to produce a sulphuric acid stream and a waste stream comprising carbon dioxide, nitrogen, oxygen, trace impurities and trace amounts of unreacted sulphur dioxide. The sulphuric acid stream is finally converted to a sulphate or phosphate-based fertilizer.
Abstract:
Tracers that can be used for PET or SPECT imaging of the distribution of Pgp are disclosed. The tracers are metalloprobes that can comprise a radioactive metal ion such as 67 Ga or 68 Ga. Methods of synthesizing the tracers, and methods of imaging heart and other tissues are also disclosed. The tracers can be used to obtain high signal-to-background ratios for imaging tissues in vivo such as heart or tumor tissue. In various embodiments, disclosed tracers can exhibit, a) enhanced first pass extraction into heart tissue compared to presently available probes, b) linearity with true blood flow, c) enhanced detection of myocardial viability compared to presently available probes, d) reduced liver retention compared to presently available probes, and e) more efficient clearance from non cardiac and adjoining tissues compared to presently available probes.
Abstract:
The present invention relates to processes for the production of microalgae, cyanobacteria and/or metabolites thereof. Described herein is a process involving the use of a stimulus applied to a microalgal or cyanobacterial culture to enhance the production of one or more metabolites. Also described herein, is a process for the production of microalgae and/or cyanobacteria comprising an adaptation stage wherein an algal/cyanobacterial culture is grown on a process water feedstock and/or under light emitting diodes (LEDs) emitting light within the spectrum of light wavelengths between around 400 nm and 700 nm, and a production phase, wherein the microalgae or cyanobacteria are grown on the same process water feedstock and/or under the same light conditions used in the adaptation stage. The invention also relates to specific microalgal strains.
Abstract:
The present invention relates to fertilizer products from Kimberlite having utility as nutrients to supply silica, magnesium, trace elements with or without organic substances, and also having scope to design products with various combinations with other fertilizers and/or plant based nutrients with or without nano structure.
Abstract:
Das Verfahren zur Herstellung von Phosphat- und Mehrnährstoff-Düngemitteln ist gekennzeichnet durch den Einsatz von aus der Monoverbrennung von kommunalen Klärschlämmen gewonnenen Aschen, die chemisch mit Mineralsäure, ein Phosphordüngemittel ergebend, aufgeschlossen werden und bei Zusatz von Kalium- und/oder eines Stickstoffträgers zum Phosphatdüngemittel ein Mehrnährstoff-Düngemittel hergestellt wird. Die Düngemittel besitzen eine granulierte Struktur, sind als ein NPK(S)-Dünger ausgebildet und können nach ihrer Herstellung direkt auf landwirtschaftliche Nutzflächen aufgebracht werden.
Abstract:
Изобретение относится к сельскому хозяйству, в частности, к растениеводству и может быть использовано в качестве средства для повышения урожайности любых сельскохозяйственных культур: зерновых, корнеплодных, овощных и др. В основу изобретения поставлена задача создания высокоэффективного удобрения путем введения в его состав компонентов, которые, за счет интенсификации процесса дифференцировки меристем, способствуют формированию наиболее эффективного морфотипа растений, это увеличивает количество и массу плодоэлементов растений, повышает урожайность и улучшает их потребительские свойства; кроме этого, за счет уменьшения времени на изготовление удобрения, упрощается технологический процесс приготовления удобрения и удешевляется его стоимость. Новым в изобретении является применение алюминия азотнокислого как усилителя действия азота и как системного активатора морфогенетических процессов растений, и удобрение, которое содержит алюминий азотнокислый, гидрохинон, ортованадат натрия и гидроокись калия, при следующем соотношении всех компонентов (масс. %): алюминий азотнокислый 78,40 - 99,598 гидрохинон 0,38 - 19,63 ортованадат натрия 0,003 - 0,006 гидроокись калия 0,016 - 1,966.
