20150351317 | CONTINUOUS DRY PARTICULATE MATTER INJECTION DEVICE FOR FERTIGATION APPLICATIONS - The present invention relates to continuous dry particulate matter injection device ( | 12-10-2015 |
20150344762 | USE OF A CALCIUM POTASSIUM NITRATE SALT FOR THE MANUFACTURE OF A HEAT TRANSFER FLUID - The present invention relates to the use of a double salt of Ca(NO | 12-03-2015 |
20150210604 | UREA PASSIVATION TECHNIQUE AND NEW PRODUCT PASSIVATED UREA, TO MAKE UREA OR UREA-BASED COMPOUND UNIVERSALLY BLENDABLE - The invention concerns a method of producing passivated urea or urea based compounds for fertilizer blends wherein the urea particles are treated with a mineral acid that reacts with urea and creates a grasping layer. Thereafter a solid base in powder form is added in excess to the particles to coat the acidified particle surface. The invention also concerns a fertilizer blend comprising the passivated urea or urea based compounds with one or more of AN or AN-based compound, NS products, superphosphates, and more generally with a priori most compounds that urea is susceptible to react with when in direct contact. A safe blend comprises more than 40 weight % of the passivated urea. | 07-30-2015 |
20140318446 | METHOD AND DEVICE FOR PROCESSING OF GRANULES - A method for processing of granules, by forming at least one injection zone in a fluidized bed where a feed stream of seed particles is contacted or coated by a liquid product by simultaneous injection of the feed stream of the seed particles and a feed stream of the liquid product, forming at least one granulation zone in the fluidized bed where the contacted or coated seed particles may be at least one of dried, shaped, and cooled to form granules, extracting the granules from the at least one granulation zone and sorting the extracted granules into undersize granules, on-size granules, and oversize granules, passing the on-size granules to post-processing treatment, removing the oversize granules, and passing the undersize granules back into the feed stream of the seed particles, wherein the extracted granules are made to pass through at least one classifier located in the at least one granulation zone. | 10-30-2014 |
20130231241 | METHOD FOR PRODUCING CATALYSTS AND CATALYSTS THEREOF - The invention relates to a process to produce catalysts by powder injection moulding and the catalysts thereof, wherein the catalysts are made by preparing a ceramic formulation with temperature controlled rheological properties comprising catalytic components, heating the powder formulation up to at least the fluid state transition temperature, shaping a sample by injecting the fluid powder formulation into an injection mould followed by cooling the injected powder formulation below the fluid state transition temperature, de-binding the shaped sample, and sintering the shaped sample to form a ceramic catalyst. Alternatively the ceramic structure may be formed initially followed by a coating of the ceramic structure by one or more catalytic compounds. | 09-05-2013 |
20130220936 | METHOD TO SUPPORT AN EMISSION-FREE AND DEPOSIT-FREE TRANSPORT OF SULPHIDE IN SEWER SYSTEMS TO WASTE WATER TREATMENT PLANTS AND AGENT FOR USE THEREIN - The present invention concerns a method for the conditioning of septic waste water to prevent the formation of hydrogen sulphide and prevent subsequent precipitation of FeS, also provided is an agent for use in said method. The agent comprises an aqueous solution of iron salts and an anionic polymer. | 08-29-2013 |
