Publication number: 20100215559Abstract: A method for producing extremely pure amorphous boron, wherein a reducing gas and a gaseous boron halide are introduced continuously or quasi-continuously into a reaction chamber (10; 32) of a reactor (8; 9; 30; 42) during its operation, wherein a surface of a catalyst (15; 20; 37) is provided in the reaction chamber (10; 32) of the reactor (8; 9; 30; 42), which supports the reaction of the boron halide to form boron; and wherein the boron that is deposited on the surface of the catalyst (15; 20; 37) is regularly mechanically removed such that the removed boron is available in the form of powder in the reaction chamber (10; 32) of the reactor (8; 9; 30; 42). The method produces extremely pure amorphous boron which already has a very small grain size without downstream disintegration of the extracted boron. The use of boron powder produced in this fashion is proposed, in particular, for the superconductor production in the magnesium boron system due to the improved current carrying capacity.Type: ApplicationFiled: February 18, 2010Publication date: August 26, 2010Applicant: Bruker HTS GmbHInventors: Andrè Aubele, Bernd Sailer

Patent number: 7736491Abstract: A process for the fluid catalytic cracking of mixed hydrocarbon feeds from different sources is described, such as feeds A and B of different crackability, the process being especially directed to obtaining light fractions such as LPG and comprising injecting feed A in the base of the riser reactive section and feed B, of lower crackability, at a height between 10% and 80% of the riser, with feed B comprising between 5% and 50% of the total processed feed. The process requires that the feeds present differences in the contaminant content, improved dispersion of feeds A and B and feed B injection temperature same or higher than that of feed A.Type: GrantFiled: May 19, 2004Date of Patent: June 15, 2010Assignee: Petroleo Brasileiro S.A. - PetrobrasInventors: Claudia Maria de Lacerda Alvarenga Baptista, Henrique Soares Cerqueira, Emanuel Freire Sandes

Publication number: 20100068113Abstract: Phosphorous ions are extracted (210) from solutions by adsorbing phosphorous ions in a scavenger and by releasing the phosphorous ions into an eluate during regeneration (230) of the scavenger. The regeneration (230) is performed by ammonia. Phosphate anions are precipitated (262) in form of tri-ammonium phosphate upon introduction (260) of excess amounts of ammonia. The ammonia remaining in solution after the precipitation of tri-ammonium phosphate is reused (266) for regenerating the scavenger.Type: ApplicationFiled: January 4, 2008Publication date: March 18, 2010Applicant: EASYMINING SWEDEN ABInventor: Yariv Cohen
