Patent number: 9327257Abstract: The present invention refers to a continuous process for in secco nanomaterial synthesis from the emulsification and detonation of an emulsion. The said process combines the simultaneous emulsification and detonation operations of the emulsion, thus assuring a production yield superior to 100 kg/h. When guaranteeing that the sensitization of the emulsion occurs mainly upon its feeding into the reactor, it is possible to avoid the accumulation of any class-1 substances along the entire synthesis process, thus turning it into an intrinsically safe process. Afterwards, dry collection of the nanomaterial avoids the production of liquid effluents, which are very difficult to process. Given that there's neither accumulation nor resort to explosive substances along the respective stages, the process of the present invention becomes a safe way of obtaining nanomaterial, thus allowing it to be implemented in areas wherein processes with hazardous substance aid are not allowed.Type: GrantFiled: October 18, 2011Date of Patent: May 3, 2016Assignee: INNOVNANO—MATERIAIS AVANCADOS, S.A.Inventors: Sílvio Manuel Pratas Da Silva, João Manuel Calado Da Silva
