1. Modelagem e simulação de reatores autoclave para produção de PEBD
The low density polyethylene (LDPE) is a thermoplastic resin manufactured by high pressure processes, with autoclave or tubular type reactors. The present scenario is of growing demand for LDPE produced at competitive costs, through high performance and capacity plants, so that the process and product development becomes a key factor for the producers, and p

2. Modeling and simulation of an industrial autoclave reactor for the production of low-density polyethylene (PEBD) / Modelagem e simulação de um reator autoclave para a produção de polietileno de baixa densidade (PEBD)
High-pressure polymerization in autoclave reactors is one of the most currently technologies used for production of polyolefins, particularly polyethylene. Pressures until 3000 atm and temperatures covering the range from 150 to 300 DEGREES C are usually employed in this system. In the present work high-pressure ethylene polymerization process to produce low

3. Oxidação umida catalitica da lignina em reatores trifasicos com produção de aldeidos aromaticos
The lignocellulosic material, representing the largest natural renewable resource, occurring in the plants under the cellulose form, hemicellulose, lignin and extractive, with the lignina corresponding about 30% of this total one. The routes of lignin chemical processing, with prominence for the oxidations processes, with the objective of vanilin production,

4. Liquefação direta de lixivia negra e de lignina da hidrolise acida de eucalipto em reatores batelada e continuo
Direct Iiquefaction of black Iiquor was studied from the puiping process of wood like eucaliptus, pinus elliiotti and taeda, and of Iignin obtained as subproduct in the acid hydrolysis of eucaliptus through the sodium formate/water/argon system. The reactions were realized under hydrogenolysis and acid hydrolysis conditions at temperature and pressures of 30
