This study accomplished a comparison between microfiltration and addition of coagulating agents to clarify sugar cane juice. Microfiltration tests were carried out using ceramic tubular membranes made with TiO2/a-Al2O3, with pore diameter of 0.2; 0.4 and 0.6 mm. The transmembrane…

Pellets made from sugarcane bagasse and molasses in weight proportions 1.0:0.5 and 1.0:1.0 (wt%) were water-steam activated during 1, 2 and 4h, at 850°C, by two processes, namely, (1) pyrolysis and activation in two different assays or (2) pyrolysis and…

This study aimed to analyze the convective drying in fixed bed of yellow passion fruit bagasse. Firstly, the initial moisture of the bagasse was determined in stove, at 105 ± 3ºC for 24 hours.  In the drying tests, it was…

Concern over exposure to endocrine disruptors (EDs) and impacts on wildlife and human has gradually increased in importance in recent years. Wastewater systematically receives most if not all of these chemicals, so a deeper understanding of the fate of EDs…

, This work reports the production of fatty acid ethyl esters (FAEE) from the transesterification of soybean oil in supercritical ethanol in a continuous catalyst-free process using different reactor configurations. Experiments were performed in a tubular reactor in one-step reaction…

, This paper evaluated the adsorption capacity of zinc by Bofe bentonite clay. Bofe clay was subjected to a thermal treatment for optimizing its adsorption capacity. The kinetic equilibrium of the process was studied in a finite bath system and…

, The work aimed to investigate the extraction of Mucuna deeringiana seed oil using supercritical carbon dioxide as solvent, and the chemical profile of fatty acid components. The experiments were performed in a laboratory scale unit in a temperature range…

Olive oil represents an important component of a healthy and balanced dietary. Due to commercial features, characterization of pure olive oil and commercial mixtures represents an important challenge. Reported techniques can successfully quantify components in concentrations lower than 1%, but…

The requirements of high production allied with product quality, process safety and environmental regulation, lead control systems to play a key role in the operation of chemical and biochemical plants. In petrochemical plants, furnaces are essential equipments for process operation…
