Sulfonation of phenols extracted from the pyrolysis oil of oil palm shells for enhanced oil recovery.
The cost of chemicals prohibits many technically feasible enhanced oil recovery methods to be applied in oil fields. It is shown that by-products from oil palm processing can be a source of valuable chemicals. Analysis of the pyrolysis oil from oil palm shells, a by-product of the palm oil industry, reveals a complex mixture of mainly phenolic compounds, carboxylic acids, and aldehydes. The phe...
متن کاملControl of the rate of evaporation in protein crystallization by the ‘microbatch under oil’ method
Microbatch crystallization under oil is a powerful procedure for obtaining protein crystals. Using this method, aqueous protein solutions are dispensed under liquid oil, and water evaporates through the layer of oil, with a concomitant increase in the concentrations of both protein and precipitant until the nucleation point is reached. A technique is presented for regulating the rate of water e...
متن کاملStudy on potential environmental adsorption of egg shells to removal of lead and cadmium from Oryza sativa rice
Background: Removal of heavy metal ions from contaminated systems by agricultural and fruit and vegetable processing waste materials is an innovative and auspicious technology .The current study was designed for utilization of bio-adsorption white hard eggshell, as less expensive and much frequently available food waste materials, due to prospective metal bio-sorption capacity to toxic heavy me...
متن کاملEvaporation rate of water in hydrophobic confinement.
The drying of hydrophobic cavities is believed to play an important role in biophysical phenomena such as the folding of globular proteins, the opening and closing of ligand-gated ion channels, and ligand binding to hydrophobic pockets. We use forward flux sampling, a molecular simulation technique, to compute the rate of capillary evaporation of water confined between two hydrophobic surfaces ...
متن کاملRate control in dual source evaporation
Two-component thin films are deposited in a high-vacuum system from two close sources, heated by an electron beam which is deflected between them. By using quartz-crystal monitors the evaporation rates are measured separately, which is usually considered to be problematical. One rate signal is used to regulate the appropriate deposition rate by controlling the emission current. The other deposi...
