The strucutre of regenerated cellulose films can be controlled by the regeneration.Hofmeister sequence is applicable to describe the cellulose regeneration.The TOF of the most powerful gold/cellulose catalyst reached 604.79h1.The catalytic efficiency were in correlation with the pore size of the matrix.
The catalytic performances of gold nanoparticles immobilized on regenerated cellulose films were influenced by cellulose structure. Cellulose was regenerated in aqueous coagulants containing different electrolytes, to fabricate regenerated films with different coagulated network structure and property. Hofmeister sequence can be used to describe regeneration, namely more kosmotropic ions in the coagulants led to cellulose films with more homogeneous coagulated network structure, possibly due to the dehydration of cellulose caused by the ions. Gold nanoparticles were then immobilized on the films to prepare portable catalysts. The catalytic performance was influenced by cellulose structure. A linear relationship between the turnover frequency and the mesh size of cellulose films was observed. The results revealed that the catalytic performance can be controlled by cellulose structure, via altering the regeneration. This work provided not only the fundamental information about the intermolecular interactions between ions and macromolecules, but also an effective approach to construct powerful catalysts.
Potable Wash Plants, also known as Portable Gold Wash Plants, Portable Diamond Wash Plants, Small Gold Wash Plant, Portable Gold Mining Equipment, Portable Gold Mining Wash Plants, Small Gold Mining Equipment, or Portable Gold Trommel Wash Plants
The EXPLORERPortable Processing Plants are Portable Wash Plants exclusively designed, patented and developed by DOVE, for surface mining in exploration, pilot and small scale mining operations of alluvial Gold, alluvial Diamond, Gemstones, base metals metals and ferrous metals.
EXPLORERPortable Plants are configured and customized with multy-stage classifier and concentrators according to the ore specification as a fully integrated processing plant for 100% recovery of gold, diamonds, base metals, ferrous metals, with no loss.
EXPLORER Portable Plants are easily assembled, disassembled, installed and transported through the mining site, resulting in rapid deployment on the site. Plants are fully portable to allow ease of movement in the field.
EXPLORER Portable Plants offer features such as the ability to easily be operated and maintained on the site, and dont require much human interference during the processing of the minerals, offering a user-friendly experience for the operator.
EXPLORER Portable Plants can be tailor made according to the mine specifications and customized to be integrated with various portable equipment in order to form a complete production line for the full recovery of minerals.
EXPLORER Alluvial Gold Processing Plants are configured with our special Multi-Stage Classification Trommels, which enables the plant to achieve up to three (3) sizes classification simultaneously as well as resolving the Heavy Clay content concern, Duplex Jig Concentrators and DOVE Centrifugal Gold Concentrators, which will ensure that the processing of the ore will capture both gold nuggets and fine gold with no loss, down to 40 microns (0.040mm), with 100% recovery.
EXPLORER Alluvial Diamond Processing Plants are configured with our Trommels Classifier Screens/Scrubber Screens, which enables the plant to thoroughly wash the ore and break the host clay if necessary, Duplex Primary and Secondary Jig Concentrators, and Scavenger Jig Modules for the simultaneous processing, concentration and separation of coarse and fine diamonds, with 100% recovery.
