Metal casting company produces machinery spare part for manufactures. One of the product produced is dust filter. Most of palm oil mill used this product. Since it is used in most of palm oil mill, company often have problems to address this product. One of problem is the disordered of production process. It carried out by the job sequencing. The important job that should be solved first, least...

The objective of the project is to examine the potential use of wool as an industrial and/or laboratory adsorbent. This will be carried out by examining the metal sorption and desorption behaviour of a series of wool powders using radiotracer probes. Wool powders will be prepared using various milling techniques, and their metal-binding properties investigated using radiotracers such as Co, Cu ...

Present review paper deals with extensive literature survey in exploring the potential of microbial biomass for the sequestering of toxic heavy metals from aquatic streams. Presently more than half billion people are underprivileged and deprived of fresh water, clean air, soil and pure food. Contamination of aquatic streams due to release of toxic metal ions is a stern issue demanding global co...

This research was conducted for the purpose of studying the effect of CaF2 content in the composition of hot metal pretreatment flux, based on lime. It was followed in regards to the importance of fluorine amount decrease in hot metal pretreatment and steel making processes. For this purpose, lime based fluxes including 40, 30, 20 and 10 percent calcium fluoride were prepared and hot metal pret...

During the refining process of Incoloy825 nickel-based alloy, reaction between slag and Al Ti in alloy can result oxidation loss. Therefore, effect TiO2 Al2O3 contents (CaO–SiO2–Al2O3–MgO–CaF2–TiO2) on final was investigated by slag-metal experiment a 1-kg MoSi2 resistance furnace. The thermodynamic model established based ion molecular coexistence theory kinetic two-film theory. experimental r...

Supported metal catalysts, in particular noble metals supported on zeolites and oxides, are widely applied in large-scale processes, such as petroleum refining, petrochemical conversion, and automobile exhaust conversion. A crucial challenge in studying these catalysts lies in their complex nature, including non-uniform supports, variable sizes, shapes, and distributions of metal species and mu...
