Crude oil; is a fossil fuel containing carbon, hydrogen, sulfur and many other components one of the world's largest most widely used energy sources. However, in order for crude oil to be as an source, it must refined. With use petroleum products obtained result refining, very high amounts SOx gas are released into atmosphere. These gases seriously harm both environment human health. This study...

In this research, the adsorption of gallium onto natural zeolite (clinoptilolite) and two mesoporous-activated carbons were compared evaluated. The clinoptilolite was treated with HCl (HCPL), while (MCSG60A MCO1) synthesized by replica method, using sucrose as carbon precursor silica gel template. These carbonaceous materials showed large pore sizes mesoporous surface, well a suitable surface c...

Synthetic exchanged zeolites have proved to be active catalysts for the selective catalytic reduction (SCR) NO x by hydrocarbons as reductors in the presence of O 2. The abundance and potentiality of argentine zeolite mineral resources encouraged us to analyze the possibitity of taking advantage of these minerals as starting materials for catalyts preparation. In this sense, clinoptilolite-rich...

The ex vivo effect of tribomechanically micronized zeolite (MZ) on the binding of 3H-8-OH-DPAT to 5-HT(1A) and 3H-5-HT to 5-HT(1B) receptors was investigated in the brain of nontumorous (control) and mammary carcinoma bearing female mice. During 14 and 28 days mice were fed with standard food, standard food supplemented with 25% of MZ, or standard food supplemented with 25% of non tribomechanic...

Single and multicomponent gas permeation tests were used to evaluate the performance of metal-supported clinoptilolite membranes. The efficiency of hydrogen separation from lower hydrocarbons (methane, ethane, and ethylene) was studied within the temperature and pressure ranges of 25-600 °C and 110-160 kPa, respectively. The hydrogen separation factor was found to reduce noticeably in the gas m...

The chemical behavior in an aqueous medium of a natural zeolitic material, NZ (mainly consisting in crystals of the zeolites clinoptilolite/heulandite) has been studied through electrochemical techniques, complemented by atomic absorption spectrometry. The time dependence of the conductivity of the aqueous medium in the presence of NZ, showed a steep increase at the beginning followed by a slow...
