The synthesis of NaY-zeolite was performed hydrothermally. preparation the bifunctional catalysts achieved by loading NH4Y-zeolite with a cheap Zr metal, as second tiny amounts Pt to compose Pt-Zr/Y-zeolite catalyst. Different characterization methods (i.e., XRD, SEM, EDX, BET, and AFM) were used investigate catalyst properties. catalytic performance studied performing hydroisomerization n-hept...

The basic unit operations in vegetable oil processing are shown in Figure 4. Oil is extracted from plant material (oilseeds) using a solvent, usually hexane. Published research indicates that about 50}70% of the hexane can be recovered and recycled using nanoRltration membranes instead of the evaporators used today, thus reducing energy consumption substantially. The extracted crude oil is most...

Background Fourier transform mid-infrared (FT–IR) microspectroscopy is a label-free optical method based on the interaction between an incident light beam and matter. This vibrational spectroscopy permits to probe the biochemical composition of the analyzed sample and thus gives information about the structure of this sample. Associated with an imaging system, FT–IR microspectroscopy of human t...

Deodorization of vegetable oils may introduce potentially carcinogenic, as well genotoxic contaminants, generating health risks for consumers. However, the deodorization step refining process leads to formation 3-monochloro-1,2-propanediol (3-MCPD). 3-MCPD has been classified carcinogenic humans by World Health Organization (WHO). The purpose this study was optimize recently updated oil treatme...
