Effects of pyrolysis conditions on the porous structure development of date pits activated carbon

Activated carbons were prepared from biomass of Algerian date pits for developing efficient and cheap adsorbents in the aim to remove heavy metals from waste water. Carbon adsorbents were obtained following two successive treatments: pyrolysis under dry nitrogen flow and physical activation under wet nitrogen flow. Pyrolysis process was optimized by varying some operating parameters […]

X-ray imaging for fungal necrotic spot detection in pistachio nuts

The potential of X-ray imaging for detecting pistachios with kernel necrotic (KN) spots was the main objective of this study. X-ray images of whole pistachios were compared with colour pictures of the same nuts taken after the kernel was opened by splitting it in two. The necrotic spots appear in the X-ray images as darker […]

The study of ultrasonic-assisted aqueous enzymatic extraction of oil from peanut by response surface method

Based on the optimum ultrasonic temperature and time parameters obtained from single-factor experiment; the response surface analysis method is employed to design and optimize the parameters in the experiment. The optimum parameters obtained from response surface analysis are as follows: enzyme additive amount 1.7%; hydrolysis time 3.8 h; hydrolysis temperature 56 °C; materials to water […]
