A modified shrinking core model for leaching of aluminum from sludge solid waste of drinking water treatment
" The kinetics of aluminum leaching from sludge solid waste (SSW) using hydrochloric acid at different leaching temperatures (30-90°C) was studied. A mathematical model was developed based on a shrinking core model by assuming first-order kinetics mechanisms for leaching and an equilibrium linear at the solid-liquid interface. The proposed model is suited to fit experimental data with three fitting parameters and to simulate the leaching of aluminum from SSW, which was validated with the mass transfer coefficient (kc, cm/s), diffusion coefficient (De, cm2/s), and reaction ...

Pemodelan Ekstraksi Asam Lemak dari Nannochloropsis sp. Menggunakan CO2 Superkritis dengan Model Inti Menyusut = Modeling of Fatty Acid Supercritical Carbondioxide Extraction from Nannochloropsis sp. Using Shrinking Core Model
" Penelitian ini bertujuan untuk mendapatkan model matematis yang valid untuk ekstraktor unggun diam untuk proses ekstraksi asam lemak dari mikroalga Nannochloropsis sp. dan mendapatkan parameter kinetika ekstraksi asam lemak dari Nannochloropsis sp. Ekstraksi senyawa asam lemak dilakukan menggunakan metode ekstraksi fluida superkritis (EFS) dengan fluida superkritis CO2. Dalam penelitian ini, proses EFS akan dipelajari dengan menggunakan model inti menyusut, dan perhitungan model terkait neraca massa proses ekstraksi dilakukan secara numeris metode implisit Crank-Nicolson dengan program ...
