This paper discusses the elaboration of adsorbents from oil *** experimental designs a response surface methodology(RSM),which has been applied to optimize the significant preparation factors,such as tempera-ture,time,and the activating agent *** results obtained from central composite design(CCD)revealed that the interaction between the factors was significant for the maximum quantity of adsorption(response).Planned results have shown that a maximum quantity of adsorption for methylene blue is 65 mg/g,which could be achieved with a temperature of 275℃over 2 h and a percentage of the activating agent of 45%.The predicted values agreed with the experimental finding,with a determination coefficient(R2)of *** model has been validated by experi-ments after conditions *** new material(RHO)was characterized by cation exchange capacity,zero charge pH,surface functions,X-ray fluorescence,specific surface area,and electron microscopy *** adsorption was determined using Langmuir,Freundlich and Temkin,which were used to describe the adsorption *** adsorption capacity of the material was about 263 mg/g,and the kinetic studies showed rapid adsorption.

One-pot chemical activation and pyrolysis process was developed for biochar production from red macroalgae residue of Gelidium *** macroalgae residue was activated by various catalysts(KOH,NaOH,H_(3)PO_(4),and CH_(4)ON_(2))with the two concentrations(2.5 wt%and 5 wt%)using a pulverization system followed by slow pyrolysis at 500℃.The activated biochars showed a porous morphology with an increase of water holding capacity compared to the unactivated *** properties of activated biochar observed by further characterization(i.e.,FTIR,SEM,TGA)revealed their feasibility to be used as an *** results of adsorption experiment confirmed that adsorption was dependent not only on the surface area but also on the surface charge,and functional *** sorption performance of activated biochars(AcBC),in terms of the adsorption of methylene blue,was comparable to commercial activated charcoal(Norit^(■)).NaOH(2.5 wt%)-activated biochar had the removal efficiency of 87%versus 97%for commercial activated charcoal.

Investigation of Organic Matter Extraction from Moroccan Oil Shale

This study focuses on investigating the effect of various solvents on the supercritical extraction of organic matter from Moroccan oil shales, with the goal of determining the optimal operating conditions that result in a high yield of high-quality oil rich in aromatic compounds. The results of this study demonstrate that the extraction yield and quality of the extracted oil heavily depend on the chosen operating conditions for supercritical or subcritical extraction of organic matter from oil shale. Additionally, the study found that phenol can effectively degrade oil shale and enable extraction of nearly all the organic matter, even under mild conditions (T = 390˚C, P = 1.2 MPa, Time = 2.5 h. Furthermore, the oils obtained through this extraction process are of high quality, with a rich content of maltenes, and a higher concentration of aromatic compounds and lower levels of sulfur than those obtained using other solvents.
