Solid acid catalyst was produced from olive pomace (OP), characterized and used for the esterification of OP oil. pyrolyzed, physical activated by steam sulfonated using sulfuric acid. Commercial, coconut husk-based, carbon (CHAC) also comparison. The activation has shown a significant increase in (OPAC) surface area developing simultaneously its micro meso-porosity. sulfonation further increas...

in this study, microwave-assisted solvent extraction (mase) was used to recover oil residues from pomace olive using acidic hexane. results obtained demonstrated that oil extraction yield increased with time, the amount of acetic acid in hexane and power radiation. for both radiation powers used (170 and 510w), the optimal extraction time and most interesting content of acetic acid in hexane ar...

Olive, as a fruit, cannot be consumed directly due to the oleuropein substance it contains and needs to be processed into either table olives or olive oil through various production systems. Th e process of olive oil extraction results in olive oil as the main product, and two by-products, with olive pomace being one and brown-coloured Olive Mill Wastewater (OMWW) as the other. OMWW has no dire...

Different mixtures of olive pomace (OP), olive mill wastewater (OMWW) and olive pruning residues (OPR) were aerobically co-composted under natural conditions. Compost temperature showed a sharp increase in the first 40 60 days, followed by a stabilization at 60°C and a decline after 150 days, whereas compost water content ranged from 50% 55% to 25% 30%. Total and selective microbial counts were...

• A detailed description of ash-limestone interactions involving ash from biomass coal. mechanistic infiltration is provided. Comparative quicklime microstructure electrically heated calcination. Quicklime coarsening and reduced Ca-levels for both tested ashes. salt melt was suggested to cause the with olive pomace ash. Net CO 2 emissions production can be by introducing renewable solid fuels o...

Two mathematical methods to quantify adulterations of extra virgin olive oil (EVOO) with refined olive oil (ROO), refined olive-pomace oil (ROPO), sunflower (SO) or corn (CO) oils have been described here. These methods are linear and non linear models based on chaotic parameters (CPs, Lyapunov exponent, autocorrelation coefficients and two fractal dimensions) which were calculated from UV-vis ...

Abstract Olive pomace (OP) and olive oil (OPO) are low-cost, non-edible, by-products of processing. Converting OPO into biodiesel by (trans-)esterification a heterogeneous acid catalyst sulfonation with sulfuric could promote waste-to-energy actions. has high fatty content 126.39 mgKOH/goil, which does not allow the use base for production. Homogeneous such as be used, however wastewater should...
