The olive oil sector is one of the most widespread agricultural and agro-industrial activities in the Mediterranean region, and it also produces a significant amount of waste biomass. This research aimed to find energy valorisation for the olive oil by-products through biogas/biomethane production from olive pomace (OP) and olive mill wastewater (OW). To this end, these biomasses underwent preliminary treatments: the OP was processed using an ionic liquid (IL) consisting of triethylamine and sulfuric acid [Et3N][H...

Natural gas hydrate reservoirs often consist of a mixture of various gaseous species: small-chain hydrocarbons, as methane, ethane, propane and butane, and other species, as carbon dioxide, nitrogen, oxygen, hydrogen sulfide and others. Every species shows different forming conditions. Moreover, those conditions may change as a function of the mixture composition and the properties of the surrounding environment. The present study deals the production of hydrates with small-chain hydrocarbons, within a silica-base...

The most attractive option to recover methane trapped within natural gas hydrate reservoirs, consists of the so-called -replacement process-, mainly based on the contemporary injection of carbon dioxide during the mining process. If appropriately carried out, this process allows to improve the amount of methane recovered, preserve the crystalline hydrate cages and permanently store enough carbon dioxide to make this source definitively carbon neutral. For that reason, this process is widely studied worldwide. Howe...
