Controlled release of foam from mesoporous silica-surfactant nanocomposite for enhanced natural gas production

Controlled Release of Amphoteric Surfactant from Mesoporous Nanosilica To Enhance Natural Gas Production at High Temperatures

“…The best integrity of the nanosilica block was achieved by the acid catalyst process (A). In comparison, samples made by the other three routes with two-step or base catalysts were smaller or dismantled within 24–48 h. This behavior differs from our previous studies with cetyltrimethylammonium quaternary surfactant …”

“…In comparison, samples made by the other three routes with two-step or base catalysts were smaller or dismantled within 24−48 h. This behavior differs from our previous studies with cetyltrimethylammonium quaternary surfactant. 24 Hence, nanosilica synthesized via the sol−gel process using the acid as catalyst was selected as the best procedure for the encapsulation of CAB.…”

“…Studies have shown that the released rates increased at higher temperatures . In our previous study, the controlled release of the cationic surfactant with nano silica was investigated . However, the controlled release of environmentally friendly amphoteric surfactants for the foam generation from mesoporous silica as agglomerated solid sticks to enhance gas production has not been studied.…”
