In the industrialization of hydrate technology, the most important problem is the efficiency of synthesis and capacity of hydrates. The hydrate strengthened synthesis technology was studied with the newly atomization synthesis system to solve the problem of storage and transport of natural gas hydrate. The research shows that the increase of pressure brings improvement for hydrate formation; atomization and additives composition provide the most optimistically gas-liquid transfer conditions, accelerates the process of dissolution, nucleation and crystal growth to a great extend. The reaction velocity is doubled, and the gas volume ratio is significantly improved. Both reformation in aqueous with hydrate dissociation and addition of crystal seeds can speed up nucleation process, shorten induction time, and greatly enhances the whole hydrate formation velocity as a result.
