Abstract

The invention belongs to the technical field of hydrate preparation, and in particular, relates to a natural gas hydrate continuous reaction device with synergistic effect of adsorption and hydration.A main body structure comprises a first gas tank, a feeding pipe, a screw pump adsorption kettle, a solid-liquid mixing tank, a water tank, a first-stage reaction kettle, a second-stage reaction kettle, a liquid collecting tank, a hydrate collecting tank and a second gas tank; based on rich specific surface area and porous characteristics of activated carbon, natural gas is adsorbed by an adsorption axe of a screw pump, activated carbon with the porous characteristic is used as a carrier, the gas-liquid contact area is increased, nucleation and power generation of the natural gas hydrate areaccelerated, two-stage reaction is conducted through the first-stage reaction kettle and the second-stage reaction kettle layer by layer, the conversion rate of the natural gas hydrate is increased layer by layer, and efficient, rapid and continuous reaction of the natural gas hydrate is achieved. The device is simple in structure, natural gas is pre-adsorbed through activated carbon, and the gasstorage capacity is increased through the double mechanisms of physical adsorption and natural gas hydrate.

Description

Technical field: [0001] The invention belongs to the technical field of hydrate preparation, and specifically relates to a natural gas hydrate continuous reaction device with synergistic effects of adsorption and hydration, which realizes efficient and continuous reaction of natural gas hydrates, and greatly increases gas storage capacity by utilizing the synergistic effects of adsorption and hydration. Background technique: [0002] With the depletion of conventional fossil energy reserves such as oil and coal, people have begun to seek new energy sources on a large scale. Twice the total organic carbon content, it is regarded as an unconventional alternative energy source in the future, and has received widespread attention from all over the world. In addition, natural gas hydrate has higher gas storage capacity and milder storage conditions, which makes it have high application prospects in the field of natural gas storage and transportation. Compared with gas storage tec...
