Abstract

The invention provides an oil preparation and gas production system and technology by conducting pressurization, hydrogenation and pyrolysis on large-sized seaweeds. The system comprises a rapid thermal cracking system and a secondary pyrolysis system; the rapid thermal cracking system comprises a pressurization feeding system, a rapid thermal cracking system, a particle separation device, a filtration device, a hydrogen material flow pipeline, a flammable gas tank, an oil-gas separator and an oil storage tank, the secondary pyrolysis system comprises a secondary pyrolysis furnace, a secondary pyrolysis fuel bin and a dreg falling opening, and the second pyrolysis furnace comprises two feed inlets. The whole system is simple in structure, the oil yield of seaweed biomass is high, the problems of solid waste semicocke losses and environmental pollution are avoided, and efficient and clean utilization of the large-sized seaweed biomass resource is finally achieved.

Description

technical field [0001] The invention belongs to the technical field of utilization of large seaweed biomass resources, and relates to a pyrolysis oil production and gas production system and a production process for pressurized hydrogenation treatment of large seaweed biomass. Background technique [0002] With the dwindling reserves of traditional fossil energy (coal, oil, natural gas) and the environmental pollution caused by the use of fossil energy, which directly threatens the survival and development of human beings, it has become a priority for governments to attach importance to and develop renewable and environmentally friendly energy. According to consensus, the development of clean and renewable energy has become a global pressing issue in the 21st century. There is a rich "green" renewable energy source in nature, biomass energy, which accounts for 14% of the world's total energy consumption, second only to oil, coal and natural gas. However, in some cases, prod...
