Abstract

The invention discloses a biomass supercritical water gasification hydrogen production system and method thermally driven by focusing solar energy; wherein the system mainly comprises a concentrating system composed of a spinning-pitching tread heliostat and a conical surface solar secondary condenser, a solar cavity absorption reactor internally provided with a coiler flow reactor, a biomass and water transmission system, a product collection and analysis system and a systemic parameter acquisition system. Biomass and supercritical water absorb and focus solar radiation and carry out gasification hydrogen production reaction in the coil flow reactor. Compared with the plate type coupling hydrogen production system, the invention has the characteristics of simplified system, low cost, strong stability and favoured industrial amplification. The solar hydrogen production method provided by the invention utilizes solar heat supply to transform low-class biomass into high quality hydrogen energy through supercritical water gasification hydrogen production, the whole process is environmental-friendly without pollution, and renewable energy source is fully utilized, thus being beneficial to large-scale promotion and application of solar hydrogen production.

Description

technical field [0001] The invention belongs to the field of solar energy utilization technology and the clean transformation and utilization of biomass and organic waste, and in particular relates to a biomass supercritical water gasification hydrogen production system and method driven by focused solar heat. Background technique [0002] Today's fossil energy supply situation is increasingly serious, and the use of fossil energy forces the ecological environment to continue to deteriorate. The development and utilization of renewable energy has become the only way for my country to achieve sustainable energy development. Solar energy resources are clean, pollution-free and have huge reserves, but they are characterized by dispersion, instability and discontinuity. Converting solar energy into chemical energy can solve the problems of solar energy storage, transportation, and time and space constraints. [0003] As a clean energy, hydrogen energy is considered to be the mo...
