The present disclosure provides a method for preparing hydrogen-rich gas by solid organics. For example, solid organic raw materials are heated in a pyrolysis reaction device to perform pyrolysis reaction, and gaseous product generated from the pyrolysis reaction performs gasification with steam in a moving bed gasification reaction device to generate hydrogen-rich product. The present disclosure also provides a system for preparing hydrogen-rich gas by solid organics, and the system may include a solid heat carrier grading-dedusting device; a pyrolysis reaction device; a moving bed gasification reaction device; and a riser and combustion reactor. The present disclosure may operate at atmospheric pressure, and the technology is simple and suitable for the gasification and co-gasification of various high-volatile solid organics, such as raw materials containing a relatively large amount of moisture, mineral substance, and sulfur content. 1. A method for preparing hydrogen-rich gas from solid organics , the method comprising:heating solid organic raw materials in a pyrolysis reaction device for pyrolytic formation of a gaseous product and steam; andperforming gasification of the gaseous product and steam in a moving bed gasification reaction device to generate hydrogen-rich gas, in which the gaseous product is generated from pyrolysis;wherein the pyrolysis reaction device is in parallel with the moving bed gasification reaction device, wherein, by passing through a solid heat carrier grading-dedusting device, the solid heat carrier is divided into two parts that are fed into the pyrolysis reaction device and moving bed gasification reaction device, respectively, wherein, when leaving the pyrolysis reaction device and moving bed gasification reaction device, the two parts of solid heat carrier are fed into a riser and combustion reactor to be heated and raised, and are then passed into the solid heat carrier grading-dedusting device to be further divided into two parts ...
