Abstract
A biomass gasification method and apparatus for production of syngas with arich hydrogen content. In the gasification process the gasification energy is supplied by the sensible heat carried by a high temperature agent combined with the heat released by the chemical reaction between calicined lime and carbon dioxide.
Claims15
A method for gasifying a solid material, comprising:
- a) providing at least one high heat source to supply energy for gasification in a gasifier containing the solid material, resulting in gases including CO2 and hydrogen gas, and particulates, the heat source provided by a method selected from the group consisting of:
- i) feeding a high temperature gasifying agent to supply heat into the gasifier;
- and/or
- ii) utilizing a Ca-based CO2 absorbent to supply exothermic reaction heat;
- b) separating syngas from the particulates in a separator;
- and
- c) recovering the Ca-based CO, absorbent by a heating step,
- wherein the gasifier is at atmospheric pressure, and wherein complete gasification is increased in the gasifier.
5 more elements
A gasification apparatus comprising:
- a) a high temperature gasifying agent generator, b) a gasifier, c) a solid gas separator, and d) a combustor for regeneration of sorbent.
