Abstract
Use of solar energy for the production of synthesis gas from carbonaceous material. An aqueous dispersion of carbonaceous material is injected into a reactor in the form of a shower or a jet of droplets, and the droplets are allowed to sink inside the reactor across a high-temperature focal zone projected into the reactor by means of a system for the concentration of solar radiation. The residence time inside the reactor is adjustable by means of a countercurrent gas flow or by the injection of two or more discrete droplet jets in an impinging jet arrangement.
Claims14
A gasification process for the production of synthesis gas using solar energy, comprising:
- providing a solar gasifier reactor capable of admitting concentrated solar radiation and having top and bottom regions;
- directing concentrated solar radiation into said gasifying reactor to form a focal zone which produces a temperature sufficient for gasification therein;
- continuously injecting into said gasifying reactor an aqueous dispersion holding particulate carbonaceous material enclosed within water droplets so that the droplets pass through said focal zone for a time sufficient for the formation of synthesis gas;
- and
- withdrawing product synthesis gas from the reactor.
