Patent ID: 8535840

Claim:
A method of converting solid biomass into electricity, which comprises the following method steps: A1) introducing solid biomass into a gasifier; A2) introducing a gasification medium into the gasifier; B) introducing a product gas originating from the gasifier into a particle separator to produce a product gas with low particulate content; C) introducing the product gas with low particulate content emerging from the particle separator into a reactor for catalytic conversion; D) introducing the product gas with low particulate content into a sulfur absorber to produce product gas substantially freed of sulfur; E) introducing the product gas substantially freed of sulfur in the sulfur absorber into a fuel cell for generating electrical energy; F) executing method steps B and C in a single apparatus G) using a monolith inside a filter element for complete or partial catalytic conversion in the apparatus; H) using a by-pass control for adjusting the catalytic conversion in respect of the product gas with low particulate content; and the bypass control shifting the monolith within the filter element infinitely variable from a fully passive position into a fully active position, wherein the monolith is, in the fully passive position, completely bypassed by the product gas with low particular content, and the product gas with low particulate content is forced to entirely flow through the monolith when positioned in its fully active position.
