Abstract
Processes for producing high biogenic concentration Fischer-Tropsch liquids derived from the organic fraction of municipal solid wastes (MSW) feedstock that contains a relatively high concentration of biogenic carbon (derived from plants) and a relatively low concentration of non-biogenic carbon (derived from fossil sources) wherein the biogenic content of the Fischer-Tropsch liquids is the same as the biogenic content of the feedstock.
Claims9
A process for producing biogenic carbon content fuel products derived from organic materials that are produced from plant derived carbon (biogenic) as well as non-biogenic derived carbon (fossil based) materials and other non-carbonaceous materials, the process comprising:
- a) receiving processed organic material feedstock, the processed feedstock having been processed to produce a feedstock that contains a higher concentration of biogenic carbon than non-biogenic carbon;
- b) gasifying the processed organic material feedstock to produce syngas having a higher concentration of biogenic carbon than non-biogenic carbon in the syngas;
- c) conditioning the syngas, where in the conditioning step comprises:
- i) removing contaminants from the syngas;
- and
- ii) adjusting the H2:CO2 ratio in the syngas to a predetermined value;
- d) converting the syngas into Fischer-Tropsch liquids having a higher concentration of biogenic carbon than non-biogenic carbon;
- and
- upgrading the Fischer-Tropsch liquids into fuel products.
