Abstract
Methods for fractional catalytic pyrolysis which allow for conversion of biomass into a slate of desired products without the need for post-pyrolysis separation are described. The methods involve use of a fluid catalytic bed which is maintained at a suitable pyrolysis temperature. Biomass is added to the catalytic bed, preferably while entrained in a non-reactive gas such as nitrogen, causing the biomass to become pyrolyzed and forming the desired products in vapor and gas forms, allowing the desired products to be easily separated.
Claims17
A process for producing pyrolysis oil comprising the steps of:
- providing a reactor containing multiple catalysts;
- fluidizing the catalysts;
- entraining a biomass fluidized catalysts, so that the biomass is pyrolyzed;
- and
- collecting the resultant pyrolysis oil.
A process for producing fuel comprising the steps of
- providing a reactor containing multiple catalysts;
- fluidizing the catalysts;
- entraining a biomass fluidized catalysts, so that the biomass is pyrolyzed to produce pyrolysis oil;
- and
- cracking the pyrolysis oil.
A process for producing fuel comprising the steps of
- producing pyrolysis oil;
- blending the pyrolysis oil with gas oil to produce an oil blend;
- and
- cracking the oil blend.
