Abstract
The present invention relates to methods for processing biomass to selectively yield a variety of hydrocarbon molecules and hydrogen as products, wherein some or all of these products can be further utilized for other biomass processing sub-processes, particularly wherein they lead to the generation of biofuels and/or other high-value products.
Claims6
A. method comprising the steps of:
- a) transesterifying a first portion of triglycerides to yield monoesters;
- b) steam-reforming a second portion of triglycerides to yield bio-derived H2;
- c) hydroprocessing at least a portion of the monoesters produced in. step (a) with H2 in a hydroprocessing reactor to yield one or more hydrocarbon products of a first type, wherein a portion of the H2 so utilized is provided by at least a portion of the bio-derived H2 produced in step (b);
- d) pyrolyzing non-triglyceride biomass to yield a pyrolysis oil;
- and
- e) hydroprocessing at least a portion of the pyrolysis oil in a hydroprocessing reactor with H2 to yield one or more hydrocarbon products of a second type, wherein at least a portion of the H2 utilized in the hydroprocessing is provided by at least a portion of the bio-derived H2 produced in step (b).
