Abstract
Multiple catalytic processing stations couple with a system which produces volatile gas streams from biomass decomposition at discrete increasing temperatures. These catalytic processing stations can be programmed to maximize conversion of biomass to useful renewable fuel components based on input feedstock and desired outputs.
Claims28
A system for the conversion of biomass to renewable fuel, comprising:
- a programmable number of processing stations (N) for subjecting biomass to at least one programmable starting temperature (Tstart) and for incrementing the temperature by programmable increments (ΔT) to produce a volatile and a non-volatile component;
- a series of catalyst columns;
- means for subjecting the volatile components generated in each station through the series of catalyst columns to produce at least one renewable fuel;
- a hydrotreating catalyst;
- and
- means for subjecting at least one renewable fuel to the hydrotreating catalyst to produce at least one hydrotreated renewable fuel.
