Systems and processes for cellulosic ethanol production

1. An integrated process to produce fuel ethanol and biodiesel from cellulose comprising:

providing a raw cellulose stream to one or more containers selected from the group consisting of a vat, a bioreactor, and a tank by mixing a waste cellulose stream and an algae cellulose stream;

hydrolyzing the raw cellulose stream to form a hydrolyzed cellulose stream by reacting the raw cellulose stream with one or more fungi from the phylum Neocallimastigomycota;

liquefying the hydrolyzed cellulose stream to form a sugars stream;

separating the sugars stream to form a xylitol stream and a separated sugars stream;

fermenting the separated sugars stream to form a raw ethanol stream by reacting the separated sugars stream with a yeast feed in at least one fermenter;

separating the raw ethanol stream to form a fuel ethanol stream;

producing an algae stream by reacting the xylitol stream with algae in at least one algae bioreactor; and

reacting the algae stream in at least one biodiesel reactor to produce the algae cellulose stream and a biodiesel stream; and

recovering the fuel ethanol and the biodiesel from their respective streams.

2. The process of claim 1 , wherein reacting the raw cellulose stream with one or more fungi further comprises forming a hydrolysis carbon dioxide CO 2 stream and an ethanol stream.

3. The process of claim 1 , wherein liquefying the hydrolyzed cellulose stream further comprises heating the hydrolyzed cellulose stream and mixing the hydrolyzed cellulose stream with one or more enzymes.

4. The process of claim 1 , wherein liquefying the hydrolyzed cellulose stream further comprises heating the hydrolyzed cellulose stream and mixing the hydrolyzed cellulose stream with one or more bacteria.

5. The process of claim 2 , wherein fermenting the separated sugars stream by reacting the separated sugars stream with a yeast feed produces a fermentation CO 2 stream.

6. The process of claim 5 , wherein producing the algae stream further comprises reacting the hydrolysis CO 2 stream, the fermentation CO 2 stream, and an atmospheric CO 2 stream with the xylitol stream in the at least one algae bioreactor.

7. The process of claim 1 , wherein separating the raw ethanol stream includes using at least one molecular sieve.

8. The process of claim 1 , wherein separating the sugars stream further comprises chromatographically separating xylitol from the sugars stream to produce the xylitol stream and the separated sugars stream.
