BEI Dilute-Acid Cellulose Hydrolysis Process & Reactor System (BEI-CH&P&RS) ; is technically feasible and economically profitable by-way-of a new, modern BEI Small Scale Cellulose to Fuel Ethanol Production Plant.   

BEI CH&RS processing at moderate chemical reaction temperatures and for low-cost cellulosic feedstocks solids in a dilute-acid slurry of moderate density provides the following unforeseen breakthrough results:

1. Dilute-Acid requirement:  down 34% to 66% of Known-Art,
2. Process Heat requirement:  down 30% to 70% of Known-Art,
3. Alpha-Cellulose Hydrolysis conversion to glucose:  up 10% to 70% is 130% of Known-Art,
4. The HCH and ACH solutions combination into a single liquid product.

The benefits provided by the BEI CHP & RS include the following;

1. Processing cost reductions based on double use of the acid, the energy and water.
2. Total capital costs, and total production operating costs are reduced to about 70%.
3. USDOC NIST-OERI recommended BEI CHP&RS to USDOE for Federal Funding.
4. USDOE-EERE I&IP financed The BEI Refined-Engineering Proto-Type Pilot Plant Project; for design; construction and operation for the BEI CHP&RS Process Validation at pilot plant scale; which involved the Dilute-Acid Cellulose Hydrolysis (DACH) of:  (a) Pine Softwood Sawdust Cellulose, and (b) Corn DDGS & CGF Fiber Cellulose.
5. Brelsford Engineering, Inc. holds the U.S.  and Canadian Patents; which covers the BEI Dilute-Acid Cellulose Hydrolysis Process and Reactor System (BEI CHP&RS).

In the US DOE-EERE-I&IP Project, the BEI low-cost dilute-acid cellulose hydrolysis process reaction conditions for the three indicated low-cost feedsotcks (soft wood, corn fiber, MSW paper), are included in the following: 

1. Dilute Sulfuric-Acid @ 1.0%, 1.75% and 2.5%,
2. Liquid to Solids Ratio of 12:1, 10:1 and 8:1,
3. Reaction Temperatures of 140C and 150C for Hemi-Cellulose Hydrolysis (HCH); and 170C, 180C and 190C for Alpha-Cellulose Hydrolysis (ACH).  The BEI Pilot Plant Process Validations of the BEI CHP&RS; are BEI reported.

Brelsford Engineering, Inc. (BEI) has available for private and confidential sale an improved industrial design of the new U.S. and Canada patented BEI-DACH-P&RS, along with specifications for related process equipment, instruments and control systems.
