CELLULOSE ETHANOL REFINING

Availability and affordability of energy limit economic viability and growth of all nations world wide. Shrinking fossil oil reserves (Peak Oil) and monopolistic tight marketing controls on automotive fuels and petrochemical product markets put unjustifiable economic strains on public consumption, while all along, through greenhouse gas emissions (C02, NOx
etc.), drastically endangering human habitability of the earth's environment.

It is generally known (and accepted) that a major fraction of all nations' balance of trade earnings is invested in petroleum product purchases (foreign oil dependence) and forms a cap on social development for all countries world wide. Induced by long-term effects, associated by fossil fuel burning, global destruction is now mitigated by government regulated renewable fuel standards which encourage conversion of renewable grain (starch) and lignocellulose sources into transportation fuels, such as ethanol and biodiesel.

Competition of grain-derived ethanol with food now directs attention to the potentially more profitable but more complex lignocellulosics as sources for fermentable sugars and means for competitive control of fuel prices and supplies in the future.

Lignocellulosic materials in the form of trees and agricultural crop residues (straws, cornstover, grasses, bagasse etc.) are widely distributed on the earth. Their yields can be multiplied on purposeful cultivation now for production of renewable, clean, greenhouse gas-neutral energy sources. Fuel product (cellulose ethanol) and value maximization are possible from biomass and require isolation and conversion by refining each lignocellulose chemical component (carbohydrates, lignin and extractives).

The ACOS process excels by its ability to dissolve all biomass forms to their three major chemical components and refine the cellulose (glucose and mannose) to a low cost cellulose ethanol and an endless range of chemical co-products.

 

THE ACOS TECHNOLOGY

  1. Unique and Proprietary

  • The process consists of a patented, super-dilute (<0.05 %) acid catalyzed,  total, single step simultaneous  hydrolysis of both carbohydrates and
    lignin/extractives in a congruous low boiling organic solvent solution.
  • Solvent recovery/recycling separates the carbohydrates and lignin/extractives platforms for direct refining into cellulose ethanol and other value added chemicals, food, pharmaceutical and cosmetic products.

2.0 Efficient

acos-4

The Original Organocell® Pulp Mill (450T/day capacity) at Kellheim (Germany); A fascimile facility for the Acos prosess (Completed in December 1992)

  • The ACOS process hydrolyzes random sized un-pretreated green biomass particles into sugars and lignin in a continuous, counter-current pulping reactor in less than 60 minutes and as little as 5 minutes depending on the reaction temperature used. Biomass dissolution and chemical recovery rates
    exceed 98.5 %.
  • Solvent recovery by flashing and distillation not only separates the carbohydrates from the lignin/extractives fractions but automatically concentrates the dissolved components four times, yielding solutions with greater than 36 % sugar solids content.
  • The ethanol concentration exceeds 12 % in the beer on fermenting the sugars with a flocculating yeast.
  • The ACOS process operates on a closed water cycle and is water self-sufficient on processing green (> 50 % moisture content) feedstocks.
  • The process recovers 99.95 % of the solvent and is solvent self-sufficient.
  • The ACOS process operates without wastes and pollution.

3.0 Versatile

  • The ACOS process converts all lignocellulose materials: coniferous, deciduous and agricultural residues with equal efficiency.
  • Mixed feedstock processing is normal .
  • Ethanol recovery is 380 L/T (100 gallons/T) from coniferous woods, 350 L/T (92.5 gallons/T) from deciduous woods and straws and 280 - 310 L/T (74 to 82 gallons/T) from cornstover and bagasse, respectively.

 4.0 High Value Recovery

  • The return on invested capital (ROI) is between 5 to >100 % depending on plant capacity and feedstock type.
  • Highest value recovery is obtained from coniferous feedstocks.
  • The ethanol value is about 10 % of the total value recovered from the co-products ranging from xylitol, vanillin, lignin and slow release fertilizer.
  • The high value recovery facilitates:
    a. operation at small economies of scale: 50 - 500 T/day feedstock capacity.
    b. Production of credit-rated cellulose ethanol which is competitive with gasoline at less than US $20/bbl oil price.

Summary of the ACOS Technology Benefits

  • The ACOS process can produce ethanol from biomass at small economies of scale and thereby, is suitable for regionally distributed ethanol production to reduce feedstock and fuel product transportation costs.
  • ACOS processing economics does not depend on the ethanol value.
  • The ACOS process refines biomass to value-added co-products to maximize the chemical value recovery and minimizes the production cost of ethanol.
  • ACOS ethanol can be produced totally (>96%) carbon neutral in energy self-sufficient refineries.
  • The ACOS process is the cleanest, least energy demanding and most efficient wood hydrolysis technology currently competing world wide.
  • The process is an efficient job creator in both raw material procurement and refinery operating processes.

EXECUTIVE PROJECT SUMMARY

Government mandates are now driving development and implementation of renewable energy technologies particularly, second generation (cellulose) ethanol production.
Economical and competitive production of bioethanol depends on total fractionation and high value generation from each biomass component.
The ACOS biorefining technology is the only means for total (98.5 % minimum) dissolution of biomass in a single step to its molecular components (carbohydrates, lignin and extractives) in forms directly suitable for further refining to ethanol, butanol and co-products at relatively small economies of scale, afforded by the high returns on investment (ROI).
Specifically, the first refinery of 350 T/day feedstock (45,220,000 L/yr or 12,000,000 gallons/yr ethanol) capacity is planned at Malakwa, British Columbia, Canada, where softwood feedstock for 15 years is contracted. A product off-take purchase order is issued by VIACHEM (Texas, USA).
Plant engineering and construction are expected to take 16-18 months. All refinery equipment is available from North American suppliers.
The Malakwa project will create 115 full time refinery plant positions and 35 in raw material procurement and transportation while construction will employ 350 workers and 20 engineers for one year. The refinery is designed with closed water and volatiles and without solid emissions according to the Maximum Available Control Technology (MACT) standards.

The ACOS process is considered commercial-ready. Several other projects in addition to Malakwa are at various stages of development. .PASZNER TECHNOLOGIES INC. (the technology developer and marketer) will participate in the ownerships of the refineries pursuing a wide variety of chemical options depending on the available feedstock at each location.
