A. GENERAL
USES OF BIOMASS OILS AND FATS AS FUELS
VEGETABLE OILS, SUCH AS RAPESEED, SOYA, JATHROPA, PALM-OIL, ETC. AND ANIMAL FATS SUCH AS BEEF TALLOW, PORK LARD, ETC. ARE NATURALLY OCCURING TRIGLYCERIDES (FATTY ACID TRIESTERS OF GLYCEROL). THEY ARE A RENEWABLE SOURCE FOR ALTERNATIVE („GREEN”) FUELS IN DIESEL ENGINES.

TRIGLYCERIDE
MOLECULAR MASS: 950 – 1000
à HIGH VISCOSITY (35-50 cSt)
FOR FUEL PURPOSES TRIGLYCERIDES CAN BE UTILIZED IN A NUMBER OF WAYS:
1/ DIRECTLY (AFTER REFINING): STRAIGHT VEGETABLE OILS („SVO”)
- à NEED PREHEATING ON ACCOUNT OF THEIR HIGH MOLECULAR MASSES/HIGH VISCOSITIES, TO BE ATOMIZED PROPERLY INTO THE COMBUSTION CHAMBER
PROBLEM: REQUIRES MOTOR MODIFICATION
- „SVO” WITH „THINNERS” (MICROEMULSIONS)
PROBLEM: INSTABILITY DURING STORAGE
2/. GENETICALLY MODIFIED TRIGLYCERIDES WITH „SHORT” – CHAIN (C8 – C12) FATTY ACID MOIETIES WITH ENSUING LOWERED MOLECULAR MASSES/LOWER VISCOSITIES
PROBLEM: PUBLIC RESISTANCE/TIME FACTOR
3/. THROUGH FRAGMENTATION OF TRIGLYCERIDES INTO SMALLER MOLECULES (WITH LOWER MOLECULAR MASSES/LOWERED VISCOSITIES):
A/. VIA CATALYTICAL HYDROCRACKING (E.G.: „NExBTL” PROCESS) à YIELDS HYDROCARBONS („PARAFFINS”) + WATER + CARBONDIOXIDE
PROBLEM: HYDROGEN IS FOSSIL (METHANE) DERIVED, OXYGEN CONTENT OF TRIGLYCERIDES IS LOST (NO INTERNAL OXYGEN REMAINS TO ENHANCE COMBUSTION AND TO LOWER PARTICULATE MATTER IN EMISSIONS), THE RESULTING STRAIGHT-CHAIN PARAFFINS HAVE HIGH CLOUD/MELTING POINTS à THE PROCESS REQUIRES AN ADDITIONAL ISOMERIZATION STEP TO GET BRANCHED-CHAIN SPECIES à EXTREME REACTION CONDITIONS à HIGH INVESTMENT/OPERATING COSTS

B. „THE GLYCEROL SYNDROME”
WORLD-PROBLEM OF ALL BIODIESEL PRODUCERS IN 2007: HOW TO OVERCOME THE „GLYCEROL-SYNDROME”? :
THIS SIDE-PRODUCT HAS VERY UNFAVOURABLE PROPERTIES:
o CONTAMINATED WITH METHANOL, WATER, SALTS, COLOURANTS
o REQUIRES COSTLY REFINING
o GROSS OVERSUPPLY (OVER 500 000 TONS IN EUROPE ALONE)
o RAPIDLY ACCUMULATING/UNSALEABLE STOCKS
o ENVIRONMENTAL PROBLEMS ON ACCOUNT OF 60-70 LITERS SEWAGE/MT BD
SOME POSSIBLE OUTLETS:
A/ UTILIZING IT FOR MANUFACTURING ADDITIVES FOR BD (KETALS/ACETALS, TO LOWER POUR POINT AND CLOUD POINT)
PROBLEM: DECREASED HEAT OF COMBUSTION/LIMITED UPTAKE

- ENHANCED FORMATION OF ACROLEIN THROUGH H2O ELIMINATION à POLYMERISATION à CLOGGINGS/DEPOSITS IN MOTOR à FORMATION OF AROMATICS à LOWERING CETANE NO. + UNFAVOURABLE EMISSION PROFILE
C. OUR SOLUTION: „TBK” BIODIESEL!
A TOTALLY NEW CONCEPT AND APPROACH TO
- ELIMINATE AN ENVIRONMENTAL PROBLEM
- INCREASE BIOFUEL YIELDS OUT OF TRIGLYCERIDES BY 10%.
- INTRODUCE AN ECO-FRIENDLY, WASTELESS PROCESS
WE PERFORM PARTIAL TRANSESTERIFICATION (INTERESTERIFICATION) OF TRIGLYCERIDES WITH ALKYL ESTERS OF SHORT-CHAIN CARBOXYLIC ACIDS à CHEMICALLY MODIFIED TRIGLYCERIDES WITH REDUCED MOLECULAR MASSES à LOWERED VISCOSITIES, CLOUD POINTS AND POUR POINTS à NO GLYCEROL FORMATION, NO LOSS OF STARTING TRIGLYCERIDES, AS THEY ARE TOTALLY TRANSFORMED INTO ENERGY-YIELDING MATERIALS:

MODIFIED TRIGLYCERIDE FAME
MOLECULAR MASS: 450 – 650 (BIODIESEL)
NOVEL BIODIESEL = MODIFIED TRIGLYCERIDES AND/OR THEIR BLENDS WITH BIODIESEL/PETRODIESEL
TYPICALLY A „TBK-BIODIESEL” FUEL IS COMPOSED OF 60-70% MODIFIED TRIGLYCERIDES AND 30-40% OF METHYL/ETHYL ESTERS OF DISPLACED FATTY ACIDS
ADVANTAGES AND FAVOURABLE PROPERTIES OF THE NEW BIOFUEL:
- EACH AND EVERY ATOM OF BIOMASS TRIGLYCERIDE IS UTILIZED FOR FUEL PURPOSES
- 30% MORE INTERNAL OXYGEN CONTENT à BETTER COMBUSTION, LESS SMOKE/SOOT
- UNIVERSAL PROCESS FOR ALL KINDS OF VEGETABLE OILS/ANIMAL FATS
- GLYCERYL MOIETY IS RETAINED à EXTRA YIELD OF BIOFUEL FROM BIOMATTER
- INCORPORATED CARBOXYLIC ESTERS à AT LEAST 10% EXTRA YIELD OF BIOFUEL
- AT LEAST 10% MORE PRODUCT à AT LEAST 10% MORE PROFITS
- AT LEAST 10% LESS ARABLE LAND NEEDED FOR FUEL PURPOSES à MORE LAND LEFT FOR FOOD
- BY INCORPORATING THE GLYCERYL MOIETY NO NEED TO HANDLE A BYPRODUCT
- „TBK” CAN BE PRODUCED IN PRESENTLY OPERATING BD PLANTS
- CONTINUOUS PROCESS, LOWER MANUFACTURING COSTS
- WASTELESS, ECO-FRIENDLY TECHNOLOGY, NO SEWAGE, MILD REACTION CONDITIONS
- GLYCEROL OF PRESENT PROCESSES AS FEEDSTOCK
- LOWERED IODINE NUMBER à MORE STABILE FUEL (BETTER OXIDATION RESISTANCE) à SUNFLOWER/SOYA AS FEEDSTOCK à TRIPLING AVAILABLE STARTING MATERIALS FOR BIOFUEL
- 5% GREATER VOLUMETRIC ENERGY DENSITY AS COMPARED TO BD
- 100% BIO RENEWABLE AS COMPARED TO BD ( FOSSIL-DERIVED METHANOL IN FAME!)
- MORE FAVOURABLE COLD PROPERTIES (LOWER CP/PP)
D. EVALUATION OF THE NEW BIOFUEL
EVALUATION IS UNDER WAY. SOME PRELIMINARY FINDINGS:
o VISCOSITY: 5 – 6 cSt AT 40°C
o CP: – 13°C
o COPPER STRIP CORROSION: CLASS 1A
o MOTOR TESTS (10% BLEND WITH PETRODIESEL): SAME AS BIODIESEL, WITH BETTER TORQUE VALUES
o EMISSIONS: SUPERIOR TO BIODIESEL (50% LESS SMOKE)
THIS NEW FUEL (STARTING FROM RAPESEED OIL) MEETS GERMAN „RK-QUALITÄTSTANDARD”
(„QUALITY STANDARD FOR RAPESEED OIL AS FUEL”). HOWEVER, ON ACCOUNT OF ITS LOWER (GREATLY DIMINISHED) VISCOSITY IT IS SUITABLE FOR ALL KINDS OF DIESEL ENGINES WITHOUT PREHEATING (CONTRARY TO NEAT – „SVO” – RAPESEED OIL!)
SINCE „TBK-BIODIESEL” CONTAINS SUCH COMPONENTS (MODIFIED TRIGLYCERIDES) WHOSE CORRESPONDING COMPOUNDS (TRIGLYCERIDES) ARE VERY MUCH LIMITED BY TRADITIONAL BIODIESEL STANDARDS, STANDARDISATION OF THE NEW BIOFUEL – BASED ON THE ABOVE GERMAN DIN STANDARD – IS IN PROGRESS.

Tests performed: in the Institute Workshop, accredited by ENERGOTEST Kft ( Hungary)
Date: 13.07.2007.
Type of motor: PERKINS 1104
Engine brake: D-4 type water-brake
Measuring and qualifying system: Energotest
Fuel consumption meter: AI 2000 gravimetric
Types of fuel: -10 % TBK-K41 + 90 % petrodiesel
- 10 % TBK-K42 + 90 % petrodiesel
- 10 % TBK-K44 + 90 % petrodiesel
- 10 % RME + 90 % petrodiesel (as against)
Test purpose: Evaluation of novel biofuel „TBK” by comparing regulatory characteristics under full load
Evaluation of test:
1. Mixtures of biofuels and petrodiesel were tested under full load with engine brake. During the tests no malfunctions arose. The tests for the above-mentioned mixtures were carried out along with a „blind test”.
2. It can be concluded that the maximum effective power at 2100 rpm. were the same for all samples (Peff K41 = 64,8 KW, Peff K42 = 64,2 KW, Peff K44 = 63,6 KW és Peff RME = 64,6 KW, respectively). The same is true for the maximum torques at 1400 rpm. (MK41 = 320,3 Nm, MK42 = 322,2 Nm, MK44 = 319,5 Nm, MRME = 319,1 Nm, respectively).
The minimum values of specific fuel consumption were identical: bmin K41 = 287,1 g/KWh, bmin K42 = 287,7 g/KWh, bmin K44 = 287,7 g/KWh, bmin RME = 300,0 g/KWh, respectively.
3. Sample TBK-K41 was manufactured of rapeseed oil, TBK-K42 of sunflower oil, TBK-K44 of rapeseed oil, under modified parameters, RME is for „Rapeseed Methyl Ester”.
Recommendations:
It is to be stressed that the above values were registered under prevailing conditions without repetition. I recommend long-term tests along with field tests. Also, I propose qualification tests according to biofuel standards in an independent and accredited laboratory.

E. ECONOMY OF „TBK-BIODIESEL” PROCESS
COMPARISON OF PRESENT BIODIESEL PROCESSES AND THE NOVEL TBK-BIODIESEL PROCESS:
IN PRESENT PROCESSES THERE IS A 12 – 13% LOSS IN TERMS OF STARTING BIOMASS TRIGLYCERIDES, ON ACCOUNT OF GLYCEROL FORMATION. IN THE TBK-PROCESS THERE IS NO SUCH LOSS, AS THE GLYCERYL FUNCTION IS RETAINED IN ONE OF THE FUEL COMPONENTS. MOREOVER, OWING TO THE INCORPORATION OF THE TRANSESTERIFYING AGENT, THERE IS AN EXTRA MIN. 10% GAIN IN TERMS OF FUEL YIELDS. SO ALTOGETHER THE TBK PROCESS HAS AN 10-15% EDGE ON TRADITIONAL PROCESSES. CONSIDERING A 100.000 TON/Y BIODIESEL PLANT THIS EXTRA MASS OF FUEL AMOUNTS TO APPR. USD 10 MILLION IN EXTRA REVENUES.
