Sharing our collection of news, issues, debates, etc. on bio-renewable chemicals

On our media pages we share links via tweets and the posterous blog to topics that are related to our world of bio-renewable chemicals. The focus of our company web pages continues to be dedicated on the conversion of biomass to chemicals (furfural) and energy.

Bio-rewable fuel additive for diesel/kerosene reduce emissions

The furfural molecule has a very high oxygen content. In addition, its derivatives are known to change the phase diagram of (e.g. diesel), so that mineral diesel can be blended e.g. with alcohols without forming emulsions. Already in earlier work and field trials, such additives have successfully reduced diesel emissions or suppressed e.g. the vapour pressure so ethanol-gasoline mixtures did not separate! The attached patent falls into this category of chemistry. 

Extract from US Patent #8,372,165

A diesel fuel blending component primarily comprised of 1,2-(ditetrahydrofuryl)ethane (DTHFE) along with a method of manufacture is presented. The blending component will reduce PM and other emissions in a diesel engine. The component is manufactured from C5 sugar sources by first converting to furfural, then furion, and then hydrotreated to the desired product.

Benefits

Diesel: For diesel fuels for compression ignition engines, in one embodiment, the DTHFE is used as an additive to improve cetane and cold flow properties of petroleum diesel or biodiesel (FAME) blends. Percentages considered additive blend levels of DTHFE are 0.1% to 5%. Blends in this range would also reduce exhaust particulates. In another embodiment, blends from 5% to 80% would add additional renewable content to the fuel and maintain the advantages of the additive blend levels. Most probably 10% to 30% blends would be used.

Kerosene: DTHFE blends with petroleum kerosene would provide renewable content to jet fuels without compromising freeze point and smoke point and other critical specifications. Blend ranges could be from 5% to 80%.

GreenEnergyPark™: Creating Wealth For Rural KwaZulu-Natal

DalinYebo requires R130,000,000 (R85,000,000 CAPEX, R45,000,000 Working Captial) for the development of the uThukela GreenEnergyPark™, which uses agricultural residues/biomass to produce a high-value bio-renewable chemical (Furfural) and electricity.

The GreenEnergyPark™ will provide the platform for a projected R350million pa business that brings additional profits to the farmlands and generates employment. It is set in uThukela District Municipality, the most western area of the KwaZulu-Natal province (South Africa). uThukela is a highly accessible (incl. rail), but its 11,500km2 agriculture area is under utilised. uThukela has a very high unemployment rate.

Our preferred biomass is corncobs and turning it into furfural and electricity is the core of the GreenEnergyPark™. The project is viable on the basis of the furfural production with a payback period of less than five years and an after tax IRR in the 20%s. The furfural sales will be secured via off-take agreements. In addition, the GreenEnergyPark™ will provide the infrastructure and electricity for other enterprises (most likely, but not exclusively) in the agri-processing sector and/or, alternatively, the development of a furfural-downstream processing cluster for the manufacture of other high-value bio-renewable chemicals.

We envisaged to finance the project as follows:

In an series-A round we wishes to raise R12,000,000 in exchange for 20-25% share holding in the uThukela GreenEnergyPark™ SPV. These funds would be used for the activities and the development of the legal documents that are required to secure the project debt.

The investor will have a first right of refusal to participate in the series-B finance, during which we shall raise the balance of the funding, which will consist of additional equity and the project loan. We already have expression of interest from project finance institutions who wish to provide the senior debt at prime or prime+1% on a 30:70 equity:debt gearing.

The uThukela GreenEnergyPark™ business plan expects a strong cash-flow, which should fund the working capital. As a contingency, however, we plan to raise working capital via a short term loan.

This is the first of five planned GreenEnergyPark™ developments in South Africa. It can be (a) replicated and (b) tailored to other crop (also forest) residues.

Cobelec™: Creating Wealth From Crop Residue

At the end of 3Q10, this business plan was runner-up in the first african cleatech investment competition and labeled ”investment ready” by the judges from UNFCCC Expert Group on Technology Transfer and other international and local experts (incl. IFC and IDC).

DalinYebo is the Xhosa word for Wealth Creation. We do this in the Cleantech space.

At DalinYebo we use Innovative Minds to convert biomass into chemicals and energy. More specifically we would like to introduce you to our Cobelec™ Start-up, a business that is based on the conversion of corncobs into electricity … and in the future to chemicals, also.
