The fermentation step is at the heart of the Jupeng Bio process technology. The syngas is introduced into the Jupeng Bio patented fermentation process, where naturally occurring bacteria combine them efficiently, selectively and rapidly to produce bioethanol. The fermenter is agitated to aid gas-liquid transfer. The Jupeng Bio fermentation process takes only a few minutes, compared to 1-3 days for conventional, first generation and cellulosic fermentation processes. The Jupeng bio-chemical synthesis takes place at low temperature and pressure and with high yield and selectivity. This high performance, coupled with tolerance to variations in syngas composition and to common catalyst poisons, means fewer process steps, high energy efficiency, low bioethanol production costs and attractive investment returns.
Nutrients are added for providing for cell growth and automatic regeneration of the biocatalyst. Jupeng Bio's proprietary combination of microorganism, nutrients, process design and conditions produces bioethanol at industrial quantities and at a commercially attractive and competitive cost.
The microbe used in the Jupeng Bio process technology is a naturally occurring micro-organism (i.e. it is not genetically modified). The bacteria efficiently convert the syngas into ethanol and extract the carbon and energy they require for cell division and metabolism directly from the syngas. As the bacterium is anaerobic, the bacteria die upon exposure to oxygen. It poses no threat to humans, animals or the environment. Jupeng Bio is only required to follow Biosafety Level 1 procedures when handling the culture, which is the lowest level of safety precautions.
Most of the syngas is converted to bioethanol. The unconverted syngas (vent gas) is cleaned and combusted to generate additional renewable power. Sufficient heat and power is generated by the integrated process to meet the entire energy needs of the process with surplus available for third party use.
