Regenerative Syngas for Multipurpose Fuels and Feedstocks

Advanced Renewable

Regenerative Syngas (RS) is syngas (CO and H2), which is produced from onboard carbon capture, such as using the FlueTrap and OCCYRE reactor, and offboard carbon capture through the photosynthesis process of plants into biomass. This is to differentiate syngas produced from fossils such as coal and natural gas, and renewable syngas from biomass. I have previously uploaded detailed production here: https://lnkd.in/gQcndYt2

Two goals can be achieved at once by using this RS, firstly, industrial emissions, power plants and other emission sources can be captured and do not pollute the earth's atmosphere, secondly we can obtain raw materials for low cost fuel whose sources are abundant. So what lind of use can this RS in current technology?

The diagram below is a usage that we have reviewed and tested some of them, starting from the bottom right corner. Internal Combustion Engine (ICE), both petrol and diesel, can have their fuel substituted with RE. RE can also be a feedstock for various chemical industries which currently depend on fossil raw materials.

RS can produce direct electricity very effectively using Fuel Cells technology, especially Solid Oxide Fuel Cells (SOFC). The most widely used is when RS is used to produce Advanced Fuels. It can be in the form of oxygenates such as methanol, ethanol, Dimethyl Ether (DME), hydrocarbons such as gasoline, diesel, jet-fuel, LPG, or to produce carbon-free fuels such as hydrogen and ammonia.

Because this RE is produced using a special gasification reactor, the OCCYRE reactor - namely a reactor that can facilitate the Boudouard reaction (C+CO2==>2CO) effectively, at temperatures above 800 degrees Celsius, there is potential for other energy that can also be processed, namely energy from waste heat.

The simplest thing is to use this waste heat for heating or air conditioning, and for water heating. What's even more sophisticated is that the waste heat can still be used to produce more electrical energy. Mature technologies can use an Organic Rankine Cycle (ORC) microturbine, or it can also use a Thermo Electric Generator (TEG).

From the examples of RE utilization below, we can see that whatever form our energy needs - they can actually be met from RE which is produced, among other things, from raw materials in the form of CO2 emissions. What does this mean? two big problems in the world today - the solutions are before our eyes, namely the problem of CO2 emissions which is very worrying because of its impact on global warming, climate change, extreme weather, etc. and energy security problems which have reached a critical point in a number of countries.

The solution to these two big problems is the same, we capture the CO2 emissions and process them into basic energy. The simplest thing for this is to start processing them into Regenerative Syngas.
