From wood biomass to high-value liquid product

Ensyn’s patented RTP technology is a processing system that uses heat to thermally crack carbon-based feedstocks such as wood biomass (cellulose, lignin) into high yields of a higher-value liquid product. Dried wood is typically converted to approximately 75% (by weight) liquid with the balance converted to combustible gases and char.  Relative yields can be varied in response to customer product requirements. RTP is the only known commercial technology, worldwide, that can convert wood and other woody biomass to such high yields of liquids.

The key innovation of RTP is processing speed

With RTP, conversion typically takes place in less than two seconds. This allows for the production of new, higher value products, at high yields and with low capital costs.

The core RTP process does not employ high temperatures or excessive operating pressure

The RTP pyrolysis process is based on the application of a hot “transported” bed (typically sand) that is circulating between two key vessels. Feedstocks, such as wood residues, are subjected to fast, intimate contact with the hot sand for under a few seconds, resulting in the thermal cracking of the feedstock to gases and vapours. Product vapours are rapidly quenched, or cooled, and recovered as a light liquid product.

RTP represents a close analogue to equipment used in refineries worldwide

Ensyn’s RTP process is an analogue to Fluid Catalytic Cracking, or FCC, a very common and mature process used in most refineries around the world. An FCC system circulates catalyst in a closed loop between two key vessels in order to convert vacuum gas oil to gasoline.  Ensyn uses a similar mechanical process, but typically circulates readily-available sand while converting wood residues to high yields of a light liquid product.
