The IH² Technology is a new process for direct conversion of solid biomass to ‘whole barrel’ hydrocarbon fuels. This process was developed by Gas Technology Institute (GTI). It uses proprietary catalysts from CRI Catalyst Company (CRI). Sub-licenses are available from CRI on a globally exclusive basis. The process is feedstock flexible, and has been demonstrated with wood, agricultural residues, algal biomass and others. The IH² process has two stages. In the first stage, biomass is processed under a hydrogen atmosphere at low pressure in the presence of a catalyst. The hydrodeoxygenated 1st stage product then enters the second stage, where the material is polished over a second proprietary CRI catalyst. These two integrated steps directly produce gasoline, kerosene and diesel hydrocarbon product with oxygen content below detection limits. C1-C3 light gas from the 1st stage are directed to a steam reformer where 100% of the required hydrogen for the process is generated. Since both the steps are quite exothermic, the process produces significant export energy. Liquid hydrocarbon yields of 92-157 gallons/ton biomass (on a dry and ash-free basis) are obtained, depending on the feedstock.

CRI/Criterion has deployed high-throughput tools for formulation of new catalyst compositions, and for testing the performance of the catalysts in several applications. This ability allows for screening of a large number of catalysts in a very short amount of time, significantly reducing the time required for catalyst development. The high-throughput screening ability has been proven in several areas of CRI/Criterion’s businesses, including chemicals and refining. High-throughput screening tools are equally, if not more, valuable in speedy deployment of biofuels and biochemicals from the lab to the market. Here we provide an overview of a program for rapid catalyst and process development to convert a mixed alcohol feed into gasoline and kerosene range hydrocarbons.
