Mechanism of the hydropyrolysis of Manvers coal
… pressures of nitrogen (pyrolysis) and hydrogen (hydropyrolysis). All products were investigated. Pyrolysis of coals involves the transfer of hydrogen atoms from one part of their structure to another. In the above experiments there was no way of labelling the hydrogen or of distinguishing between …

Lab-scale fast-hydropyrolysis and vapor-phase catalytic hydrodeoxygenation for producing liquid fuel range hydrocarbons from intact biomass
… heated in a hydrogen environment to produce fast-hydropyrolysis vapors that are catalytically upgraded in downstream hydrodeoxygenation (HDO) to produce hydrocarbons. This process has been modeled to have high carbon and energy efficiencies of ~70% and ~75%, respectively.</p> <p>This dissertation …
