The R&D team of Green Harvest Energy（abbr GHE）generates high-quality synthesis gas and hard carbon negative precursor through high-temperature rapid pyrolysis of biomass resources, and produces high-value green methanol and hard carbon negative, which are applied to shipping industry, green chemical industry and sodium ion battery respectively. The direct heat pyrolysis gas production process with ceramic ball as solid heat carrier circulation overcomes the problems of poor temperature control, low gas production rate and small scale of biomass gas production. Compared with biomass air gasification, fermentation gasification and pure oxygen gasification, it has the advantages of mature technology, short processing cycle and high product value.
