摘要： This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.

摘要： This specification discloses a process to convert a converted lignin feedstream to an aromatic composition comprised of aromatic compounds. The process follows the steps of exposing the converted lignin feedstream to at least one catalyst in the presence of donated hydrogen atoms at an exposure temperature greater than 190° C. for a time of at least thirty minutes. The donated hydrogen atoms are donated from at least one hydrogen donating compound during exposure of the converted lignin feedstream to the at least one catalyst at the exposure temperature. The resulting products are comprised largely of aromatics.

摘要： This specification discloses an operational continuous process to convert lignin as found in ligno-cellulosic biomass before or after converting at least some of the carbohydrates. The continuous process has been demonstrated to create a slurry comprised of lignin, raise the slurry comprised of lignin to ultra-high pressure, deoxygenate the lignin in a lignin conversion reactor over a catalyst which is not a fixed bed without producing char. The continuous process further utilizes nanoparticles of a crystalline metal oxide. The conversion products of the carbohydrates or lignin can be further processed into polyester intermediates for use in polyester preforms and bottles.

摘要翻译： 本说明书公开了在转化至少一些碳水化合物之前或之后转化木质素 - 纤维素生物质中的木质素的操作连续方法。 已经证明连续方法产生由木质素组成的浆料，将由木质素组成的浆料提高到超高压，在木质素转化反应器中对不是固定床而不产生炭的催化剂脱氧木质素。 连续方法进一步利用结晶金属氧化物的纳米颗粒。 碳水化合物或木质素的转化产物可以进一步加工成聚酯中间体，用于聚酯预成型件和瓶子。
