Optimization of a Commercial Waste Wood to Syngas and Biofuels Gasification Process

伍德兰生物燃料公司该公司开发了一种低成本的工艺技术，利用气化和一系列催化反应将废木材和其他生物质转化为可再生燃料，并获得了专利。Woodland的示范工厂位于安大略萨尼亚的生物工业创新中心，2019年，加拿大联邦政府宣布投资近500万美元，使Woodland能够建立其第一个商业工厂。在准备此次发布时，Woodland寻求确定用于其气化过程的废木材原料的最佳供应。确定最佳的废木材来源至关重要，因为原料的质量决定了最终产品的产量和质量，并直接关系到商业工厂的设计和运营。 气化是一种热化学过程，其中生物质被转化为合成气体（合成气）。许多气化工艺需要高达1300 °C的高温，但Woodland的工艺利用下游催化重整器来降低驱动气化转化所需的温度。气化过程可用于热和电力应用，合成气成分可用作生产可再生化学品（如氨和燃料）的构件。由于这一前景，全球对气化产生了极大的兴趣。 然而，通过气化将生物质转化为燃料和化学品的持续进展的一个关键瓶颈是生物质原料（包括废木材）的质量和物流。在气化过程中利用不同类型的生物质在原料灵活性方面对Woodland有利，但这种好处带来了商业设施设计和操作方面的挑战，以及对合成气质量的潜在负面影响。 总体目标是评估安大略可用的废木材的质量，并使用这些结果来通知林地生物燃料的商业气化设施的设计和操作。

Woodland Biofuels Inc. has developed and patented a low-cost process technology using gasification and a series of catalytic reactions to convert waste wood and other sources of biomass into renewable fuels. Woodland's demonstration plant is located at the Bioindustrial Innovation Centre in Sarnia, Ontario and in 2019, the federal government of Canada announced an investment of nearly $5 million to enable Woodland to build its first commercial plant. In preparation of this launch, Woodland seeks to determine the optimum supply of waste wood feedstock(s) to be used in their gasification process. Identification of the best waste wood sources is of critical importance as the quality of the feedstock drives yield and quality of end products and has direct relevance to how the commercial plant will be designed and operated. Gasification is a thermochemical process in which biomass is converted into synthesis gases (syngas). Many gasification processes require high temperatures, as much as 1300 °C, but Woodland's process takes advantage of a downstream catalytic reformer to reduce the temperature needed to drive the gasification conversion. The gasification process can be harnessed for heat and power applications and syngas constituents can be used as building blocks for production of renewable chemicals such as ammonia and fuels. Because of this promise, there is great interest globally in gasification. However, a key bottleneck to the continued progress of biomass conversion to fuels and chemicals via gasification is the quality and logistics of biomass feedstocks, including waste wood. Utilization of different types of biomass in a gasification process can be beneficial to Woodland in terms of feedstock flexibility, but with this benefit comes challenges around design and operation of the commercial facility as well as potential negative consequences on the quality of the resulting syngas. The overall goal is to evaluate the quality of waste wood available in Ontario and to use these results to inform the design and operation of Woodland Biofuel's commercial gasification facility.
