Quality Syngas Catalytic Gasification Biomass

项目摘要

The gasification of biomass wastes represents a major thermochemical route to produce a high energy value hydrogen and methane rich syngas from a source which is renewable and CO2-neutral. Coupled with CO2 capture, the process offers a pre-combustion route to carbon capture sequestration for industrial power and electricity production. However, one of the major issues in the gasification process is the production of tar. Tar is a complex mixture of condensable hydrocarbons. The formation of tar causes major process and syngas use problems, including tar blockages, plugging and corrosion in downstream fuel lines, filters, engine nozzles and turbines. This proposal seeks to develop advanced triple function nano-nickel catalysts for, tar removal, enhanced hydrogen/methane production and CO2 capture and thereby produce high yield, clean, high calorific value syngas from the gasification of biomass/waste. Novel catalysts with homogeneous, well dispersed nano-Ni particles on a high-surface functional structured support, will be produced and examined in relation to the process conditions of gasification of biomass wastes for syngas quality in a continuous operation. The mechanisms of tar reactions, catalyst coke formation and sintering will be developed throughout the programme enabling catalysts to be designed to maximise and predict syngas quality from the process of biomass/waste gasification.The project benefits from the collaboration of a gasification system manufacturer and a catalysts development company who will aid the scale up of the catalyst preparation and trials in full scale gasification systems.

生物质废弃物的气化是一条主要的热化学路线，可以从可再生和二氧化碳中性的来源生产高能值氢和甲烷的合成气。与二氧化碳捕获相结合，该过程为工业电力和电力生产提供了一条燃烧前碳捕获封存的途径。然而，气化过程中的一个主要问题是焦油的生产。焦油是可凝聚碳氢化合物的复杂混合物。焦油的形成会导致重大的工艺和合成气使用问题，包括焦油堵塞、下游燃料管、过滤器、发动机喷嘴和涡轮机的堵塞和腐蚀。该建议旨在开发先进的三功能纳米镍催化剂，用于焦油去除、增强氢气/甲烷生产和二氧化碳捕获，从而从生物质/废物气化生产高产率、清洁、高热值的合成气。将在高表面功能结构载体上制备具有均匀、分散的纳米镍颗粒的新型催化剂，并在连续操作中考察生物质废物气化合成气质量的工艺条件。整个计划将开发焦油反应、催化剂焦炭形成和烧结的机制，使催化剂能够设计成最大限度地提高和预测生物质/废物气化过程中的合成气质量。该项目受益于气化系统制造商和催化剂开发公司的合作，后者将帮助扩大催化剂制备的规模，并在全规模气化系统中进行试验。
