Bitumen extracted from Canadian oil sands is too viscous and dense for transportation in pipelines. The problem is typically addressed by admixing with solvents, which increases the demand for pipeline capacity and imposes associated environmental and economic disadvantages. The Industrial Partner of this project, Syncrude Canada Ltd., produces partially upgraded crude oil that is suitable for direct transportation in the pipelines. The technology includes a fluid coking process, in which heavy feed is cracked to lighter products. The project aims to assess some parameters, which possibly impact the desired product yield. The results will be useful to understand the processes occurring in the industrial fluid coker and contribute to its optimization. Higher target product yields from the industrial coker imply more efficient use of the extracted bitumen, reduced volumes of tailings, lower energy demand, and thus emission reduction in oil sands operations.

从加拿大油砂中提取的沥青太粘太密，无法通过管道运输。该问题通常通过与溶剂混合来解决，这增加了对管道容量的需求并带来了相关的环境和经济缺点。该项目的工业合作伙伴Syncrude Canada Ltd.，生产适合在管道中直接运输的部分改质原油。该技术包括流化焦化工艺，其中重质进料裂解成较轻的产品。该项目旨在评估一些可能影响预期产品产量的参数。研究结果将有助于理解工业流化焦化装置中发生的过程，并有助于其优化。来自工业焦化器的更高的目标产物产率意味着更有效地使用提取的沥青、减少的尾矿体积、更低的能量需求，并且因此减少油砂操作中的排放。
