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粘度和密度太高，无法通过管道运输。这个问题通常是通过掺入溶剂来解决的，这会增加对管道能力的需求，并带来相关的环境和经济劣势。该项目的工业合作伙伴加拿大辛克鲁德有限公司生产部分升级的原油，适合在管道中直接运输。这项技术包括流体焦化工艺，在该工艺中，重质原料被裂解成较轻的产品。该项目旨在评估可能影响预期产品产量的一些参数。研究结果将有助于理解工业流体焦化装置中的过程，并有助于其优化。更高的工业焦化目标产品产量意味着更有效地利用提取的沥青，减少尾矿量，降低能源需求，从而减少油砂作业的排放。
