Bitumen produced from Canadian oil sand resources contains significant amounts of asphaltenes and heteroatoms. This refractory material must be first upgraded to synthetic crude in order to be processed in conventional refineries. One approach to bitumen upgrading involves "hydrocracking" of bitumen residues through simultaneous catalytic hydrogenation and cracking in an ebullated-bed reactor. This unit operation involves complex coupled multiphase (gas, liquid, solid) hydrodynamics, chemical kinetics, and transport phenomena making it difficult to design and optimize using traditional experimental analysis.

由加拿大油砂资源生产的沥青含有大量的沥青质和杂原子。这种耐火材料必须首先升级为合成原油，以便在常规炼油厂中加工。沥青改质的一种方法涉及通过在沸腾床反应器中同时催化氢化和裂化来“加氢裂化”沥青残余物。该单元操作涉及复杂的耦合多相（气体、液体、固体）流体动力学、化学动力学和输送现象，使得难以使用传统的实验分析进行设计和优化。
