Abstract This study evaluates the construction of a production line for titanium catalyst based on three scenarios, one based on the chloride method with sol-gel synthesis (CP-SG) (case A), second case based on the sulfate process with hydrothermal synthesis (SP-H) (case B) and the chloride process with spray-pyrolysis synthesis (CP-SP) as third case (case C). Technical feasibility was tested through utilization of ilmenite feedstock in cycle’s production using three mentioned scenarios. The economic indicators such as net present value (NPV) and internal rate of return (IRR) were used to evaluate the economic performance. The results show that at 50,000 Ton/y production capacity, NPV at 15% discounting rate is 409 M$ for case A, and 424.7 M$, 422.7 M$ for cases B and C, respectively. The sensitivity analysis shows that the production cost and titanium catalyst selling price were the most sensitive input parameters.

钛铁矿纯钛催化剂生产周期的技术经济评价（以伊朗 Kahnooj 矿为例）

摘要 本研究基于三种情景对钛催化剂生产线的建设进行评估，一种基于氯化法溶胶-凝胶合成（CP-SG）（案例A），第二种基于硫酸盐法水热合成（ SP-H)（案例 B）和带有喷雾热解合成（CP-SP）的氯化物工艺作为第三种案例（案例 C）。技术可行性通过在循环生产中使用钛铁矿原料使用上述三种情况进行测试。使用净现值（NPV）和内部收益率（IRR）等经济指标来评价经济绩效。结果表明，在 50,000 吨/年的产能下，案例 A 的 15% 贴现率的 NPV 分别为 4.09 亿美元，案例 B 和 C 的 NPV 分别为 4.247 亿美元、4.227 亿美元。
