Abstract

In the current petroleum refining scenario, many refineries end up with surplus naphtha which is either absorbed into the gasoline pool or exported at unattractive prices. Therefore, several options for naphtha valorisation are currently being explored. The usage of Liquified Petroleum Gas (LPG) as a fuel in heating appliances, cooking equipment and automobiles is rapidly increasing. The high specific calorific value, high octane number, clean and efficient combustion of LPG distinguish it as an extremely promising fuel of the future. In the current work, tungstophosphoric acid (TPA) supported on four different mesoporous silica supports were investigated as mesoporous superacids for hydroconversion of refinery naphtha using -heptane as a model feedstock. The varied levels of interactions of prepared mesoporous silica with tungstophosphoric acid catalysts were observed to have a prominent effect on the strength of the acid sites generated on silica surfaces and as a result affected heptane hydroconversion activity and selectivity of isomerized and cracked products. Interestingly, activity could be tuned towards selective cracking or isomerization-cracking by selection of a suitable topology of mesoporous silica. Hexagonal Mesoporous Silica (HMS) and plugged SBA-15 supported TPA catalysts demonstrated high -heptane conversion activity and isomerization selectivity whereas KIT-6 and SBA-15 supported TPA catalysts demonstrated high cracking selectivity to LPG.

摘要

在当前的石油炼制场景中，许多炼油厂最终会产生过剩的石脑油，这些石脑油要么被吸收到汽油池中，要么以不具吸引力的价格出口。因此，目前正在探索几种石脑油增值的选择。液化石油气（LPG）在加热设备、烹饪设备和汽车中作为燃料的使用正在迅速增加。LPG的高比热值、高辛烷值、清洁高效燃烧使其成为未来极具前景的燃料。在当前的工作中，研究了负载在四种不同介孔二氧化硅载体上的钨磷酸（TPA）作为介孔超强酸，以正庚烷为模型原料对炼油厂石脑油进行加氢转化。观察到制备的介孔二氧化硅与钨磷酸催化剂的不同相互作用水平对二氧化硅表面产生的酸位强度有显著影响，从而影响正庚烷加氢转化活性以及异构化和裂化产物的选择性。有趣的是，通过选择合适的介孔二氧化硅拓扑结构，可以将活性调整为选择性裂化或异构化 - 裂化。六方介孔二氧化硅（HMS）和堵塞的SBA - 15负载的TPA催化剂表现出高正庚烷转化活性和异构化选择性，而KIT - 6和SBA - 15负载的TPA催化剂表现出对LPG的高裂化选择性。
