“…Die Gesamtreaktion hängt vom eingesetzten Katalysator ab, wobei aufgrund ihrer geringen Kosten häufig Übergangsmetalle (insbesondere Nickel) 28 verwendet werden. Die ATR ist ein effizientes Verfahren, das jedoch eine geringere Wasserstoffausbeute aufweist als die Dampfreformierung 29.…”

Wasserstoff wird zurzeit überwiegend aus Erdgas, Erdöl und Kohle hergestellt. Aktuell wird in der Forschung und der anwendungsnahen Entwicklung intensiv an neuen Verfahren für die Erzeugung und den Transport von regenerativ erzeugtem Wasserstoff gearbeitet. Für die chemische Industrie werden zudem neue Kohlenstoffquellen gesucht, wodurch sich die Wertschöpfungsketten auf dem Weg zur angestrebten Klimaneutralität drastisch verändern. Die vorliegende Arbeit zeigt, dass der Wasserstoffbedarf nur in den frühen Wertschöpfungsstufen erheblich zunehmen wird. Bei der Veredelung von Zwischenprodukten wird sich Bedarf nicht deutlich ändern, wenn davon ausgegangen wird, dass die heutigen Zwischenprodukte der industriellen organischen Industrie weitestgehend beibehalten werden. Für eine erfolgreiche Transformation der deutschen chemischen Industrie wäre es demnach von besonderer Bedeutung, eine optimale Balance zwischen dem Import regenerativ erzeugter Zwischenprodukte und der Bereitstellung von regenerativem Wasserstoff für die Veredelungsstufen zu den Endprodukten zu finden.

“…77 Due to these benets, coal gasication and carbon capture-based technologies are being combined. 78 The gasication of coal is the earliest way of producing hydrogen, which is created in outdated gas plants and comprises a signicant quantity of CO and approximately 60% hydrogen. 79 Coal, for example, has pyrolysis process following equations: [75][76][77][78][79] 3C (coal, patch, etc.)…”

“…The energy efficiencies of GSP, Shell, and Texaco are 48.89%, 47.2%, and 40.44%, respectively. Hussain et al [18] developed two standalone models to produce syngas from coal gasification and natural gas dry reforming. The two technologies are integrated in parallel and series to improve the process.…”

Environmental concerns surrounding the use of high-sulfur fuel oil (HFO), a marine fuel derived from refinery vacuum residue, motivate the exploration of alternative solutions. Burning high-sulfur fuel oil (HFO) is a major source of air pollution, acid rain, ocean acidification, and climate change. When HFO is burned, it releases sulfur dioxide (SO2) into the air, a harmful gas that can cause respiratory problems, heart disease, and cancer. SO2 emissions can also contribute to acid rain, which can damage forests and lakes. Several countries and international organizations have taken steps to reduce HFO emissions from ships. For example, the International Maritime Organization (IMO) has implemented a global sulfur cap for marine fuels, which limits the sulfur content of fuel to 0.5% by mass. In addition, there is a worldwide effort to encourage the use of low-carbon gases to help reduce greenhouse gas (GHG) emissions. There are several alternative fuels that can be used in ships instead of HFO, such as liquefied natural gas (LNG), methanol, and hydrogen. These fuels are cleaner and more environmentally friendly than HFO. The aim of this study is to develop a process integration framework to co-produce methanol and hydrogen from vacuum residue while minimizing the sulfur and carbon emissions. Two process models have been developed in this study to produce methanol and hydrogen from vacuum residue. In case 1, vacuum residue is gasified using oxygen—steam and the syngas leaving the gasifier is processed to produce both methanol and hydrogen. Case 2 shares the same process model as case 1 except it is concentrated on mainly methanol production from vacuum residue. Both models are techno-economically compared in terms of methanol and H2 production rates, specific energy requirements, carbon conversion, CO2 specific emissions, overall process efficiencies, and project feasibility while considering the fluctuation of vacuum residue feed price from 0.022 $/kg to 0.11 $/kg. The comparative analysis showed that case 2 offers an 86.01% lower specific energy requirement (GJ) for each kilogram (kg) of fuel produced. The CO2 specific emission also decreased in case 2 by 69.76% compared to case 1. In addition, the calculated total net fuel production cost is 0.453 $/kg and 0.223 $/kg at 0.066 $/kg for case 1 and 2, respectively. Overall, case 2 exhibits better project feasibility compared to case 1 with higher process performance and lower production costs.
