“…The common industry practice is to use energy intensive and costly pretreatment technologies such as coking and ebullated-bed hydroprocessing to remove heteroatoms and metals. The products from these processes require further processing to produce clean transportation fuels that meet stringent environment regulations (Gulyaeva et al 2017;Ng et al 2015;Zaikin and Zaikina 2016;Zhang et al 2017).…”

A Canadian in situ oilsands bitumen-derived vacuum residue (VR) was subjected to supercritical fluid extraction and fractionation (SFEF) into 13 extractable fractions and an unextractable end-cut and characterized by positive-and negative-ion electrospray ionization (ESI) Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The results of negative-ion ESI FT-ICR MS showed that the N 1 class species was the most abundant and the multifunctional group compounds, such as class species became abundant as the SFEF fraction became heavier. In positive-ion ESI mode, the relative abundance of N 1 class species decreased gradually in the heavy SFEF fractions while that of multifunctional group compounds increased. The relative abundance of N 4 V 1 O 1 increased dramatically in heavy fractions and the end-cut. The distributions of polar heteroatom species of VR derived from oilsands bitumen were similar with those of VR derived from the Venezuela Orinoco extra heavy oil.

Global hydrogen production contributes significantly to carbon dioxide emissions due to reliance on fossil fuels. This study aims to integrate and model various upstream and downstream processes to facilitate concurrent hydrogen production, underground storage, CO2 utilization, and electricity generation. The first part of this paper focuses on modeling gasification and CO2 capture processes, supplemented by an economic analysis to estimate critical capital and operating costs for design, scale-up, and integration considerations. The second part of this work shows how CO2-plume geothermal systems and power generation plants can complement gasification and CO2 capture processes to create a sustainable energy system. Key findings reveal a H2/VR ratio is 0.24 % wt/wt with a CO2 intensity is 3 % wt/wt. The CO2 capture process achieves a capture rate of 97%, with an initial CO2 flow rate of 582.0 kg/s and a captured CO2 flow rate of 565.8 kg/s. Additionally, the levelized costs of H2, with and without carbon capture, are determined as 1.795 $/kg and 1.684 $/kg, respectively. The CO2-plume geothermal model demonstrates varied outcomes, with the 1000 md scenario exhibiting the lowest CO2 sequestration due to its high average CO2 flow rate, while the 25 md scenario produces the most water owing to low permeability values. Notably, the 250 md and 1000 md scenarios achieve the highest and second-highest average power output, attributed to high CO2 flow rate, low water cut, and prolonged maintenance of CO2 in a supercritical state. This research provides valuable economic and technical insights that support the transition towards a low-carbon hydrogen future. The findings pave the way for more sustainable and efficient energy solutions.
