As shown by X-ray diffraction analysis, the ash residue after the oxidation of the catalyst concentrate contains both individual molybdenum oxide (MoO3) and mixtures of double (NiMoO4, V2MoO8, NiV2O6, Na0.76V6O15) and triple (Fe4V2Mo3O20) oxides in the form of alloys. An efficient procedure is the pretreatment of the ash residue with 65% HNO3, followed by the treatment of the resulting suspension with a mixture containing 10% NH4OH and 5% (NH4)2CO3.

Catalyst particle suspensions were prepared from inverse emulsions of aqueous solutions of the precursors (ammonium paramolybdate, cobalt nitrate or acetate) directly in the feed (in situ). Two procedures were used for preparing the promoted catalyst: consecutive or simultaneous addition of the precursors to the dispersion medium. The toluene-insoluble particles (TIPs) containing the spent catalyst had the size from 380 to 410 nm and contained the MoS2, МоО3, and Co9S8 crystalline phases. The cobalt-promoted dispersed catalyst exhibits the maximal activity in hydrodesulfurization and hydrogenation at the cobalt content of 33 at. %. The effect observed is due to the formation of a variable-composition Мо–Со–S phase, which cannot be identified by X-ray diffraction, on the surface of MoS2 particles. A further increase in the promoter concentration leads to blocking of the MoS2 particle surface with Co9S8 crystals, which, in turn, leads to a decrease in the catalyst activity in hydrodesulfurization and hydrogenation of high-molecular-mass feed components, to an increase in coking, and to a decrease in the fraction of paraffin–naphthene hydrocarbons in the hydrogenation product.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 10","pages":"1224 - 1231"},"PeriodicalIF":1.3,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143109057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of studying digenesis processes in the oil-bearing reservoir increased because they can affect porosity and permeability; thereby can affect hydrocarbon flow and accumulations. 73 samples (45 sandstone samples and 28 shale and thin bed carbonates) from six wells of Zubair Formation (upper shale and upper sand members) in Luhais oil field were selected and prepared for petrography inspection to detect mineral compositions of sandstone and diagenesis processes and its affections on the rocks. Eight samples were selected for X-ray diffraction analyses to detect clay mineralogy. Petrographic inspection shows that many postdepositional processes affected the sandstone of Zubair Formation at different stages because of continuous changes in physical and chemical conditions in the sedimentary environment one of which leads to increase porosity such as dissolution and some processes lead to decrease porosity such as compaction, alteration and cementation. As well as there are diagenesis processes played contrasted role that it leads to increase porosity in some places and decrease in others, such as bioturbation which leads to increase vertical porosity and permeability if fine grained bed overlaid by coarse grained beds; at bioturbation start the coarse grains of overlying bed fill the underlying borrow; where as it leads to decrease porosity when it happened in coarse grained bed overlaid by fine grained sediments. Although most of diagenesis processes are destructive, but Zubair Formation is considered one of the main oil reservoirs; because it has good textural maturity (most sand grains have good roundness, sorting and little mud content). So, it can be concluded that the main factors control reservoir quality are rock texture and intensity of diagenesis process not the quantity of diagenesis processes.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 8","pages":"956 - 963"},"PeriodicalIF":1.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The work shows heavy crude oil with an asphaltene content of 2.49 wt % taken from the Samawah oil refinery in southern Iraq was deasphalted using a homemade flow system with several variables. The significant variables impacting the deasphalting process were identified using the central composite design (CCD) and response surface method (RSM). The optimum conditions of the deasphalting process are n-heptane solvent, a flow rate of 31 mL/min, a mixing coil length of 172 cm, a temperature of 32°C, and a time of 3 s. It was determined that the impact of using variables occurs in the following order: mixing coil length > temperature > solvent flow rate > time in n-heptane solvent. The experimental and theoretical efficiencies of the deasphalting technique for heavy crude oil were found to be 57.94 and 56.26%, respectively.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 8","pages":"1055 - 1062"},"PeriodicalIF":1.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was conducted to determine the flue gas acid dew point of a furnace used to pre-heat the input of a crude distillation unit in a refinery. The furnace uses combination of fuel oil and fuel gas sourced from the refinery with a known elemental composition. Three scenarios were analyzed; fired from fuel oil, from fuel gas, and a combination of both. The third scenario is based on a day of which the feed rate of the unit was 5350 tons/day. Using the fundamental analysis of combustion chemistry and two methods of A.G. Okkes’ and Verhoff and Banchero’s, the theoretical acid dew point in each scenario was determined. It was 150.52 and 155.00°C in the latter scenario. The flue gas temperature was measured as 183°C. Hence, it was determined that the acid dew point was below the flue gas temperature. The determined results can be used as a benchmark to mitigate low-temperature corrosion in downstream equipment and to evaluate further thermal recovery if needed.","PeriodicalId":725,"journal":{"name":"Petroleum Chemistry","volume":"64 8","pages":"947 - 955"},"PeriodicalIF":1.1,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145121808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
