Composition of bicyclic aromatic hydrocarbons in catalytic cracking gas oil

Abstract Extraction of the coal organic mass under the influence of organic dissolvent is a method of conversing coal into liquid products. The need for the further development of this technology is associated with the need to search for alternative direct liquefaction and gasification technologies for obtaining alternative fuel products. The paper presents the analysis results of hydrocarbon fractions 112-400 °C, obtained by joint heat treatment of coal and catalytic cracking heavy gas oil according to some quality indicators of traditional fuels. In general, according to some indicators this product is close to boiler fuels. But aromatic hydrocarbons and olefins predominate in the extraction products if we take into account chemical structure. So, it requires their hydrogenation improving.

Desulphurization by reactive adsorption was studied on sand abrasive blasting grit/ bentonite. The adsorbent was characterized by determining the composition, adsorption isotherms, specific surface area, pore volume and average pore diameter. Adsorption experiments were performed in continuous system at 260�300oC, 25 atm and volume hourly space velocities of 1-2 h-1. The efficiency of adsorption was evaluated at desulphurization of a synthetic reaction mixture and a catalytic cracking gas oil.

Zeolite Modification

The data of the cracking of vacuum gas oil (VG) and a mixture of VG with fuel oil (M-100) on HLaY zeolite catalyst based on acid-activated kaolinite of the Pavlodar deposit modified by aluminum are presented. The synthesis of the kaolinite matrix and the HLaY zeolite catalyst with its use, the physicochemical and acid characteristics of the catalyst and its constituent components, and the fractional and hydrocarbon compositions of vacuum gas oil are described. High mesoporosity of the H-form of the used kaolinite (86.2%), modified by aluminum of the H-form (84.1) and the HLaY catalyst (80.1%), which provide the activity of the sample in cracking of the mixture with a yield of 32.6% gasoline and 25.9% light gas oil (LG) at 4500С and in cracking of VG a yield of 38.2% gasoline and 29.4% LG at 5000С. The gasolines of cracking of LG contain an increased content of iso paraffins (up to 20.2%) and a low content of aromatic hydrocarbons (24.1%), which makes the catalyst attractive for cracking a mixture of VG with fuel oil. Key words: catalytic cracking, kaolinite, vacuum gas oil, fuel oil, zeolite, modification.

This article presents the results of studies in the field of synthesis of water-soluble salts of oligomethylene aryl sulfonates synthesized using aromatic hydrocarbons contained in the gas oil fraction of the catalytic cracking process of oil as raw materials. Based on the synthesized various salts of oligoaromatic sulfonic acids (sodium, potassium, ammonium salts), solutions of various concentrations (35; 75; 150; 200 mg/l) were prepared and their effect on the vital activity of sulfate-reducing bacteria at a temperature of 30…32 °С for 7…14 days was studied. It was found that complex salts synthesized on the basis of oligomeric sulfonic acids of aromatic hydrocarbons of the gas oil fraction (N-1, N-2, N-3) at a concentration of 150 mg/l exhibit more than 90%, and at a concentration of 200 mg/l, 100% bactericidal effect and completely inhibits the growth of bacteria. It was revealed that the synthesized salts of sulfonic acids exhibit a relatively higher antimicrobial activity against SRB than the industrial bactericidal inhibitors AMDOR-IK-7 and AMDOR-IK-10 taken as a reference. Based on the studies, it was found that the synthesized salts of oligosulfonic acids completely inhibit the growth of sulfate-reducing bacteria at much lower concentrations compared to the industrially used bactericidal inhibitors taken as a reference. In particular, at a concentration of 150 mg/l, the bactericidal effect is more than 90% against 75…80% for the standard.

Petroleum Distillates

Acid tar is a resinous substance, which in most cases has a viscous structure. They are obtained as a result of sulfuric acid purification of petroleum distillates, oil residues, in the production of sulfonate additives, in the sulfonation and purification of oils, paraffins, kerosene and gas oil fractions and other petroleum products from aromatic hydrocarbons. Until recently, this type of waste was temporarily accumulated in specially designated areas - acid tar storage ponds, which were located near the oil refinery, which had a significant impact on the environment. The paper considers the process of formation of acid tar on the example of the production of sulfonate additives. The composition of the mixture of acid tar and sulfonate sludge was evaluated, and the hazard class of this type of waste was determined. Methods of utilization of acid tar are studied and a method of utilization of acid tar for the considered production is proposed.
