“…The Rh/ZrO 2 and Ru/ZrO 2 catalysts also have high resistance to deactivation by carbon deposits formed during the steam reforming of butane at 773 K and low steam/butane ratios [46]. The low rate of formation of carbon deposits on nickel catalysts in the steam reforming reaction of methane and its mixtures with propane at temperatures of 543-623 K and low steam/C ratios < 1 is explained by the high dispersion of nickel on the support [47][48][49].…”

Steam reforming of n-butane has been studied in a membrane reactor at temperatures of 673-823 K, feed hourly space velocities of 1800 and 3600 h-1 , and steam/butane ratios of 3, 5 and 7. Under selected conditions, the steam conversion is accompanied by the formation of carbon deposits, whose yield decreases with increasing steam excess. However, with an increase in steam excess, its negative effect on H 2 recovery through the membrane increases. Comparative experiments with the "non-membrane" reaction at a constant steam/butane ratio equal to 5 have shown that butane conversion to the target products increases in the membrane reactor and the rate of carbon deposits formation decreases. When replacing the sweep gas by the vacuum conditions in the permeate side, there is a further decrease in the rate of carbon deposits formation and an increase in the butane conversion in the main reaction. With an increase in feed hourly space velocity from 1800 to 3600 h-1 , the rate of carbon deposits formation and its dependence on temperature increase. At an hourly space velocity of 1800 h-1 , the rate of formation of carbon deposits is two to three times lower and varies slightly with temperature. Under these conditions, the butane conversion is close to 100%; about 80% of H 2 formed is recovered from the reaction mixture, and at vacuum conditions in the permeate side, the H 2 recovery is 95%.

“…The direct use of APG and wet gas as power generation fuel is limited by its low methane content and unstable gas composition. Wet gas contains higher hydrocarbons which can cause thermal regime failure in gas turbines [4]. The low heat content of APG and wet gas may affect the gas turbine's performance.…”

<span lang="EN-GB">Oil fields produce associated petroleum and wet gas, which can be mixed with commercial natural gas as fuel. Associated petroleum and wet gas are a low cost, low quality fuel, whereas commercial natural gas is the opposite. Two parameters are affected by this mixture: the fuel cost and the power – steam output of gas turbine – heat recovery steam generators. This research develops a Unit Commitment and Optimal Power Flow model based on Mixed Integer Nonlinear Programming to optimize combined heat and power cost by considering the optimal mixture between associated petroleum - wet gas and commercial natural gas. A thermodynamic model is used to represent the performance of gas turbine – heat recovery steam generators when subjected to different fuel mixtures. The results show that the proposed model can optimize cost by determining the most efficient power – steam dispatch and optimal fuel mixture. Furthermore, the optimization model can analyse the trade-off between power system losses, steam demand and associated - wet gas utilization. </span>

“…Therefore, there is a need for alternative methods for on‐site processing of flare gas. Low‐temperature steam conversion (LTSC) of C 2+ ‐hydrocarbons into methane‐rich gas is considered as one of the promising alternatives. The process is carried out at a temperature of 200‐350°C and low steam to carbon ratio (H 2 O/C C2+ mol.…”

According to the thermodynamics, these operating conditions provide complete conversion of C 2+ ‐hydrocarbons, methane yield higher than 80 vol% on the dry basis, low СО 2 and H 2 content in the products and the decrease in the amount of water to be vaporized which improves the efficiency of the process . The Brutto reaction of the LTSC can be written in the following form:

Low‐temperature steam conversion (LTSC) of a methane‐butane mixture (95% methane and 5% butane) into a methane‐rich gas over an industrial Ni‐based catalyst has been studied with the following reaction conditions: temperature 200–320°C, pressure 1 bar, gas hour space velocity 1200–3600 h–1, and steam to carbon ratio 0.64. A three‐step macrokinetic model has been suggested based on the kinetic parameters found. The model includes the following reactions: (1) irreversible steam reforming; (2) CO2 methanation, which occurs in a quasi‐equilibrium mode at temperatures above 260°C; (3) hydrogenolysis of propane and butane, which is essential at temperatures below 260°C. Steam reforming was shown to limit the overall reaction rate, whereas hydrogenolysis and CO2 methanation determined the product distribution in low‐ and high‐temperature regions, respectively. Temperature dependencies of the product distribution for the LTSC of a model ternary methane‐propane‐butane mixture (85% methane, 10% propane, and 5% butane) have been successfully simulated using the three‐step model suggested.
