Understanding the origin of fine particulate matter is essential to proposing proper strategies for heavy haze mitigation in Shanghai, China. In this study we used the Particulate Matter Source Apportionment Technology in Comprehensive Air Quality Model with Extensions to quantify the impacts of emissions on the concentrations of fine particulate matter (PM2.5) and its important components in Shanghai during heavy haze episodes in late autumn (6-22 November 2010). The factors considered here are regions of Shanghai and its surrounding areas, long-range regional transport, and different local emission categories. The results indicate that industrial process is the dominant local contributor to total PM2.5 mass in the whole city except that at the urban center vehicle emission contributes slightly more. In addition, industrial process and vehicle emission are the major local contributors for nitrate in Shanghai, although at urban core the contribution from vehicle emission is remarkably larger. Generally, both local contribution and regional transport contribution could dominate a severe haze event in late autumn. However, the dominant contributor could either be local emission or regional transport, usually depending on the meteorological conditions. Therefore, particular attentions should be paid to the emission control in the upwind adjacent provinces, as well as in local areas, for developing effective strategies to reduce PM2.5 pollution in Shanghai. Key Points PM source apportionment in Shanghai is simulated using a regional model Regional transport plays an important role in haze formation in Shanghai Controlling emission from vehicle and industrial process is vital © 2013.

To improve the catalytic stability of alkylation desulfurization reaction, fluid catalytic cracking (FCC) gasoline was pretreated for alkaline nitrogen removal by extraction with distilled water or hydrochloric acid, followed by adsorption with D101 or NKC-9 macro-porous dry resin. The influences of pretreatment to the extent of desulfurization, and to the amount and molecular structure of residue sulfur in FCC gasoline, were investigated. The results show that, alkaline nitrogen compounds in FCC gasoline can be quickly and effectively removed by hydrochloric acid extraction and NKC-9 resin adsorption, in addition to that, NKC-9 resins can absorb trace amounts of sulfides. With the removal of alkaline nitrogen compound, the transfer rate of several major thiophene sulfides can achieve more than 90% in alkylation reaction of FCC gasoline.

The pre-hydrotreating catalyst LY-2010R for reforming feedstock with excellent activity and high space velocity operation was developed. The long running performance was investigated by comparing with the main domestic catalyst. The results revealed that the hydrodesulfurization and dearsenization activity for LY-2010R catalyst was slightly better than the contract catalyst, and the hydrodenitrogen activity was comparable with the contract catalyst. LY-2010R catalyst could used in high space velocity 12 h-1 condition, but also the catalyst could be used to process high sulfur or high nitrogen feedstocks.

The selective oxidative desulfurization was conducted with a feedstock of model gasoline consisting of thiophene and n-octane in an H 2O 2·HCOOH oxidative system over a Ti-MCM-41 catalyst. The operations were designed by the orthogonal design method with an L 9 (3 4) table. Experimental results show that the factors influencing the rate of desulfurization are reaction temperature, the reaction time, and the volume percent content of the hydrogen peroxide in order. Under the optimized operation conditions over Ti-MCM-41 catalyst: H 2O 2 volume fraction of 3% (v), reaction time of 40 min and reaction temperature of 50°C, the removal ratio of thiophene was 95.6%, and the gasoline yield was 98.7%. The activity of the catalyst has no dramatic deactivation after reusing it five times. In addition, the kinetics study indicates that this reaction is a pseudo first-order reaction with the activation energy of Ea = 40.18 kJ/mol. © 2012 Copyright Taylor and Francis Group, LLC.

The catalytic activity and performance in long operation of ZSM-5 catalyst for post-MTBE C4 aromatization in a fixed bed were studied. The results indicate that at the optimal reaction conditions of 380 °C, 2.0 MPa, WHSV of 2.0 h-1 and H2/oil volume ratio of 300, the conversion of olefin exceeds 99%, the yield of dry gas is less than 2.0%, the yield of C5+ is 35%-41%, the yield of LPG is 57%-64%, the yield of aromatic is 10%-12%, and the catalyst shows a stable performance. After 984 h running, the coke deposition on the catalyst is 11.56% and no deactivation of the catalyst is observed. The gaseous product is an excellent material for ethylene production.

Solid compound acid catalyst exhibited good sulphur transfer activity for catalyzing alkylation of thiophene with olefins. The effect of total acid amount including Brown acid and Lewis acid in solid compound acid catalyst with different loading ratio of silica and aluminum, load of compound acid, mass ratio of compound acids and calcine temperature on the catalyst activity was investigated. Solid compound acid catalyst showed the highest sulphur transfer activity with 93.7% conversion of thiophene under the condition of mass ratio of Si/(Si + Al) between 0.6 and 0.7 in load, 60% of compound acid on loading and the calcine temperature of catalyst between 500°C and 550°C. The hydrocarbon component hardly changed, olefine content decreased slightly and the octane value of gasoline reduced by 0.2 unit after the alkylation reaction.

Analysis on the variations of SARA content and metal content of the feedstock in delayed coking unit, and comparison of the operation parameters prior and post to coking on tube in radiation zone was carried out. It was found that residue feedstock high in saturated hydrocarbon, resin and asphaltene contents, low in aromatic content exhibited high coking tendency. Measures, such as using high recycle ratio to increase the ratio of aromatics to asphaltene and to speed up the flow rate of cold oil in radiation zone tubes, adjusting the wall temperature of furnace tube to suppress coking, monitoring the quality of the feedstock were adopted in operation to reduce coking on furnace tubes.
