“…The SPW sample, however, presents a high concentration of coarse particles (\2, 2-20, and [20 lm fractions: 2, 17, and 81%), which is mainly due to the presence of minerals such as quartz and barite. The AC sample has high plasticity (Atterberg plastic index = 31%) and is located inside the acceptable molding region according to the extrusion prognosis [16]. The AC30SPW sample (Atterberg plastic index = 24%), however, moves the workability of the AC sample into the optimum molding region.…”

“…For this reason, the ceramic industry is attractive for reuse of waste materials, including potentially hazardous and noninert industrial wastes. In this way, several works have been published regarding the reuse of different oily sludges of the petroleum industry in the manufacture of clay bricks [4,[10][11][12][13][14][15][16][17][18]. However, in spite of the fact that SPW was produced in large amounts every year, insufficient attention was devoted to the reuse of SPW in clay bricks and roofing tiles.…”

Large amounts of waste materials are discarded in the petroleum exploration industry. This work investigates the incorporation of solid petroleum waste (SPW) as a raw material into a clay body, replacing natural clay material by up to 30 wt%. Ceramic pieces were produced at temperatures varying from 700 to 1,100°C. The technological properties of the clay ceramic pieces (e.g., linear shrinkage, apparent density, water absorption, and compressive strength) have been determined. Development of the sintered microstructure was followed by scanning electron microscopy (SEM) and X-ray diffraction analyses. The leaching toxicity of the fired pieces has also been determined. The results showed that the SPW could be used in clay-based ceramics (clay bricks and roofing tiles), in the range up to 30 wt%, as a partial replacement for natural clay material. The leaching concentrations of Ag, As, Ba, Cd, Cr (total), Hg, and Pb of the fired pieces met the Brazilian regulatory requirements. These results suggest that the SPW can be valorized for manufacturing claybased ceramics, and at the same time, this application can help in reducing the environmental impacts of the petroleum exploration industry.

“…In this past decade, several publications [30][31][32][33][34][35][36][37][38][39] provided important information on the properties of red ceramics incorporated with oily residues. In particular, the increase in mechanical strength resulting from a ten percent of oily residue was indeed confirmed and an explanations of the role of hydrocarbon content on the ceramic microstructure was proposed [30,38].…”

A review on the fundamentals and technological advances in the incorporation of industrial solid wastes into red ceramics was updated since 1997, when the first overview on this subject was published by Dondi, Marsigli and Fabbri. Other works conducted before this period, but not covered by that overview were also reviewed. Modifications were introduced in the original categories of wastes to permit a wider variety to be considered. In addition to fuel and fluxing wastes, a category of property affecting wastes substituted the originally proposed fly-ash and plasticity reducing/ plastifying wastes categories. In order to be more comprehensive, this updated review considered industrially relevant subdivisions within each category. Accordingly, fuel wastes encompass: oily residues, blast furnace sludge, and paper industry residues. Fluxing wastes encompass: rejects from ornamental rocks, glassy residues and fluxing ashes. Property affecting wastes encompass: grog, water treatment sludge, steel-refining sludge/slag, non-fluxing ashes, mineral processing tails, galvanic sludge, spent catalyst reject, textile slurry, foundry reject sands, tannery sludge and construction and demolition leftovers.

ABSTRACT. Wet air oxidation (WAO) of oily sludge was carried out using Fe 3+ as catalyst, placed in a 0.5 L batch autoclave in the temperature range of 250-330 o C. Experiments were conducted to investigate the effects of temperature, the initial COD, reaction time, concentration of catalyst and O2 excess (OE) on the oxidation of the oily sludge. The results showed that in the WAO 88.4% COD was achieved after 9 min reaction at temperature of 330 o C, OE of 0.8 and the initial COD of 20000 mg/L. Temperature was found to have a significant impact on the oxidation of oily sludge. Adding a catalyst significantly improved the COD removal. Homogenous catalyst, Fe 3+, showed effective removal for pollutants. COD removal was 99.7% in the catalytic wet air oxidation (CWAO) over Fe 3+ catalyst. The results proved that the CWAO was an effective pretreatment method for the oily sludge.
