Marble Sludges as Environmentally Friendly Catalysts in Olive Pomace Pyrolysis: Effect of Sludge Composition on Pyrolysis Products
نویسندگان
چکیده
Waste management of olive pomace is difficult because the high production amount and nonbiodegradable organic substances. Catalytic pyrolysis process one effective methods for (OP) obtaining valuable substances from it. Therefore, in this study, different types marble sludge were used as catalyst at 500°C temperature 40% dose. While K1, K2, K3 are sludges obtained physicochemical treatment travertine type processing wastewater with alum, FeCl3 PEL, respectively, K4, K5 K6 corresponding natural stone wastewater. Pyrolysis product yields characteristics biochars investigated. The highest yield biochar liquid gas fractions was K1 catalyst. OP+K1 has initial decomposition temperature. Biochar by using more granular. having calorific value (1193 cal/g) catalytic OP K4 Biochars catalysts similar values. Besides values, indicated that these can be diverse purposes either additive or feedstock. Consequently, recommended when evaluated terms characteristics.

Characterisation of products from pyrolysis of waste sludges
The pyrolysis of waste sludges was investigated using thermogravimetry/mass spectrometry (TG/MS) and a fixed-bed reactor. Two types of sludge were used, namely mixed sludge and oil sludge. In TGA/MS measurements, two degradation steps were observed. Degradation of organic structures, in sludge took place in the first step, while inorganic materials in sludge were mainly decomposed in a second s...

The thermal degradation of tyrosine at a residence time of 0.2s was conducted in a tubular flow reactor in flowing N2 and 4% O2 in N2 for a total pyrolysis time of 3min. The fractional pyrolysis technique, in which the same sample was heated continuously at each pyrolysis temperature, was applied. Thermal decomposition of tyrosine between 350 and 550°C yielded predominantly phenolic compounds (...
