Opis:
Based on the global goals for cleaner production and sustainable development, the pyrolysis behavior of cephalosporin residues was studied by TG-MS method. The influence of full temperature window on the safe disposal of residues was analyzed based on the “3-2-2” and “1+1” of thermal analysis kinetics, and the gas by-products of thermal degradation were monitored. Results showed that the pyrolysis of distillation residues were divided into low and high-temperature zones, including six stages. Maximum error rate (8.55%) by multiple scan rate was presented based on “3-2-2” pattern and maximum total fluctuation (33.7) by single scan rate was presented based on “1+1” pattern, which implied that the comprehensive multi-level comparison method was very reliable. The E value “E” of six stages showed an increasing trend ranging 166.8 to 872.8 kJ/mol. LgA(mean) was 27.28. Most mechanism function of stage 1, 2 were Z-L-T equation (3D), stage 3, 4, 6 were Avrami-Erofeev equation (AE3, AE4, AE2/3) and stage 5 was Reaction Order (O2). In addition, various small molecular micromolecule substances were detected such as C2H4O, C2H6, NH3, CH4, CO2 under full temperature windows and a possible pyrolysis path of residues was provided.

Opis:
The results of the research on energy usage of the fatty acids distillation residue are presented. Distillation residue constitutes a material of biogenic origin, which is created only as a result of physical processing of animal fats without using additional chemicals. This material exhibits similar physicochemical properties as the heavy heating oil and may be its substitute. Industrial comparative tests of combusting of distillation residue and also of the heavy heating oil in an oil boiler were conducted. The research was conducted at the rated and minimum capacities of the boiler. It has been stated that combusting of the distillation residue of the fatty acids in a tested oil boiler does not bring about any technological difficulties. No threat of the elevated emission of pollutants into the atmosphere was exhibited. Installation of the boiler fulfill all emission standards required for combustion of the liquid fuels. Combustion of fatty acids distillation residue contributes to the reduction of the previous emission of pollutants from burning of the heavy fuel oil, significantly in scope of SO2.
