This article contains the most optimum temperature requirements for hydrogenation reaction by Pd- PEG/ZnO catalyst. Works of some foreign authors have been investigated due to to create catalysts for the preparation of which energy consumption will be negligible and the catalyst activity will remain the same.

In the article presents the results of studies on the effect of temperature and pressure on the chloride sublimation of zinc and lead from converter dusts of steel production. Currently, an objective necessity is the development of dust utilization technologies for converter steel production, with its further use in production and production of by-products. The use of dust allows not only to save natural raw materials, but also increases production efficiency and improves the environmental situation. The content of non-ferrous metals in dusts makes it difficult to process and use them in agglomeration or in blast furnace production, while the iron content in converter dusts (sludges) makes it possible to use them as promising metallurgical raw materials. Therefore, for a more complete processing of dusts, extraction of non-ferrous metals from them is proposed. The purpose of this work was to determine the possibility of extracting zinc and lead from sludges of the converter production by the method of chloride sublimation. We used dust containing: 86,3 % Fe2O3, 3,5 % FeO, 0,9 % Al2O3, 1,6 % CaO, 0,9 % MgO, 1,1 % MnO, 0,8 % SiO2, 4,4 % ZnO, 0,5 % PbO. The study was conducted in the temperature range 200-1600 degrees C and pressures of 0,01; 0,1 and 1 bar based on a complete thermodynamic analysis using the HSC – 5.1 software package. Finnish metallurgical company Outokumpu, based on the principle of minimum Gibbs energy. According to the results of the studies, it was found that, at normal pressure, lead chloride sublimationbegins at a temperature of 600 degrees С, and zinc - at 900 degrees С: a decrease in pressure to 0,01 bar reduces the temperature to 500 degrees С and 700 degrees С, respectively; lead chloride sublimation under equal conditions is more complete than zinc; To achieve zinc chloride distillation at the level of 90-96 %, the process must be carried out at 1145-1200 degrees С and pressure from logP = -2 to 1,2 bar, while the degree of lead chloride distillation is 99,8-100 %.

Environmental protection measures are based, among other things, on the rationalization of the organization of the production waste management process. Population growth and the race to industrialize pose a serious threat to the ecosystem. Currently, the average global waste generation per capita is 494 kg / year. A large number of industrial enterprises operate on the territory of Kazakhstan. The range of manufactured products is very wide: household items, transport, building materials, equipment and much more. Each type of production is inevitably a source of a large amount of industrial waste, annually at the enterprises of Kazakhstan up to 600 million tons of waste are generated, three percent of which are recycled. On the territory of Pavlodar region there are enterprises in the field of metallurgy, mechanical engineering, chemical industry, construction industry enterprises, light industry, about a hundred in total. In this connection, the problem of treatment and disposal of industrial waste in Pavlodar region is very relevant. The article discusses the system of waste management in order to reduce their impact on the environment, activities for the disposal, transportation, disposal of waste, as well as their disposal at the industrial waste landfill in Pavlodar. The landfill in question is intended for the reception, temporary storage and disposal of non-hazardous solid industrial waste of the «green» level: waste and scrap of chromium, cadmium, aluminum, copper, lead, zinc, manganese, plastic waste, polyethylene, abrasive, rubber waste, ash and ash and slag waste; and also «amber»: waste containing mercury, arsenic, lead, waste batteries, phosphoric slags, waste oils, oil sludge. The scheme of organizing waste storage works is considered. The volume of accepted and recycled waste, as well as those placed at the landfill and used for their own needs, was analyzed, including construction waste, waste sleepers, ash and slag and abrasive scrap. The solution to the problem of industrial waste disposal is associated with the need for innovation and the introduction of new technologies and equipment.
