Cassava skin waste is waste originating from cassava plants from tapioca flour factories or cassava processed product factories. Indonesia is one of the biggest countries that produces cassava. The number of cassava processing industries in Indonesia is large so that a positive correlation can be drawn that the high amount of cassava processed will produce more cassava skin waste. Based on the results of tests conducted, the higher the composition of the Each cassava can produce 10-15% of cassava skin waste. Cassava skin waste is directly removed, can cause buildup that results in environmental damage. Cassava skin waste is obtained from local farmers, where on average each cassava produces 10-15% of waste. In general, this waste is not used and just thrown away. This research was conducted with the main ingredients of cassava peel waste and adhesive made from used paper. The composition of the mixture of cassava peel and used paper varies, where the percentage by weight of the adhesive starts from 7.0% to 10% with an increase in the composition every 0.5%. Then the biobriquette carbonization process was carried out at a temperature of 400 ° C. The biobriquette characterization was carried out based on ASTM standards to analyze water and ash, volatile matter and heating value. The results of the analysis on the composition of the lowest cassava bark had the highest heating value of 5888 cal / gr with the lowest water, ash and volatile matter content.

The purpose of this research is to know the characteristics of briquettes including ash content, moisture content, volatile matter content, heating value, density, burning rate, tensile strength and to know the proper ratio of water hyacinth and coconut shell mixture under tapioca gluten variation. The ratios of water hyacinth and coconut shell in this research were 1:1, 1:2, 1:3, 1:4 with variation of tapioca gluten 5%, 10%, and 15% of the raw materials. From this research, the ideal composition of briquette is obtain in a mixture of water hyacinth and coconut shell at a ratio of 1:4 with tapioca gluten 10%, ash content 9.718%, moisture content 1.374%, volatile  matter content 14.814%, heating value 6,879.596 cal/g, density 0.983 g/cm3, burning rate 3.021 × 10-3 g/second and tensile strength 18.400 g/cm2.

Coke producers often face a shortage of valuable grades of coals, i.e. coking coals. This paper examines the possibility to obtain a coking additive by applying delayed coking to various types of heavy petroleum residues. The paper also gives a comparative description. Five types of heavy petroleum residue from the KINEF oil refinery were used in the experiments that aimed to produce carbon material. They included vacuum residue ELOU-AVT-6, vacuum residue S-1000 resultant from the hydrocracking process, visbreaker bottoms from the S-3000 unit, and two mixtures of the ELOU-AVT-6 unit products: a mixture of vacuum residue and third vacuum cut; and a mixture of vacuum residue, third vacuum cut and atmospheric residue. The carbon material obtained from all the above types of raw materials was analyzed for quality; an X-ray diffraction analysis was carried out; and the interplanar spacings d002 and d110 were calculated, as well as the linear sizes of Lc and La crystallites. The coking additive obtained instead of the typical petroleum coke was found to meet the specification. Thus, the volatile matter content in it is within the range from 15 to 25 wt%. This additive can be used in steel production instead of coking coal. The coking additive from a mixture of vacuum residue, third vacuum cut and atmospheric residue has the highest content of volatile matter (19.30%), while the coking additive from the visbreaking residue from the S-3000 has the lowest volatile matter content (16.15%). The latter is due to the fact that the primary petroleum material was subjected to light thermal cracking. It is shown that as the composition of the heavy petroleum residue changes, so do the properties of the resultant coking additive: a higher fraction of the low-boiling components in the feedstock is associated with a higher volatile matter content; the carbon materials produced from vacuum residue have a higher microhardness; the coking product produced from the visbreaker bottoms has a lower porosity compared with the product obtained from the vacuum residue. This research was carried out as part of a governmental assignment of the Ministry of Education and Science of the Russian Federation in the framework of the following research project: 0792-2020-0010 “Fundamentals of innovative processing techniques to obtain environmentally-friendly motor fuels and innovative carbon materials with variable macro- and microstructure of the mesophase from heavy hydrocarbon materials”. The research was carried out at the laboratory of the Shared Knowledge Centre of the Saint Petersburg Mining University.
