As pesquisas de campo foram realizadas na região paulista do Médio Paranapanema, no período de janeiro a dezembro de 2007, avaliando-se o consumo energético referente às fases de produção e processamento industrial. Verificou-se que o custo energético total da produção agrícola correspondeu a 14.370,9MJ ha-1, e o item mais oneroso foi o de insumos (50,4%). Nas etapas industriais, o consumo energético foi equivalente a 1.641,6MJ t-1. As operações de hidrólise, sacarificação e tratamento do caldo representaram 71,7% do dispêndio energético total. Na cana-de-açúcar, observou-se um custo energético de 2,0MJ L-1 em relação ao etanol produzido nas principais operações agronômicas de produção e 19,4MJ L-1 nas etapas de processamento industrial. A eficiência energética no cultivo e na industrialização foi de 1,1. This research analyzed the energetic consumption of the etanol, using as raw-material sugar cane. The searches were carried out from the field in the Midle Paranapanema River Region, Sao Paulo state, in the period from January to December 2007. The referring energy consumption from the crop production phase and industrial processing were evaluated. It was verified that the total energetic cost of the crop production corresponded to 14370.9MJ ha-1, and the most onerous item was the inputs (50.4%). In the industrial step, the energetic consumption was equivalent to 1,641.56MJ t-1. The 'hydrolysis, saccharification and broth treatment operations' represented 71.72% of the total energetic expenditure. It was also observed an energetic cost of 2.0MJ L-1 in relation to the etanol produced in the main crop production operations, and 19.4MJ L-1 in the industrial processing. The energy efficiency observed in the crop production and industrialization were of 1.1.

Abstract

This paper aims to analyze the information about protection of technologies related to distributed generation (DG) of electric energy, available in the Brazilian patent bank, in the period between 2011 and 2020. Considering that the energy sector has strategic role for companies and countries, analyzing technological trends in the area can help management and decision making. As a methodological procedure, (1) data were collected from the national database of the Instituto Nacional de Propriedade Industrial - INPI (National Institute of Industrial Property) -- in July 2020, (2) associated with keywords and the Classificação Internacional de Patentes - IPC (International Patent Classification) for research and (3) treated with the aid of Microsoft Excel and IBM SPSS Statistics version 25 software. The variables found and analyzed were: nature of the patent; order status; international classification; year of filing; publication of request; countries of origin of depositors; main depositors; state of origin of depositors; electrical system structure; and types of energy sources. The results demonstrated that the number of patent filings fluctuated over the years; that there was a significant growth in the number of deposits in the years that normative resolution n° 482/2012, responsible for regularizing DG in Brazil, was published or revised and that most of the technologies deposited are intended for power generation, with emphasis on that use wind energy.
