Former taxi driver Ji Zhongxing went on trial last month for endangering public safety. Ji was the only person injured in the July 20 explosion.
The Beijing Chaoyang District Court said on its microblog that Ji's lawyers and relatives were on hand for the verdict and sentence today.
Ji's lawyer Li Xiaoyuan said his client had hoped to attract police so he could be detained and discuss his beating in 2005 by city security guards in the Guangdong city of Dongguan.
